Description

Ship energy system and ship including the same, method for separating a ship's nuclear reactor

[0001] The present invention relates to a ship energy system, a ship including the same, and a method for separating a ship's nuclear reactor.

[0002] Generally, ships obtain propulsion by utilizing energy generated from burning fuel.

[0003] Recently, alternative fuels such as liquefied natural gas (LNG) and liquefied petroleum gas (LPG) are being applied to some vessels, and along with this, various next-generation propulsion technologies, including hydrogen fuel, fuel cells, and nuclear propulsion systems, are being researched to improve energy efficiency and eco-friendliness.

[0004] However, due to the strengthening of environmental regulations adopted by the International Maritime Organization (IMO), particularly the demand to reduce greenhouse gas emissions, restrictions are gradually being placed on the operation of ships using carbon-based fuels such as oil and coal.

[0005] Accordingly, there is an increasing need for eco-friendly propulsion systems capable of minimizing the generation of carbon dioxide (CO2) and other harmful emissions, and ship propulsion technology using Small Modular Reactors (SMRs) is attracting attention as an alternative.

[0006] Small Modular Reactors (SMRs) are designed with relatively small power outputs and feature a modular structure that facilitates easy fabrication, installation, and maintenance. Furthermore, by offering higher safety and the possibility of rapid installation compared to conventional large reactors, they are recognized as a suitable nuclear propulsion solution for maritime environments characterized by limited space and harsh operating conditions. In particular, SMRs enable long-distance voyages and energy self-sufficiency, providing significant advantages in the maritime transport sector where fuel supply constraints are severe.

[0007] However, when applying SMRs to ships, the issue of handling radioactive waste inevitably generated during reactor operation is critical; therefore, the development of technologies capable of safely storing, managing, and finally disposing of radioactive materials on board is essential.

[0008] Accordingly, technology development for the management of radioactive waste and ensuring safety is continuing in order to commercialize SMR-based ship propulsion systems.

[0083] The present invention is capable of various modifications and may have various embodiments; specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various forms.

[0084] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted.

[0085] In the following examples, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0086] In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added.

[0087] Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described. For example, two processes described consecutively may be performed substantially simultaneously or proceed in the reverse order of the description.

[0088] In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, so the following embodiments are not necessarily limited to those illustrated.

[0089] FIG. 1 is a drawing illustrating a ship (1) according to one embodiment of the present invention, and FIG. 2 is a drawing illustrating an energy generation module (100) and an energy conversion module (200) of the ship energy system (10) of FIG. 1.

[0090] Referring to FIGS. 1 and FIGS. 2, the ship (1) may be equipped with a hull (2) and a ship energy system (10).

[0091] The hull (2) forms the exterior of the ship (1) and can operate by receiving power from the ship energy system (10). The ship energy system (10) can produce the power required for the operation of the ship (1).

[0092] The ship energy system (10) may be equipped with an energy generation module (100) and an energy conversion module (200).

[0093] The energy generation module (100) can generate thermal energy by utilizing the nuclear reaction of nuclear fuel material. The energy conversion module (200) can convert the thermal energy generated by the energy generation module (100) into power. The power converted by the energy conversion module (200) can be supplied to and utilized by all systems necessary for the operation of the ship (1), such as the propulsion system.

[0094] The energy generation module (100) and the energy conversion module (200) can be modularized and arranged within the hull (2). The energy generation module (100) and the energy conversion module (200) can be modularized and each accommodated in a predetermined sealed area within the hull (2).

[0095] In one embodiment, the energy generation module (100) may be provided so as to be detachable within a sealed area. As shown in FIG. 2, the energy generation module (100) and the energy conversion module (200) may be placed below the deck (DK) of the hull (2).

[0096] The deck (DK) may be equipped with an openable slide door section (SD). The energy generation module (100) may be inserted into the lower part of the deck (DK) through the slide door section (SD) or moved outside the hull (2). In this way, the energy generation module (100) has a modular structure that is separable from the hull (2), so that it can be easily installed and maintained.

[0097] The energy generation module (100) may be equipped with a nuclear reactor (110) and a heat transfer line (CCL).

[0098] The thermal energy generated by the nuclear fission reaction in the reactor (110) can be transferred along the heat transfer line (CCL).

[0099] In one embodiment, a steam generator (120), a pressurizer (130), and a pump (140) may be arranged on a heat transfer line (CCL), and a coolant may flow along the heat transfer line (CCL). The coolant that has absorbed thermal energy from the reactor (110) may be introduced into the steam generator (120) while being pressurized by the pressurizer (130).

[0100] The coolant is discharged after exchanging heat with the working fluid in the steam generator (120) and can be returned to the reactor (110) by the pump (140). In this way, the coolant can circulate along the heat transfer line (CCL) and transfer thermal energy.

[0101] The energy generation module (100) may further be equipped with a shielding unit (150).

[0102] The shielding unit (150) can shield radiation generated as a nuclear fission reaction occurs in the reactor (110). The shielding unit (150) can form a predetermined sealed space in which each component of the energy generation module (100), including the reactor (110), can be arranged, and can shield radioactive materials. Additionally, the working fluid can flow through a pipe penetrating the shielding unit (150).

[0103] In one embodiment, the shielding unit (150) may have a first shielding section (151), a second shielding section (152), and a third shielding section (153). The first shielding section (151) primarily surrounds the reactor (110) and the components connected thereto, and the second shielding section (152) may be formed to surround the first shielding section (151). Additionally, the third shielding section (153) may be positioned between the first shielding section (151) and the second shielding section (152).

[0104] For example, the first shielding section (151) and the second shielding section (152) may be made of bulkheads including SUS or concrete, and the third shielding section (153) may be light water placed between the two bulkheads. In this way, the energy generation module (100) has a multi-shielding structure and can safely shield radiation generated from the reactor (110).

[0105] Meanwhile, the configuration, heat transfer method, and shielding structure of the energy generation module (100) described above are exemplary, and the energy generation module (100) can be equipped with any structure capable of generating a nuclear fission reaction in a nuclear reactor (110) and transferring the thermal energy generated by the nuclear fission reaction to an energy conversion module (200). In addition, the types of nuclear fuel material and coolant are not particularly limited.

[0106] The energy conversion module (200) may be equipped with a turbine (210), a working fluid inlet line (WIL), and a working fluid outlet line (WOL).

[0107] The energy conversion module (200) can convert thermal energy into power by allowing a working fluid to flow and transferring thermal energy to a turbine (210).

[0108] A working fluid can flow along the working fluid inlet line (WIL) and the working fluid outlet line (WOL). The working fluid inlet line (WIL) and the working fluid outlet line (WOL) can each be connected to an energy generation module (100).

[0109] The working fluid can flow into the energy generation module (100) along the working fluid inlet line (WIL) to receive thermal energy, and then move to the turbine (210) along the working fluid outlet line (WOL). The turbine (210) can rotate by the working fluid and generate power.

[0110] In one embodiment, the energy conversion module (200) may be equipped with a generator (220), a condenser (230), and a pump (240). Power generated from the turbine (210) can be converted into electricity in the generator (220) and supplied to all systems necessary for the operation of the vessel (1).

[0111] The working fluid that supplies thermal energy to the turbine (210) can be condensed in the condenser (230) and moved back to the energy generation module (100), and its flow can be controlled by the pump (240). The working fluid can repeat the above flow process, and through this, the energy conversion module (200) can convert thermal energy into power.

[0112] The energy conversion module (200) may be provided with a bulkhead (250) having a sealed internal space, and the bulkhead (250) may also have a shielding structure for radiation shielding. A turbine (210), etc., may be accommodated within the bulkhead (250). Additionally, the working fluid may flow through a pipe penetrating the bulkhead (250).

[0113] Meanwhile, the configuration and power conversion method of the energy conversion module (200) described above are exemplary and can be provided in any structure capable of receiving thermal energy from the energy generation module (100) and converting it into power. In addition, the type of working fluid is not particularly limited.

[0114] In this way, the thermal energy generated in the energy generation module (100) can be transferred to the energy conversion module (200) through the working fluid and converted into power. That is, the working fluid can be configured to flow between the energy generation module (100) and the energy conversion module (200).

[0115] For the flow of the working fluid, the energy generation module (100) and the energy conversion module (200) may be connected by one or more pipes. Meanwhile, the working fluid may flow into the energy generation module (100), absorb thermal energy, and then flow out of the energy generation module (100); at this time, the working fluid in the pipe connected to the energy generation module (100) may contain radioactive material.

[0116] As described above, the energy generation module (100) may be provided with a modular structure that is separable from the hull (2), and for the separation of the energy generation module (100), the piping connecting the energy generation module (100) and the energy conversion module (200) also needs to be separated.

[0117] Since a working fluid containing radioactive material may flow within the piping connecting the energy generation module (100) and the energy conversion module (200), it is necessary to safely remove the remaining working fluid before separating the piping.

[0118] Accordingly, the ship energy system (10) of the present invention is equipped with a fluid drain unit (1000) on a line connected to an energy generation module (100) so that radioactive fluid can be safely drained, and the modularized energy generation module (100) can be easily separated and discharged outside the hull (2) after the fluid is drained.

[0119] The ship energy system (10) may further be equipped with a fluid drain unit (1000).

[0120] A fluid drain unit (1000) can be placed on all lines extending from the energy generation module (100). The fluid drain unit (1000) can safely drain and process or store fluid flowing out from the energy generation module (100).

[0121] A fluid drain unit (1000) can be placed on the piping connecting the energy generation module (100) and the energy conversion module (200). The fluid drain unit (1000) can safely dispose of the working fluid within the piping connecting the energy generation module (100) and the energy conversion module (200) by discharging it outside the piping.

[0122] A fluid drain unit (1000) may be provided in at least one of a working fluid inlet line (WIL) and a working fluid outlet line (WOL). In particular, since the working fluid that absorbs thermal energy from the energy generation unit and is discharged may contain radioactive material, the fluid drain unit (1000) may be placed on the working fluid outlet line (WOL) to safely process the working fluid containing radioactive material.

[0123] That is, the fluid drain unit (1000) can be connected to the energy generation module (100) and installed on any line through which the radioactive fluid can flow.

[0124] Meanwhile, the following description focuses on an embodiment in which a fluid drain unit (1000) is provided on a pipe connecting an energy generation module (100) and an energy conversion module (200). In this case, the fluid drain unit (1000) can drain working fluid that flows through the pipe or remains in the pipe.

[0127] First, the energy generation module (100) and the energy conversion module (200) can be connected by connecting pipes extending from each other. Through this, the energy generation module (100) can be easily separated from the hull (2) by disconnecting the pipes when necessary.

[0128] Hereinafter, the pipe extending from the energy generation module (100) is defined as the first pipe (PP1), and the pipe extending from the energy conversion module (200) is defined as the second pipe (PP2). When the first pipe (PP1) and the second pipe (PP2) are connected, they can function as a connecting pipe that connects the energy generation module (100) and the energy conversion module (200).

[0129] The first pipe (PP1) and the second pipe (PP2) can be connected by a pipe connecting member (PC). The first pipe (PP1) and the second pipe (PP2), connected by the pipe connecting member (PC), can communicate with each other so that fluid can flow.

[0130] The pipe connecting member (PC) can be provided in any structure or form that connects the end of the first pipe (PP1) and the end of the second pipe (PP2) to allow fluid to flow continuously. For example, the pipe connecting member (PC) may have a flange structure and be secured with bolts, etc. Additionally, the pipe connecting member (PC) may further be provided with a sealing member for sealing.

[0131] The fluid drain unit (1000) may be equipped with a valve unit (1100), a power supply unit (1200), and a drain unit (1300).

[0132] The valve unit (1100) can control the flow of fluid within the first pipe (PP1) and the second pipe (PP2) that are connected to each other.

[0133] The valve unit (1100) may be equipped with a first valve (1110) and a second valve (1120). The first valve (1110) and the second valve (1120) may be placed on a first pipe (PP1) and a second pipe (PP2), respectively. That is, a pipe connecting member (PC) may be located between the first valve (1110) and the second valve (1120).

[0134] The first valve (1110) and the second valve (1120) can be controlled to open or close simultaneously or selectively.

[0135] The power supply unit (1200) can provide power for opening and closing the valve unit (1100). The power supply unit (1200) can be connected to the first valve (1110) and the second valve (1120), respectively, to supply power. The first valve (1110) and the second valve (1120) can be opened or closed by receiving power.

[0136] In one embodiment, the power supply unit (1200) may receive thermal energy generated from the nuclear reactor (110) and supply power generated from it to the valve unit (1100). Alternatively, the power supply unit (1200) may be equipped with a separate battery to supply power to the valve unit (1100).

[0137] The drain section (1300) can drain fluid within the pipe connecting the energy generation module (100) and the energy conversion module (200).

[0138] The drain section (1300) can drain fluid when the first valve (1110) and the second valve (1120) are closed. At this time, working fluid remaining in the connecting pipe can be discharged to the outside of the pipe by the drain section (1300).

[0139] Alternatively, the drain section (1300) may drain fluid while at least one of the first valve (1110) and the second valve (1120) is open. Through this, the fluid flowing between the energy generation module (100) and the energy conversion module (200) may be drained immediately.

[0140] The drain section (1300) may be equipped with a drain pipe (1310), a drain pump (1320), and a filter (1330).

[0141] The drain pipe (1310) may be installed to communicate with the connecting pipe. The drain pipe (1310) may communicate with the discharge port (EX) provided in the hull (2). The working fluid in the connecting pipe connecting the energy generation module (100) and the energy conversion module (200) may be discharged to the discharge port (EX) along the drain pipe (1310). Through this, the working fluid may be discharged into the ocean.

[0142] A drain pump (1320) is positioned in the drain pipe (1310) to control the flow of fluid. The fluid in the pipe connecting the energy generation module (100) and the energy conversion module (200) is sucked in by the drain pump (1320) and flows along the drain pipe (1310) to be discharged to the outlet (EX).

[0143] A filter (1330) is placed in the drain pipe (1310) and can filter the fluid flowing along the drain pipe (1310). After radioactive material in the fluid is removed by the filter (1330), it can be discharged into the ocean through the outlet (EX).

[0144] In one embodiment, the drain section (1300) may be positioned adjacent to the first valve (1110) as shown in FIG. 3. The drain pipe (1310) may be installed at a location relatively closer to the first valve (1110) than to the second valve (1120). This allows the radioactive fluid flowing from the energy generation module (100) to be processed more quickly and efficiently.

[0145] In another embodiment, the drain section (1300') may be positioned adjacent to the second valve (1120') as shown in FIG. 4. The drain pipe (1310') may be installed at a location relatively closer to the second valve (1120') than to the first valve (1110'). This allows the energy generating module (100) to be easily separated from the hull (2) when the pipe connection member (PC) is released.

[0146] FIG. 5 is a drawing illustrating a fluid drain unit (1000A) according to another embodiment of the present invention.

[0147] The fluid drain unit (1000A) according to the embodiment of FIG. 5 differs from the fluid drain unit (1000) of FIG. 3 in the configuration and processing method of the drain section (1300A). Therefore, the following description will focus on this, and for other configurations, the details described above regarding FIG. 3 will be referenced.

[0148] The drain section (1300A) may be equipped with a drain pipe (1310A) and a drain tank (1340A).

[0149] The drain pipe (1310A) can be installed to communicate with the pipe extending from the energy generation module (100). The drain pipe (1310A) can connect the connecting pipe and the drain tank (1340A). The working fluid in the connecting pipe can flow into the drain tank (1340A) along the drain pipe (1310A).

[0150] The drain tank (1340A) is connected to the drain pipe (1310A) and can store the drained fluid. The drain tank (1340A) has a shielded structure and can safely store the radioactive fluid. The fluid drain unit (1000A) drains the radioactive fluid and stores it in the drain tank (1340A), and can then discharge it outside the hull (2) when the ship (1) is docked, etc.

[0151] In addition, as described in FIG. 3, etc., the drain portion (1300A) may be positioned adjacent to the first valve (1110A) as in FIG. 5, or may be positioned adjacent to the second valve (1120A).

[0152] In this way, the fluid drain unit (1000) is extended from the energy generation module (100) and provided on a pipe through which radioactive fluid can flow, so that the radioactive fluid can be safely drained for processing or storage.

[0153] In particular, when an energy generation module (100) including a reactor (110) needs to be separated and discharged outside the hull (2), the energy generation module (100) can be safely and easily separated from the hull (2) by dismantling the pipe connection member (PC) after the fluid drain unit (1000) has safely drained the remaining working fluid in the connecting pipe while the valve unit (1100) is closed.

[0154] FIG. 6 is a flowchart illustrating a method for separating a shipboard reactor according to one embodiment of the present invention.

[0155] Referring to FIG. 6, the method for separating a ship's nuclear reactor may include the steps of: closing a first valve placed in a first pipe connected to an energy generation module and a second valve placed in a second pipe connected to an energy conversion module (S100); draining a working fluid placed between the first valve and the second valve through a drain pipe (S200); separating the first pipe and the second pipe connected by a pipe connecting member between the first valve and the second valve (S300); and opening a slide door section placed on the deck to discharge the energy generation module to the outside of the hull (S400).

[0156] The step (S100) of closing the first valve disposed in the first pipe connected to the energy generation module and the second valve disposed in the second pipe connected to the energy conversion module may close the first valve and the second valve, respectively, disposed in the first pipe and the second pipe connecting the energy generation module and the energy conversion module. The first pipe and the second pipe are connected by a pipe connecting member, so that fluid can flow through them in communication with each other. At this time, the reactor equipped in the energy generation module may be in a stopped state. Additionally, when the first valve and the second valve are closed, a predetermined working fluid may remain in the first pipe and the second pipe.

[0157] The step (S200) of draining the working fluid positioned between the first valve and the second valve through the drain pipe allows the fluid drain unit to drain the working fluid positioned between the first valve and the second valve. The drain pipe may communicate with the first pipe and the second pipe, i.e., the connecting pipe, so that fluid can flow through it. After both the first valve and the second valve are closed, the working fluid remaining in the first pipe and the second pipe can be drained through the drain pipe.

[0158] At this time, the working fluid is drawn in through a drain pump and can be discharged outside the hull after passing through a filter to remove radioactive materials. Alternatively, the working fluid can flow along a drain pipe and be stored in a shielded drain tank.

[0159] The step (S300) of separating the first pipe and the second pipe connected by a pipe connecting member between the first valve and the second valve can be performed by dismantling the pipe connecting member to separate the first pipe and the second pipe. The pipe connecting member is provided with any structure capable of connecting the first pipe and the second pipe, such as a flange structure, and the first pipe and the second pipe can be separated by dismantling the pipe connecting member after the working fluid remaining in the first pipe and the second pipe has been removed.

[0160] The step (S400) of opening a slide door section positioned on the deck to discharge an energy generation module to the outside of the hull involves opening the slide door section of the deck, and allowing the energy generation module to be discharged to the outside of the hull through the opened slide door section. Since the first pipe and the second pipe are separated, the energy generation module of the modular structure can be easily separated and moved to the outside of the hull.

[0161] A ship energy system and a ship reactor separation method according to one embodiment of the present invention provide a fluid drain unit on a line extending from an energy generation module, so that fluid within the piping can be safely drained, stored, and processed when necessary. In particular, a ship energy system and a ship reactor separation method according to one embodiment of the present invention can safely drain the working fluid within the piping connecting the energy generation module and the energy conversion module, and then easily discharge only the energy generation module to the outside of the hull by dismantling the piping connection member.

[0162]

[0163] Hereinafter, a ship energy system (2010) according to another embodiment of the present invention and a ship (1') including the same will be described.

[0164] FIG. 7 is a drawing illustrating a vessel (1') according to another embodiment of the present invention, FIG. 8 is a plan view schematically illustrating the stern region (AA) of the vessel (1') of FIG. 7, and FIG. 9 is a perspective view schematically illustrating the stern region (AA) of the vessel (1') of FIG. 7.

[0165] Referring to FIGS. 7 to 9, the ship (1') may be equipped with a hull (2002) and a ship energy system (2010).

[0166] The hull (2002) forms the exterior of the ship (1') and can be propelled by receiving power from the ship energy system (2010). A propeller (PP) is positioned in the stern region (AA) of the hull (2002), and the propeller (PP) can be driven by receiving power from the ship energy system (2010).

[0167] A pair of propellers (PP) may be provided on the hull (2002). In this specification, a pair of propellers disposed on the hull (2002) will be defined as a first propeller (PP1) and a second propeller (PP2). The first propeller (PP1) and the second propeller (PP2) may be spaced apart from each other in the stern region (AA) of the hull (2002).

[0168] A predetermined area of ​​the stern region (AA) of the hull (2002) may be formed concavely. A predetermined area between the first propeller (PP1) and the second propeller (PP2) in the hull (2002) may be formed concavely from the outer surface of the hull (2002).

[0169] In detail, the area between the first propeller (PP1) and the propulsion shaft connected thereto and the second propeller (PP2) and the propulsion shaft connected thereto can be drawn in from the outer surface of the hull (2002).

[0170] Although not shown in the drawing, the first propeller (PP1) and the second propeller (PP2) may each be connected to a propulsion shaft extending in the first direction (DR1), and may be driven by receiving power from the ship energy system (2010) through the propulsion shaft. Since the propulsion shaft is not positioned in the area between the first propeller (PP1) and the second propeller (PP2) on the hull (2002), the outer surface of the hull may be recessed inward. Accordingly, a predetermined area may be formed concavely in the first direction and the third direction, respectively, from the outer surface of the hull (2002) at the lower part of the stern area (AA) of the hull (2002).

[0171] In this specification, the above-mentioned area that is concavely recessed in the hull (2002) is defined as a recess (RC).

[0172] The ship energy system (2010) is equipped with a reactor module (2100) and can generate thermal energy and convert it into power through the nuclear fission reaction of fuel material. Additionally, the ship energy system (2010) may be equipped with a drain module (2300) that drains and stores fuel material from the reactor module (2100).

[0173] The reactor module (2100) and the drain module (2300) can each be modularized and arranged. The reactor module (2100) and the drain module (2300) can each be accommodated in a specific area within the hull (2002), but can be modularized and provided so as to be detachable from said area. Through this, the ship energy system (2010) can be easily installed in the hull (2002) and can be quickly and efficiently separated, discharged, or maintained when necessary.

[0174] For example, referring to FIG. 10 which will be described later, the reactor module (2100) and the drain module (2300) can each be installed by being inserted into the hull (2002) through the upper slide door (USD).

[0175] An upper slide door (USD) may be provided on the upper deck of the hull (2002) to be openable and closable. When the upper slide door (USD) is opened, a reactor module (2100) and a drain module (2300) can be installed inside the hull (2002) through the open area. Additionally, the reactor module (2100) and the drain module (2300) inside the hull (2002) can be easily removed and retrieved outside the hull (2002) through the open area when the upper slide door (USD) is opened, allowing for convenient maintenance and repair.

[0176] The ship energy system (2010) may be positioned on the upper part of the recess (RC). The ship energy system (2010) may be housed within the hull (2002) but positioned on the upper part of the recess (RC). In this way, in case of emergency, the drain module (2300) can be separated from the ship energy system (2010) and discharged outside the hull (2002) through the recess (RC).

[0177] FIG. 10 is a drawing illustrating the detailed configuration of the ship energy system (2010) of FIG. 7.

[0178] Referring to FIG. 10, the ship energy system (2010) may be equipped with a reactor module (2100), an energy conversion unit (2200), and a drain module (2300).

[0179] The reactor module (2100) may be equipped with a reactor (2110) and a reactor shielding unit (2150).

[0180] Thermal energy can be generated as fuel material undergoes a nuclear fission reaction in a nuclear reactor (2110).

[0181] Fuel material is defined as a material in which nuclear fuel exists in a molten salt state, and can be selected from various materials such as LiF, BeF2, ThF4, UF4, or combinations thereof. The fuel material can undergo nuclear fission in the reactor (2110) and flow while absorbing thermal energy.

[0182] The reactor shielding unit (2150) can shield radiation generated as a nuclear fission reaction occurs in the reactor (2110). The reactor shielding unit (2150) can form a predetermined sealed space in which the reactor (2110) is housed. In this specification, the sealed space formed by the reactor shielding unit (2150) is defined as the reactor section (RR).

[0183] The reactor shielding unit (2150) can shield radioactive materials of the reactor section (RR).

[0184] In one embodiment, the reactor shielding unit (2150) may have a first reactor shielding section (2151), a second reactor shielding section (2152), and a third reactor shielding section (2153).

[0185] The first reactor shield (2151) primarily surrounds the reactor (2110), and the second reactor shield (2152) may be provided to surround the first reactor shield (2151). Additionally, a third reactor shield (2153) may be positioned between the first reactor shield (2151) and the second reactor shield (2152).

[0186] The multi-structure and shielding principle of the reactor shielding unit (2150) will be explained in detail below.

[0187] The energy conversion unit (2200) is connected to the reactor module (2100) and can receive thermal energy generated from the reactor (2110) and convert it into power.

[0188] The energy conversion unit (2200) may include a steam turbine (2210) and a generator (2220).

[0189] The steam turbine (2210) can produce power using a working fluid supplied from the reactor module (2100), where the working fluid can be defined as a fluid that has absorbed thermal energy generated in the reactor (2110).

[0190] The steam turbine (2210) can be connected to the reactor module (2100) via a working fluid line (SL). The working fluid can flow from the reactor module (2100) to the steam turbine (2210) via the working fluid line (SL). In this specification, 'line' may refer to any type of part or device through which fluid can move, such as pipes or duct assemblies.

[0191] The reactor module (2100) has a modular structure that is detachably disposed within the hull (2002), and the working fluid line (SL) can also be provided with a fastening structure that is detachable from the reactor module (2100).

[0192] Additionally, the working fluid line (SL) can be connected to the reactor (2110) by penetrating the reactor shielding unit (2150). The reactor shielding unit (2150) may have a multi-shielding structure including a bulkhead. The working fluid line (SL) may be provided with a structure capable of penetrating the bulkhead and connecting to the reactor (2110).

[0193] The specific connection structure of the lines connecting through the reactor shielding unit (2150), including the working fluid line (SL), will be explained in detail below.

[0194] The generator (2220) can convert power generated from the steam turbine (2210) into electrical energy. The generator (2220) is connected to the rotating shaft of the steam turbine (2210) and can generate electrical energy by receiving the rotational energy of the steam turbine (2210) and rotating.

[0195] The drain module (2300) may be equipped with a drain tank (2310) and a drain shielding unit (2350).

[0196] The drain module (2300) is connected to the reactor (2110) to drain fuel material. The drain tank (2310) and the reactor (2110) are connected by a drain line (DL), and fuel material can be drained along the drain line (DL).

[0197] Fuel material may need to be discharged from the reactor (2110) during emergency operation when the reactor (2110) needs to be controlled or when operation is stopped due to a malfunction, overheating, etc. The drain module (2300) can drain the fuel material from the reactor (2110) and store it in the drain tank (2310).

[0198] In one embodiment, the drain module (2300) may be positioned below the reactor module (2100) within the hull (2002). This allows the fuel material within the reactor module (2100) to be naturally discharged into the drain module (2300) by gravity.

[0199] The drain shielding unit (2350) can shield radiation generated from fuel material stored in the drain tank (2310). The drain shielding unit (2350) can form a predetermined sealed space in which the drain tank (2310) is accommodated. In this specification, the sealed space formed by the drain shielding unit (2350) is defined as the drain section (DR).

[0200] The drain shielding unit (2350) can shield radioactive materials in the drain section (DR).

[0201] In one embodiment, the drain shielding unit (2350) may have a first drain shielding part (2351), a second drain shielding part (2352), and a third drain shielding part (2353).

[0202] The first drain shield (2351) primarily surrounds the drain tank (2310), and the second drain shield (2352) may be provided to surround the first drain shield (2351). Additionally, a third drain shield (2353) may be positioned between the first drain shield (2351) and the second drain shield (2352).

[0203] In other words, the drain shielding unit (2350) can be provided with a shielding structure substantially identical to that of the reactor shielding unit (2150). For the specific structure and shielding principle of the drain shielding unit (2350), refer to the details regarding the reactor shielding unit (2150) to be described later.

[0204] Similar to the working fluid line (SL), the drain line (DL) can also be connected to the drain tank (2310) by passing through the reactor shielding unit (2150) and the drain shielding unit (2350).

[0205] Next, the specific structure of the reactor shielding unit (2150) will be described in detail.

[0206] The reactor shielding unit (2150) may be equipped with a first reactor shielding section (2151) and a second reactor shielding section (2152).

[0207] The first reactor shield (2151) is provided to surround the reactor section (RR) and can primarily shield the reactor section (RR). The first reactor shield (2151) may have a partition of a predetermined thickness and, as a type of sealed containment container, may surround the upper, lower, and side portions of the reactor section (RR).

[0208] For example, the first reactor shield (2151) may be in the shape of a cuboid having six partitions. Alternatively, the first reactor shield (2151) may have various shapes, such as a cylindrical shape or a dome shape.

[0209] The second reactor shield (2152) is provided to surround the first reactor shield (2151) to secondarily shield the reactor (RR). The second reactor shield (2152) may have a partition of a predetermined thickness, similar to the first reactor shield (2151), and may surround the first reactor shield (2151) as a kind of sealed containment container. The shape of the second reactor shield (2152) is also not particularly limited.

[0210] In one embodiment, the second reactor shield (2152) may be spatially separated from the first reactor shield (2151).

[0211] The first reactor shield (2151) and the second reactor shield (2152) can be physically connected by a plurality of reactor fixing spacers (2154). By the reactor fixing spacers (2154), the first reactor shield (2151) can be fixed in position by floating inside the second reactor shield (2152). The plurality of fixing spacers may be connected to the entire surface of the first reactor shield (2151) or connected to a partial surface.

[0212] The first reactor shield (2151) and the second reactor shield (2152) may each be equipped with a partition wall of any material capable of shielding radioactive material. For example, the partition walls of the first reactor shield (2151) and the second reactor shield (2152) may each include stainless steel (SUS) and concrete. Alternatively, the partition walls of the first reactor shield (2151) and the second reactor shield (2152) may include carbon steel (RC carbon steel), low alloy steel, nickel alloy, lead, tungsten (Wolfram), copper, aluminum, molybdenum, titanium, zirconium, Inconel, Hastelloy, tantalum, etc.

[0213] In one embodiment, the reactor shielding unit (2150) may further comprise a third reactor shielding section (2153). The third reactor shielding section (2153) may be provided with a fluid filled in the spaced-out space formed between the first reactor shielding section (2151) and the second reactor shielding section (2152).

[0214] For example, the third reactor shield (2153) may be provided with light water (H2O) filled in the above-mentioned space. Through this, the reactor shield unit (2150) can shield neutrons generated in the reactor section (RR). Alternatively, the third reactor shield (2153) may be provided with heavy water, borated water, lithium solution, ethylene glycol-based solution, polyethylene slurry, boron slurry, barium solution, tungsten slurry, lead slurry, etc.

[0215] In summary, the reactor shielding unit (2150) can be configured with a triple shielding section around the reactor section (RR), and in particular, the first reactor shielding section (2151) and the second reactor shielding section (2152) can be made of solid partitions, and the third reactor shielding section (2153) can be made of fluid placed between the first reactor shielding section (2151) and the second reactor shielding section (2152). Through this, the reactor shielding unit (2150) can effectively shield against radiation leakage.

[0216] In another embodiment, air may be placed in the third reactor shield (2153). The air may circulate within the space between the first reactor shield (2151) and the second reactor shield (2152) and cool the reactor section (RR).

[0217] Meanwhile, as described above, a working fluid line (SL) through which a working fluid flows, a drain line (DL) through which fuel material is drained, etc., may be connected to the reactor module (2100). In an embodiment in which the reactor shielding unit (2150) has a shielding structure including one or more bulkheads, a pipe for fluid flow may be arranged to penetrate the bulkheads, and it is necessary to prevent leakage of radiation in the penetration area.

[0218] Below, embodiments of a reactor shielding unit (2150) and a pipe connection structure capable of preventing radiation leakage will be described.

[0219] FIG. 11 is a conceptual diagram illustrating the connection structure of the reactor shielding unit (2150) of FIG. 10 and the pipe (FP) penetrating it, and FIG. 12 is a conceptual diagram illustrating a modified example of the connection structure of FIG. 11.

[0220] Referring to FIGS. 11 and 12, one or more pipes (FP) may pass through the first reactor shield (2151) and the second reactor shield (2152). The first reactor shield (2151) and the second reactor shield (2152) may each have one or more through holes, and pipes (FP) may be inserted into the through holes.

[0221] In one embodiment, a sealing member (SM) may be disposed between the piping (FP) and the through hole. The sealing member (SM) disposed in the first reactor shield (2151) and the second reactor shield (2152) may each comprise the same material as the first reactor shield (2151) and the second reactor shield (2152). Additionally, the exposed surface of the sealing member (SM) may be welded along the periphery of the through hole, thereby completely sealing the through hole to block the leakage of radiation.

[0222] In one embodiment, as shown in FIG. 12, a connecting bulkhead (CP) connecting the through hole of the first reactor shield (2151) and the through hole of the second reactor shield (2152) may be disposed between the first reactor shield (2151) and the second reactor shield (2152). A pipe (FP) may pass through the connecting bulkhead (CP). As a result, the pipe (FP) can more effectively block the leakage of radiation without being exposed to the third reactor shield (2153), that is, the fluid filled in the space between the first reactor shield (2151) and the second reactor shield (2152).

[0223] In this way, the ship energy system (2010) can effectively block radiation leakage from the reactor section (RR) by means of the multi-shielding structure of the reactor shielding unit (2150) and the connection structure of the fluid flow piping. The drain shielding unit (2350) and the fluid flow piping penetrating it can also be provided with substantially the same structure.

[0224] Meanwhile, as described above, the reactor module (2100) may have a modular structure that is detachably installed within the hull (2002). Accordingly, the piping connecting the reactor module (2100) and the energy conversion unit (2200) or drain module (2300) also needs to be provided with a detachable connection structure.

[0225] Below, we will describe the piping connection structure focusing on the working fluid line (SL) that connects the reactor (2110) and the energy conversion unit (2200) by penetrating area A of FIG. 10, that is, the reactor shielding unit (2150).

[0226] Figure 13 is an enlarged view of area A of Figure 10.

[0227] Referring to FIG. 10 and FIG. 13 together, the reactor module (2100) and the energy converter (2200) can be connected by a piping unit. The piping unit can connect the reactor module (2100) and the energy converter (2200) by penetrating the reactor shielding unit (2150) and can provide a flow path for the working fluid. That is, the piping unit can be provided with the aforementioned working fluid line (SL).

[0228] The piping unit may be equipped with a first connecting pipe (FP1) and a second connecting pipe (FP2). The first connecting pipe (FP1) may extend from the reactor module (2100), and the second connecting pipe (FP2) may extend from the energy conversion unit (2200). When the first connecting pipe (FP1) and the second connecting pipe (FP2) are connected, they can function as a single pipe that connects the reactor module (2100) and the energy conversion unit (2020) and allows working fluid to flow.

[0229] In one embodiment, the first connecting pipe (FP1) and the second connecting pipe (FP2) may be connected by a pipe connecting member (PC). The first connecting pipe (FP1) and the second connecting pipe (FP2), connected by the pipe connecting member (PC), may communicate with each other so that fluid can flow.

[0230] The pipe connecting member (PC) can be provided in any structure or form that connects the end of the first connecting pipe (FP1) and the end of the second connecting pipe (FP2) to allow fluid to flow continuously. For example, the pipe connecting member (PC) may have a flange structure and be secured with bolts, etc. Additionally, the pipe connecting member (PC) may further be provided with a sealing member (not shown) for sealing.

[0231] For example, the first connecting pipe (FP1) and the second connecting pipe (FP2) can be connected by a pipe connecting member (PC) outside the reactor module (2100) as shown in FIG. 13. That is, the first connecting pipe (FP1) can be connected to the second connecting pipe (FP2) outside the reactor module (2100) by penetrating the first reactor shield (2151) and the second reactor shield (2152).

[0232] As another example, although not illustrated in the drawing, the first connecting pipe (FP1) and the second connecting pipe (FP2) can be connected by a pipe connecting member (PC) inside the reactor module (2100). That is, the first connecting pipe (FP1) can be connected in the internal space of the reactor module (2100) to the second connecting pipe (FP2), which is inserted into the interior of the reactor module (2100) by penetrating the first reactor shield (2151) and the second reactor shield (2152).

[0233] As another example, although not shown in the drawing, the first connecting pipe (FP1) and the second connecting pipe (FP2) each have their ends inserted into the first reactor shield (2151) or the second reactor shield (2152) and can be connected within the first reactor shield (2151) or the second reactor shield (2152) without a separate pipe connecting member.

[0234] In this way, the first connecting pipe (FP1) and the second connecting pipe (FP2) can be connected to each other by penetrating the reactor shielding unit (2150) which is equipped with a multi-wall structure.

[0235] Although the connection structure of the piping has been described above with respect to the working fluid line (SL) connecting the reactor module (2100) and the energy conversion unit (2200), the above description may be applied to all lines connected by penetrating at least one of the reactor shielding unit (2150) and the drain shielding unit (2350), such as the drain line (DL).

[0236] Through the above-described pipe connection structure, the ship energy system (2010) of the present invention can have the reactor module (2100) and the drain module (2300) each modularized and installed separately within the hull (2002), thereby preventing the leakage of radiation from the reactor section (RR) or the drain section (DR).

[0237] When separating a modular reactor module (2100) or drain module (2300) from the hull (2002), fluid containing radioactive material may remain in the piping connected to the reactor module (2100) or drain module (2300). Accordingly, it is necessary to safely remove the remaining fluid in the piping prior to separating the piping.

[0238] Accordingly, the ship energy system (2010) of the present invention is provided with a structure for draining residual fluid on a pipe connected to a reactor module (2100) or a drain module (2300), so that radioactive material can be safely drained.

[0239] The structure for removing residual fluid from the piping and the residual fluid drain method are described as follows, focusing on Fig. 13.

[0240] A first drain pipe (DP1) is connected to a first connecting pipe (FP1) in the reactor section (RR), which is the internal space of the reactor module (2100), and a second drain pipe (DP2) can be connected to a second connecting pipe (FP2) on the outside of the reactor module (2100).

[0241] The first drain pipe (DP1) and the second drain pipe (DP2) can each be connected to a drain treatment unit (not shown). The remaining fluid can be drained to the drain treatment unit (not shown) through the first drain pipe (DP1) and / or the second drain pipe (DP2) to be stored, treated, and discharged.

[0242] For example, a drain treatment unit (not shown) may have a predetermined storage space to store the drained residual fluid. Alternatively, the drain treatment unit (not shown) may be equipped with a filter capable of filtering radioactive materials within the residual fluid.

[0243] Although not shown in the drawing, the first drain pipe (DP1) and the second drain pipe (DP2) can each be connected to a drain pump. Residual fluid in the first connecting pipe (FP1) and the second connecting pipe (FP2) can be drained by the drain pump.

[0244] A first connecting valve (FV1) and a second connecting valve (FV2) for controlling fluid flow may be disposed in the first connecting pipe (FP1) and the second connecting pipe (FP2), respectively. The first drain pipe (DP1) and the second drain pipe (DP2) are provided between the first connecting valve (FV1) and the second connecting valve (FV2), and a first drain valve (DV1) and a second drain valve (DV2) may be disposed in the first drain pipe (DP1) and the second drain pipe (DP2), respectively.

[0245] When separating the reactor module (2100) from the hull (2002), the first connecting valve (FV1) and the second connecting valve (FV2) may be closed first. Upon closing the first connecting valve (FV1) and the second connecting valve (FV2), the fluid flow in the first connecting pipe (FP1) and the second connecting pipe (FP2) is stopped, but residual fluid may remain between the first connecting valve (FV1) and the second connecting valve (FV2).

[0246] Next, the first drain valve (DV1) and the second drain valve (DV2) are opened so that the remaining fluid can be drained to a drain treatment unit (not shown), respectively. After all the remaining fluid placed between the first connecting valve (FV1) and the second connecting valve (FV2) has been drained, the first connecting pipe (FP1) and the second connecting pipe (FP2) can be separated. In this way, the reactor module (2100) can be separated from the hull (2002) with the remaining fluid in the pipes safely removed.

[0247] As described above, the reactor module (2100) and drain module (2300), which are modularized and installed within the hull (2002), can be connected to each other in a way that allows them to be separated.

[0248] In detail, it is necessary to ensure the safety of the ship's (1') systems and personnel by discharging fuel material containing radioactive material from the hull (2002) during emergency operation when the output of the reactor (2110) needs to be controlled or when operation is stopped due to a malfunction, overheating, etc. Meanwhile, if the reactor module (2100) and the drain module (2300) are discharged together, the reactor module (2100) and the drain module (2300) may sink to the seabed due to the load of the structure, making recovery difficult.

[0249] The vessel (1') of the present invention may be configured such that, as the reactor module (2100) and the drain module (2300) are detachably connected, in the event of an emergency, only the drain module (2300) is separated and discharged from the hull (2002) while the fuel material is drained into the drain module (2300). Through this, the vessel (1') of the present invention can separate and discharge and recover the drain module (2300) containing radioactive material more quickly and efficiently.

[0250] Figure 14 is an enlarged view of area B of Figure 10.

[0251] Referring to FIG. 14, the reactor module (2100) and the drain module (2300) can be connected to each other by a connecting member (DM).

[0252] The fastening member (DM) is connected to the reactor shielding unit (2150) and the drain shielding unit (2350), respectively, to fasten the reactor module (2100) and the drain module (2300). The type and shape of the fastening member (DM) are not particularly limited, and it can be provided in any form that can structurally connect spaced-apart bulkheads, such as a bolt-nut connection structure, rivets, clamps, or brackets, and can be separated if necessary.

[0253] In one embodiment, the fastening member (DM) may have both ends connected to the second reactor shield (2152) and the second drain shield (2352), respectively, as shown in FIG. 14.

[0254] In another embodiment, although not shown in the drawing, the fastening member (DM) may have both ends penetrate the second reactor shield (2152) and the second drain shield (2352) respectively and be connected to the first reactor shield (2151) and the first drain shield (2351).

[0255] In one embodiment, the fastening member (DM) may be positioned adjacent to the reactor fixing spacer (2154) and the drain fixing spacer (354). This allows the fastening member (DM) to more stably fasten the reactor shielding unit (2150) and the drain shielding unit (2350).

[0256] In one embodiment, the fastening member (DM) may be provided with an end connected to the drain shielding unit (2350) so as to be detachable in case of emergency. When separate discharge of the drain module (2300) is required, the end of the fastening member (DM) coupled to the drain shielding unit (2350) may be detached from the drain shielding unit (2350) to release the connection between the reactor module (2100) and the drain module (2300).

[0257] In another embodiment, the fastening member (DM) may be provided with an end connected to the reactor shielding unit (2150) so as to be detachable in case of emergency. When separate discharge of the drain module (2300) is required, the end of the fastening member (DM) coupled to the reactor shielding unit (2150) may be detached from the reactor shielding unit (2150) to release the connection between the reactor module (2100) and the drain module (2300).

[0258] FIG. 15 is a drawing showing the state in which the drain module (2300) of FIG. 10 is separated and discharged from the hull (2002), and FIG. 16 and FIG. 17 are drawings exemplarily showing the operating state of a vessel (1') separating and discharging the drain module (2300).

[0259] Referring to FIGS. 15 to 17, the drain module (2300) can be released from the reactor module (2100) and separated from the hull (2002).

[0260] In the event of an emergency operation such as a failure or overheating of the reactor (2110), the fuel material can be drained from the reactor module (2100) to the drain module (2300). The ship (1') of the present invention can ensure the safety of the systems and personnel within the ship by separating and discharging the drain module (2300), which stores the fuel material containing radioactive material, from the hull (2002) during the above emergency operation.

[0261] To this end, a lower slide door (LSD) may be provided in the recess (RC) of the hull (2002). The lower slide door (LSD) may have a structure that allows it to slide and open / close.

[0262] In case of emergency, when fuel material is drained into the drain module (2300), at least one side of the connecting member (DM) connecting the reactor module (2100) and the drain module (2300) may be separated, and the connection between the reactor module (2100) and the drain module (2300) may be released. The drain line (DL) connecting the reactor (2110) and the drain tank (2310) may also be disconnected as the pipe connecting member (not shown) is separated.

[0263] In this state, when the lower slide door (LSD) slides open, the drain module (2300) can naturally descend by gravity as shown in FIG. 16 and be discharged outside the hull (2002). That is, the drain module (2300) can be discharged into the sea through a recess (RC) formed concavely between a pair of propellers (PP) in the hull (2002).

[0264] After the drain module (2300) is discharged into the sea, the vessel (1') can continue to operate as shown in FIG. 17. As the drain module (2300) is discharged through a recess (RC) that is concavely recessed from the outer surface of the hull (2002), the vessel (1') can continue to operate without interference between the discharged drain module (2300) and the hull (2002). The drain module (2300) discharged into the sea can be recovered to land using separate equipment.

[0265] In summary, the vessel (1') of the present invention can rapidly discharge a drain module (2300) containing radioactive material outside the hull (2002) in case of emergency and operate, and the discharged drain module (2300) can subsequently be recovered to land.

[0266] FIG. 18 is a drawing illustrating a ship energy system according to another embodiment of the present invention.

[0267] The ship energy system of FIG. 18 differs from the ship energy system (2010) of FIG. 10 in that it is equipped with two ship reactor systems. Accordingly, the following description will focus on the differences mentioned above, and other detailed configurations, piping connection structures, etc. will be described by referring to FIG. 10 and the above.

[0268] Referring to FIG. 18, the ship of the present invention may be equipped with two ship energy systems.

[0269] The vessel (1') of the present invention can operate using propulsion produced from energy resulting from a nuclear fission reaction occurring in a nuclear reactor. Accordingly, the vessel (1') of the present invention needs to duplicate the ship energy system including the nuclear reactor to prepare for emergency situations such as a failure of the nuclear reactor, that is, to secure redundancy.

[0270] The ship of the present invention is equipped with a redundant ship energy system, and within the hull (2002), two reactor modules and two drain modules may each be provided.

[0271] The two ship energy systems equipped by the ship of the present invention are defined as the first ship energy system (2010A) and the second ship energy system (2010B), respectively. The reactor modules equipped by the first ship energy system (2010A) and the second ship energy system (2010B) are defined as the first reactor module (2100A) and the second reactor module (2100B), respectively, and the drain module connected to the first reactor module (2100A) is defined as the first drain module (2300A), and the drain module connected to the second reactor module (2100B) is defined as the second drain module (2300B).

[0272] The first reactor module (2100A), the second reactor module (2100B), the first drain module (2300A), and the second drain module (2300B) can each be modularized and installed within the hull (2002) or separated from the hull (2002) for maintenance, and can be separated and discharged from the hull (2002) in case of emergency.

[0273] In one embodiment, the first ship energy system (2010A) and the second ship energy system (2010B) can each provide power to at least one of the first propeller (PP1) and the second propeller (PP2).

[0274] For example, during normal operation of the vessel (1'), the first vessel energy system (2010A) can provide power to the first propeller (PP1), and the second vessel energy system (2010B) can provide power to the second propeller (PP2). Meanwhile, in the event of emergency operation, such as a failure of either the first vessel energy system (2010A) or the second vessel energy system (2010B), the other can provide power to both the first propeller (PP1) and the second propeller (PP2). Through this, the operation of the vessel (1') can be maintained even in the event of an emergency, such as a failure or shutdown of the reactor.

[0275] The first ship energy system (2010A) and the second ship energy system (2010B) can be positioned on the upper part of the recess (RC) of the hull (2002). In this way, in the event of a failure of either the first ship energy system (2010A) or the second ship energy system (2010B), the first drain module (2300A) or the second drain module (2300B) corresponding to either one can be separated and discharged outside the hull (2002) through the lower slide door (LSD). For the separation and discharge of the first drain module (2300A) and the second drain module (2300B) and the operation of the ship, the above-described details regarding FIG. 15, etc., will be referenced.

[0276] A ship energy system according to another embodiment of the present invention and a ship including the same have a reactor module and a drain module separatedly arranged within the hull, so that in the event of an emergency, the drain module draining the fuel material can be rapidly separated and discharged to the outside of the hull, thereby ensuring safety on board. In addition, a ship energy system according to another embodiment of the present invention and a ship including the same can ensure operational stability of the ship by duplicating the ship energy system.

[0277]

[0278] Hereinafter, a ship energy system (3020) according to another embodiment of the present invention and a ship (1``) including the same will be described.

[0279] FIG. 19 is a drawing illustrating a vessel (1``) according to another embodiment of the present invention.

[0280] Referring to FIG. 19, a ship (1``) according to another embodiment of the present invention may include a hull (3010) and a ship energy system (3020).

[0281] The hull (3010) forms the exterior of the ship (1'') and can be propelled by receiving driving force from the ship energy system (3020).

[0282] For example, the hull (3010) can receive power from the energy conversion unit (3200) of the ship energy system (3020) and can operate using the power received from the energy conversion unit (3200) as propulsion.

[0283] The hull (3010) may be equipped with an engine room (3021), and a ship energy system (3020) may be placed inside the engine room (3021), and a sealed area may be formed inside the engine room (3021).

[0284] In one embodiment, the ship energy system (3020) can be interpreted as a nuclear propulsion system for ships.

[0285] In one embodiment, the engine room (3021) may be located below the deck of the hull (3010).

[0286] Referring to FIG. 19, the ship energy system (3020) may include an energy generation unit (3100), an energy conversion unit (3200), a drain tank room (3300), and a waste storage unit (3400).

[0287] At least one of the energy generation unit (3100), energy conversion unit (3200), drain tank room (3300), and waste storage unit (3400) may be located inside the engine room (3021).

[0288] For example, the energy generation unit (3100), energy conversion unit (3200), drain tank room (3300), and waste storage unit (3400) can all be placed inside the engine room (3021).

[0289] Referring to FIG. 19, the waste storage unit (3400) can store radioactive waste discharged or leaked from the ship energy system (3020).

[0290] Radioactive waste stored in the waste storage unit (3400) can be discharged to the storage unit (WS), for example, radioactive waste stored in the waste storage unit (3400) can be discharged to the storage unit (WS) through the main discharge line (MEL).

[0291] Radioactive waste discharged or leaked from the ship energy system (3020) while the ship (1``) is in operation can be stored in a waste storage unit (3400), and while the ship (1``) is docked at a port, the radioactive waste stored in the waste storage unit (3400) can be discharged to a storage unit (WS) located at the port.

[0292] Specifically, when the vessel (1'') is docked at a port, the waste storage unit (3400) and the storage unit (WS) can be connected to each other through a main discharge line (MEL), thereby allowing the radioactive waste collected in the waste storage unit (3400) during the operation of the vessel (1'') to be safely transferred to the storage unit (WS) located at the port.

[0293] The main discharge line (MEL) can be composed of various devices that can selectively connect the waste storage unit (3400) and the storage unit (WS), for example, the main discharge line (MEL) can be composed of pipes, hoses, multiple pipes, etc.

[0294] FIG. 20 is a schematic diagram illustrating the ship energy system (3020) shown in FIG. 19.

[0295] Referring to FIG. 20, the energy generation unit (3100) generates thermal energy using nuclear power and may include a nuclear reactor (3110) and a nuclear reactor shielding member (3120).

[0296] The energy generation unit (3100) can be located inside the engine room (3021) of the ship (1``).

[0297] The energy generation unit (3100) can be located above the drain tank room (3300) inside the engine room (3021).

[0298] For example, the energy generation unit (3100) may be located higher than the floor of the engine room (3021) than the drain tank room (3300).

[0299] The energy generation unit (3100) can be located above the waste storage unit (3400) inside the engine room (3021).

[0300] For example, the energy generation unit (3100) may be located higher than the waste storage unit (3400) on the floor of the engine room (3021).

[0301] A nuclear reactor (3110) can generate thermal energy using nuclear power. For example, the nuclear reactor (3110) can generate high-temperature heat by nuclear fission of nuclear fuel such as uranium 235, and inside the nuclear reactor (3110), control rods can control the number of neutrons to control the speed of the nuclear fission chain reaction.

[0302] A cooling system may be placed around the nuclear fuel. The coolant flowing through the cooling system can reduce the temperature of the nuclear fuel.

[0303] Referring to FIG. 20, the reactor shielding member (3120) of the present invention accommodates a reactor (3110) inside and can be located inside an engine room (3021).

[0304] The reactor shielding member (3120) can form the exterior of the energy generating unit (3100), and the reactor shielding member (3120) can be made of various materials capable of blocking gamma rays and / or neutrons generated in the reactor (3110) from being emitted to the outside.

[0305] For example, the reactor shielding member (3120) may include stainless steel or steel material.

[0306] The reactor shielding member (3120) may include a first reactor shielding part (3121), a second reactor shielding part (3122), a third reactor shielding part (3123), and a first support part (3124), and a description related thereto will be made in detail in the description of FIG. 22.

[0307] The energy generation unit (3100) can be connected to the waste storage unit (3400). Specifically, the interior of the energy generation unit (3100) can be connected to the interior of the waste storage unit (3400) through the first discharge line (EL1).

[0308] As a result, radioactive waste discharged or leaked from the energy generation unit (3100) is discharged to the waste storage unit (3400) through the first discharge line (EL1), so that radioactive waste can be stably stored in the waste storage unit (3400) during the operation of the vessel (1'').

[0309] Referring to FIG. 20, the energy conversion unit (3200) receives thermal energy from the energy generation unit (3100) and provides power to the ship (1''), and may include a steam turbine (3210) and a generator (3220).

[0310] The steam turbine (3210) can produce kinetic energy using a working fluid supplied from an energy generation unit (3100), wherein the working fluid can be interpreted as a fluid containing thermal energy generated in a nuclear reactor (3110).

[0311] The steam turbine (3210) can be connected to the energy generation unit (3100) through a supply line (SL), and the working fluid can flow from the energy generation unit (3100) to the steam turbine (3210) through the supply line (SL).

[0312] The generator (3220) can convert the above kinetic energy into electrical energy.

[0313] A generator (3220) is connected to the rotating shaft of the steam turbine (3210), and the shaft of the generator (3220) can generate electricity by receiving the rotational energy of the steam turbine (3210) and rotating.

[0314] The energy conversion unit (3200) can be connected to the waste storage unit (3400). Specifically, the interior of the energy conversion unit (3200) can be connected to the interior of the waste storage unit (3400) through a third discharge line (EL3).

[0315] As a result, radioactive waste discharged or leaked from the energy conversion unit (3200) is discharged to the waste storage unit (3400) through the third discharge line (EL3), thereby allowing radioactive waste to be stably stored in the waste storage unit (3400) during the operation of the vessel (1'').

[0316] Referring to FIG. 20, the drain tank room (3300) stores molten salt discharged from the energy generation unit (3100) and may include a drain tank (3310) and a drain shielding member (3320).

[0317] The drain tank (3310) is connected to the energy generation unit (3100) or the reactor (3110) and may be a container or tank that receives molten salt discharged from the reactor (3110).

[0318] The drain tank (3310) can be connected to the reactor (3110), for example, the drain tank (3310) can be connected to the reactor (3110) through a drain line (DL).

[0319] The drain shielding member (3320) accommodates the drain tank (3310) and can form an internal area where the drain tank (3310) is located as a sealed area.

[0320] The drain shielding member (3320) can be connected to the reactor shielding member (3120). For example, the drain shielding member (3320) can be detachably connected to the reactor shielding member (3120).

[0321] In situations where the cooling system of the reactor (3110) is damaged and a large amount of high-temperature radioactive molten salt or coolant leaks out, causing the entire interior of the reactor shielding member (3120) to be contaminated, or where a fire occurs in the energy generation unit (3100), or where the drain tank (3310) becomes saturated and the drain tank (3310) needs to be replaced quickly, the drain shielding member (3320) is separated from the reactor shielding member (3120), thereby having the effect of quickly separating the drain tank room (3300) from the energy generation unit (3100).

[0322] The drain tank room (3300) and the energy generation unit (3100) may be placed inside the engine room (3021), and the drain tank room (3300) may be located closer to the floor of the engine room (3021) than the energy generation unit (3100).

[0323] For example, the upper surface of the drain tank room (3300) can be detachably connected to the lower surface of the energy generation unit (3100), and the other side opposite to the one side of the drain tank room (3300) connected to the energy generation unit (3100) can be connected to the floor of the engine room (3021).

[0324] The drain tank room (3300) can be installed at the bottom of the engine room (3021), and the energy generation unit (3100) can be located at the top of the drain tank room (3300).

[0325] As a result, the energy generation unit (3100) and the drain tank room (3300) are connected so as to be separable from each other, and at the same time, the molten salt discharged from the reactor (3110) can be efficiently discharged into the drain tank (3310) by gravity.

[0326] The drain shielding member (3320) can form the exterior of the drain tank room (3300), and the drain shielding member (3320) can be made of various materials capable of blocking gamma rays and / or neutrons leaking from the drain tank (3310) or drain line (DL) from being emitted to the outside.

[0327] For example, the drain shielding member (3320) may include stainless steel or steel material.

[0328] The drain shielding member (3320) may include a first drain shielding part (3321), a second drain shielding part (3322), a third drain shielding part (3323), and a second support part (3324), and a description related thereto will be made in detail in the description regarding FIG. 23.

[0329] The drain tank room (3300) can be connected to the waste storage unit (3400). Specifically, the interior of the drain tank room (3300) can be connected to the interior of the waste storage unit (3400) through a second discharge line (EL2).

[0330] As a result, radioactive waste discharged or leaked from the drain tank room (3300) is discharged into the waste storage unit (3400) through the second discharge line (EL2), thereby allowing radioactive waste to be stably stored in the waste storage unit (3400) during the operation of the vessel (1'').

[0331] FIG. 21 is a drawing illustrating the ship energy system (3020) shown in FIG. 20 in more detail.

[0332] Referring to FIG. 21, the waste storage unit (3400) stores radioactive waste discharged from at least one of the energy generation unit (3100), energy conversion unit (3200), and drain tank room (3300), and may include a storage tank unit (3410), a housing unit (3420), and a waste shielding unit (3430).

[0333] The waste storage unit (3400) can be located inside the engine room (3021).

[0334] For example, the outer surface of the waste storage unit (3400) can come into surface contact with the bottom of the engine room (3021).

[0335] The energy generation unit (3100) and the waste storage unit (3400) can be spaced apart from each other inside the engine room (3021).

[0336] The drain tank room (3300) and the waste storage unit (3400) can be spaced apart from each other inside the engine room (3021).

[0337] The energy generation unit (3100) can be located higher than the waste storage unit (3400) on the floor of the engine room (3021).

[0338] As a result, radioactive waste discharged or leaked from the energy generation unit (3100) can be naturally discharged to the waste storage unit (3400) by its own gravity, even without a separate pump or high pumping power.

[0339] The drain tank room (3300) can be located higher than the floor of the engine room (3021) than the waste storage section (3400).

[0340] As a result, radioactive waste discharged or leaked from the drain tank room (3300) can be naturally discharged into the waste storage unit (3400) by its own gravity, even without a separate pump or high pumping power.
