[0047] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0048] It should be noted that solution-type reactors have been highly valued in related technologies due to their advantages such as good inherent safety, simple production process, less radioactive waste, small impact on the environment, low investment and low production cost. In addition, the use of solution-type reactors to extract medical radioactive nuclides is also a relatively economical and effective method at this stage.

[0049] A solution-type medical isotope reactor (SMR) is a homogeneous solution-type reactor fueled by aqueous uranyl nitrate solution. The total 235U loading is approximately 6.2 kg, with a uranium concentration of approximately 46 gU / L. The effective volume of the fuel solution is approximately 135 L, and the reactor is designed to operate at a rated power of approximately 50 kW to 200 kW. A SMR typically comprises a reactor vessel 100' and multiple process systems, including at least an emergency discharge system 200', a fuel solution transfer and temporary storage system 300', a gas recombination system 400', a primary cooling water system, a secondary cooling water system, a pool water purification and cooling system, a nitrogen purge system, and an acid replenishment system.

[0050] Among them, the emergency discharge system 200' is used to quickly discharge the fuel solution in the reactor vessel 100' to the emergency discharge tank 210' in the event of failure of the reactor protection system, so as to realize emergency shutdown; the fuel solution transfer and temporary storage system 300' is used to carry out the transportation of the fuel solution, so that the fuel solution can be loaded and unloaded between the fuel temporary storage tank 310' and the reactor vessel; the gas recombination system 400' is led out from the upper air cavity of the reactor vessel 100', and is used to discharge the fission gas in the reactor vessel 100', so that the hydrogen and oxygen generated in the radiolysis process are catalytically recombinated into water in time, and is used to cooperate with the acid replenishment system to automatically replenish nitric acid solution to the reactor core to ensure that the hydrogen concentration does not exceed the limit value, and the volume and acidity of the core fuel solution are controlled within the allowable range, so that the reactor can operate safely and stably; the primary cooling water system is used to transfer the heat generated by the reactor core Reliable and effective degassing to ensure that the fuel solution temperature in the reactor core is within the allowable range; the secondary cooling water system is used to transfer heat from the primary cooling water system to the heat sink; the pool water purification and cooling system is used to remove impurities in the cooling water in the reactor pool and the temporary storage tank pool, the aforementioned impurities include soluble ionic impurities and insoluble solid impurities, so as to maintain the water chemical indicators within the allowable range, and is used to adjust the cooling water temperature of the reactor pool and the temporary storage tank pool; the nitrogen purge system is used to respond to the hydrogen risk in the reactor vessel 100' and other related equipment in the short or long term under accident conditions or design expansion conditions, and to maintain the hydrogen concentration in the reactor vessel 100' and other related equipment below the ignition value by controlling the nitrogen purge flow rate within a certain period of time; the acid replenishment system is used to replenish nitric acid to the reactor core to maintain the acidity of the core fuel solution within the allowable range.

[0051] In actual applications, each of the aforementioned systems will usually include at least one process equipment for performing the corresponding system functions and at least one set of pipeline equipment for transmitting fluid to the corresponding process equipment. The aforementioned pipeline equipment may include pipe fittings and may also include valve components or pump components arranged on the aforementioned pipe fittings. Taking the aforementioned emergency discharge system 200' as an example, the emergency discharge system 200' may include an emergency discharge tank 210', an emergency discharge pipe 220' and an emergency discharge valve 230', wherein the emergency discharge tank 210' is used to accommodate the fuel solution discharged from the reactor vessel 100' or the fuel temporary storage tank 310'. Accordingly, the emergency discharge tank 210' can be regarded as a process equipment of the emergency discharge system 200'. The emergency discharge tank 210' can be connected to the reactor vessel 100' and the fuel temporary storage tank 310' through the emergency discharge pipe 220'. The emergency discharge valve 230' is used to control the on-off state of the emergency discharge pipe 220'. Accordingly, the emergency discharge pipe 220' and the emergency discharge valve 230' can be regarded as pipeline equipment of the emergency discharge system 200'. Taking the aforementioned fuel solution transfer and temporary storage system 300' as an example, the fuel solution transfer and temporary storage system 300' may include a fuel temporary storage tank 310', a first delivery pipe 320', a second delivery pipe 330', a third delivery pipe 340' and a fourth delivery pipe 350'. The fuel temporary storage tank 310' is used to temporarily store the fuel solution and can be regarded as a process equipment of the fuel solution transfer and temporary storage system 300'. The aforementioned first delivery pipe 320' and the aforementioned second delivery pipe 330' are used to connect between the fuel temporary storage tank 310' and the reactor vessel 100', and are used to guide the fuel solution in the reactor vessel 100' to the fuel tank 310'. The fuel temporary storage tank 310' is used to guide the fuel solution in the fuel temporary storage tank 310' to the reactor vessel 100'. The third delivery pipe 340' and the fourth delivery pipe 350' are used to connect between the fuel temporary storage tank 310' and the isotope extraction system, and are used to guide the fuel solution in the isotope extraction system to the fuel temporary storage tank 310' and to guide the fuel solution in the fuel temporary storage tank 310' to the isotope extraction system, respectively. Therefore, the first delivery pipe 320', the second delivery pipe 330', the third delivery pipe 340', and the fourth delivery pipe 350' can be regarded as pipeline equipment of the fuel solution transfer and temporary storage system 300'.Taking the aforementioned gas recombination system 400' as an example, the gas recombination system 400' may include an oxyhydrogen recombiner 410', a jet pump 420', a cooling water tank 430', a fifth delivery pipe 440', and a sixth delivery pipe 450'. The oxyhydrogen recombiner 410', the jet pump 420', and the cooling water tank 430' are sequentially connected and can be considered process equipment of the gas recombination system 400'. The fifth delivery pipe 440' is connected between the oxyhydrogen recombiner 410' and the top exhaust pipe of the reactor vessel 100' to receive exhaust gas from the reactor vessel 100'. The sixth delivery pipe 450' is connected between the cooling water tank 430' and the top air inlet pipe of the reactor vessel 100' to supply gas into the reactor vessel 100'. Accordingly, the fifth delivery pipe 440' and the sixth delivery pipe 450' can be considered piping equipment of the gas recombination system 400'. The equipment of the remaining systems is not listed here one by one.

[0052] The aforementioned emergency discharge system 200', fuel solution transfer and temporary storage system 300', and gas recombination system 400' are typically directly connected to the reactor vessel 100' and come into direct contact with the highly radioactive fuel solution or fission gas during operation. They can be considered the first layer of shielding and containment for the highly radioactive medium. Accordingly, most of the process equipment and piping equipment contained within these systems are highly radioactive, resulting in high dose levels in nearby areas, making them generally inaccessible to maintenance personnel. This significantly reduces the lifespan of sensitive materials in these areas. Consequently, these systems can be considered the highly radioactive systems of a solution-type medical isotope reactor. The fluid media transported by the aforementioned primary cooling water system, secondary cooling water system, pool water purification and cooling system, nitrogen purge system, and acid replenishment system do not carry high radioactivity. In actual applications, the connection points between the aforementioned five systems and the aforementioned high-radioactivity system are usually equipped with isolation valves such as check valves and stop valves. Therefore, the primary cooling water system, secondary cooling water system, pool water purification and cooling system, nitrogen purge system, and acid replenishment system can be regarded as low-radioactivity systems of the solution-type medical isotope reactor.

[0053] Due to the different radioactivity levels and environmental impacts of the aforementioned high-radioactivity systems and low-radioactivity systems during operation, there are differences in the engineering operation, maintenance and monitoring requirements between the aforementioned high-radioactivity systems and low-radioactivity systems. In addition, with the increasing demand for medical isotope production, it is often necessary to arrange dual or multiple stacks within the plant. In addition, given the limited space in the plant, the layout of the plant used to accommodate solution-type medical isotope stacks is increased.

[0054] In view of this, if Figures 1 to 5As shown, according to an embodiment of the present disclosure, a plant structure 100 for a solution-type medical isotope reactor is proposed, comprising: a building body 110, which is formed with a first indoor space 101 and a second indoor space 102, wherein the first indoor space 101 is used to accommodate a first type of equipment of the solution-type medical isotope reactor, and the second indoor space 102 is used to accommodate a second type of equipment of the solution-type medical isotope reactor, wherein the radioactivity level of the first type of equipment is higher than that of the second type of equipment; a first shielding cover plate 130 and a second shielding cover plate 140, both of which are arranged on the building body 110 The top of the building body 110 is provided with a first through-port and a second through-port, the first through-port is connected to the first indoor space 101, and the second through-port is connected to the second indoor space 102, the first shielding cover 130 is used to open or cover the first through-port, and the second shielding cover 140 is used to open or cover the second through-port, and both the first through-port and the second through-port are used to pass the sling; wherein, in the projection plane perpendicular to the height direction of the building body 110, the orthographic projection of part of the first indoor space 101 and the orthographic projection of part of the second indoor space 102 coincide with each other.

[0055] The plant structure 100 for a solution-type medical isotope reactor provided herein includes the aforementioned building body 110, a first shielding cover plate 130, and a second shielding cover plate 140. In practical applications, the plant structure 100 can be used to house the solution-type medical isotope reactor, providing a storage space for the reactor. The building body 110 includes a first indoor space 101 and a second indoor space 102, each of which is used to house first-type and second-type equipment of the solution-type medical isotope reactor. The radioactivity level of the first-type equipment during operation is higher than that of the second-type equipment. Thus, by utilizing different indoor spaces to house the two types of equipment, the plant structure 100 facilitates separate operation, maintenance, and monitoring of the first and second types of equipment during operation of the solution-type medical isotope reactor, thereby improving the maintenance convenience of the solution-type medical isotope reactor and facilitating radioactivity control of the solution-type medical isotope reactor.

[0056] The top of the building body 110 is provided with a first through-hole and a second through-hole for passing a lifting device. The first through-hole and the second through-hole are connected to the first indoor space 101 and the second indoor space 102, respectively. In actual use, the first and second types of equipment can be easily loaded into or removed from the first indoor space 101 and the second indoor space 102 using a lifting device, thereby improving the convenience of equipment maintenance and replacement of the solution-type medical isotope reactor. The first shielding cover 130 and the second shielding cover 140 are respectively used to cover or open the first through-hole and the second through-hole. When equipment maintenance is required in the first indoor space 101 or the second indoor space 102, the corresponding shielding cover can be opened to facilitate the passage of the lifting device. When equipment maintenance is not required, the first and second shielding covers 130 and 140 can be used to cover the first and second through-holes, respectively, to ensure a stable internal environment of the building body 110 and reduce the impact on the external environment, thereby improving the operational stability and safety of the solution-type medical isotope reactor.

[0057] Moreover, in the projection plane perpendicular to the height direction of the building body 110, the orthographic projection of part of the first indoor space 101 and the orthographic projection of part of the second indoor space 102 coincide with each other, so that in the height direction of the building body 110, part of the first indoor space 101 and part of the second indoor space 102 can form an overlapping relationship, and accordingly, another part of the first indoor space 101 and another part of the second indoor space 102 can form a staggered relationship, that is, part of the first indoor space 101 and part of the second indoor space 102 correspond to the same horizontal area, and the horizontal area corresponding to another part of the first indoor space 101 is different from the horizontal area corresponding to another part of the second indoor space 102. On the one hand, the space utilization rate in the height direction of the building body 110 can be improved, so that when the volume of the building body 110 is constant, it is beneficial to reduce the footprint of the building body 110, facilitate the construction of multiple aforementioned factory structures 100 in the factory area, and provide facilities for implementation in the factory area. On the other hand, it is understandable that there is a connection relationship between some of the first-type equipment and some of the second-type equipment. Accordingly, the first-type equipment and the second-type equipment with a relatively direct connection relationship can be respectively arranged in the first indoor space 101 and the second indoor space 102 corresponding to the same horizontal area, so as to facilitate the connection of the first-type equipment and the second-type equipment with a relatively direct connection relationship through through-the-ground installation or through-the-wall installation, thereby improving the equipment installation convenience of the solution-type medical isotope stack. In addition, the first-type equipment and the second-type equipment with no connection relationship or a relatively indirect connection relationship can be respectively arranged in the first indoor space 101 and the second indoor space 102 corresponding to different horizontal areas, thereby increasing the spatial position difference between the first-type equipment and the second-type equipment with no connection relationship or a relatively indirect connection relationship, reducing the radioactive impact between the equipment, and improving the operation stability and safety of the solution-type medical isotope stack.

[0058] In summary, the plant structure 100 for a solution-type medical isotope reactor provided in the embodiment of the present disclosure can provide targeted accommodation space for equipment with different radioactivity levels in the solution-type medical isotope reactor in actual applications, facilitate the operation, maintenance, and monitoring of equipment with high and low radioactivity levels, and is beneficial for improving the installation convenience and operational safety of the solution-type medical isotope reactor while accommodating the solution-type medical isotope reactor. It is also beneficial for reducing the floor space occupied by the building body 110 within the plant area and improving the utilization rate of the internal space of the plant area.

[0059] It should be noted that, in order to facilitate the display of the internal structure of the plant structure 100 for the solution-type medical isotope reactor, Figure 1 The aforementioned factory building structure 100 shown in FIG. 1 has one side wall of the building body 110 hidden.

[0060] It is understandable that, in actual applications, the equipment in a solution-type medical isotope reactor can be classified according to the system to which each device belongs and the degree of contact between the corresponding equipment and the highly radioactive fuel solution or fission gas to determine the aforementioned first type of equipment or second type of equipment; for example, the process equipment and piping equipment included in the aforementioned each high-radioactive system can be classified as first type of equipment, and the process equipment and piping equipment included in the aforementioned low-radioactive system can be classified as second type of equipment.

[0061] It should be noted that each of the aforementioned high-radioactivity systems may also include auxiliary equipment in addition to the aforementioned process equipment and piping equipment, such as a drive device 520' for driving the electric valve body 510' or the electric pump body, a control device 620' for adjusting the opening or open / close state of the manual valve body 610', etc. The aforementioned auxiliary equipment can be classified based on the radioactivity level during its actual use. For example, if the radioactivity level of the auxiliary equipment of the high-radioactivity system is low, it can also be classified as the aforementioned second-type equipment. In other words, not all equipment in the high-radioactivity system is first-type equipment, and the specific classification can also be determined based on the actual radioactivity level of the equipment.

[0062] Taking the aforementioned high-radioactivity system as an example, the aforementioned high-radioactivity system may include a high-radioactivity electric valve 500', a high-radioactivity manual valve 600', and a high-radioactivity pump 700'. The number of the aforementioned high-radioactivity electric valve 500', high-radioactivity manual valve 600', and high-radioactivity pump 700' may be more than one; the high-radioactivity electric valve 500' may include an electric valve body 510' and a driving device 520'. The aforementioned electric valve body 510' and the aforementioned driving device 520' are connected, and the driving device 520' is used to drive the electric valve body 510' to operate, so that the electric valve body 510' cuts off or conducts the pipe in which it is located, or adjusts the flow of the corresponding pipe; the high-radioactivity manual valve 600' may include a manual valve body 610' and a control device 620'. The aforementioned manual valve body 610' and the aforementioned control device 620' are connected, and the control device 620' is used to adjust the opening of the manual valve body 610'. The manual valve body 610' can be adjusted to a certain degree or open or closed state, so that the manual valve body 610' can cut off or conduct the pipe in which it is located, or adjust the flow rate of the corresponding pipe; accordingly, the electric valve body 510' and the manual valve body 610' are used to circulate highly radioactive fuel solution or fission gas, and have a high radioactivity level, and can be classified as the first type of equipment mentioned above; the driving device 520' and the operating device 620' do not directly contact the fuel solution or fission gas, and have a low radioactivity level, and can be classified as the second type of equipment mentioned above; the high-level radioactive pump 700' may include a pump body and a driving motor, the pump body being connected to the driving motor, the driving motor being used to drive the pump body to operate, and the pump body being used to drive the highly radioactive fuel solution or fission gas to flow in the corresponding pipe. Similarly, the pump body can be classified as the first type of equipment mentioned above, and the driving motor can be classified as the second type of equipment mentioned above.

[0063] It is understood that the aforementioned valve components may include the aforementioned electric valve body 510' and the aforementioned manual valve body 610'; the aforementioned pump components may include the aforementioned pump body; and the aforementioned auxiliary equipment may include the aforementioned drive device 520', the control device 620', and the drive motor. The aforementioned electric valve body 510' may be, but is not limited to, an electrically controlled valve body or a solenoid valve body; the aforementioned drive device 520' may be, but is not limited to, a valve head electrical assembly; and the aforementioned control device 620' may be, but is not limited to, a handwheel.

[0064] like Figure 1 and Figure 2As shown, in the case where the high-pressure electric valve 500' and the high-pressure manual valve 600' are suitable for installation through the ground or through the wall, based on the above-mentioned setting of the building body 110, the high-pressure electric valve 500' can be installed through the ground or wall between the first indoor space 101 and the second indoor space 102, so that the electric valve body 510' and the manual valve body 610' are located in the first indoor space 101, and the driving device 520' and the operating device 620' are located in the second indoor space 102; In cases where the high-pressure electric valve 500' and the high-pressure manual valve 600' are not suitable for through-the-ground or through-the-wall installation, such as the emergency discharge valve 230' of the emergency discharge system 200', the high-pressure electric valve 500' and the high-pressure manual valve 600' can be arranged as a whole in the first indoor space 101. It will be understood that if the high-pressure electric valve 500' and the high-pressure manual valve 600' include structures made of sensitive materials, the entire device or sensitive parts can be shielded or specially designed to extend the service life of the device and reduce maintenance frequency.

[0075] In this technical solution, the first indoor space 101 may include the aforementioned reactor water pool 1011, the temporary storage tank water pool 1012, and the gas circuit room 1013. Based on the aforementioned arrangement, the plant structure 100 for the solution-type medical isotope reactor can utilize the reactor water pool 1011 and the temporary storage tank water pool 1012 to respectively accommodate the aforementioned reactor vessel 100' and at least part of the fuel solution transfer and temporary storage system 300', and respectively accommodate cooling water for cooling the aforementioned reactor vessel 100' and cooling water for cooling the aforementioned fuel temporary storage tank 310', so as to ensure the installation stability and operational reliability of the reactor vessel 100' and the fuel solution transfer and temporary storage system 300', and can utilize the aforementioned The gas circuit room 1013 accommodates at least a portion of the aforementioned gas composite system 400'. Since the gas circuit room 1013 is connected to the aforementioned reactor water pool 1011 and the aforementioned temporary storage tank water pool 1012, the spatial continuity of the first indoor space 101 is improved, and it is convenient to connect the gas composite system 400' to the aforementioned reactor vessel 100', thereby improving the installation convenience of the gas composite system 400'. The aforementioned first through port is connected to the aforementioned gas circuit room 1013, thereby facilitating the maintenance of equipment in the gas circuit room 1013.

[0076] It can be understood that the aforementioned first direction can be a horizontal direction, for example, it can be a length direction or a width direction of the building body 110.

[0079] In some feasible examples, in the projection plane perpendicular to the height direction of the building body 110, the orthographic projection of the first through port and the orthographic projection of the reactor pool 1011 at least partially overlap, thereby facilitating the hoist to enter the reactor pool 1011 through the first through port and the air circuit room 1013 to hoist the reactor vessel 100' out for maintenance or install the reactor vessel 100' into the reactor pool 1011.

[0080] In some feasible examples, the inner wall of the building body 110 is provided with a first embedded part and a second embedded part, wherein a portion of the first embedded part is located within the aforementioned reactor water pool 1011, and a portion of the second embedded part is located within the temporary storage tank pool 1012.

The second embedded part is located on the inner bottom wall of the building body 110, which facilitates the building body 110 to more stably support the temporary fuel storage tank 310'.

[0081] In some feasible examples, the inner wall of the building body 110 corresponding to the reactor water pool 1011 and the inner wall corresponding to the aforementioned temporary tank water pool 1012 are both provided with stainless steel cladding.

[0082] like Figure 1 、 Figure 2 and Figure 4 As shown, in some examples, the first indoor space 101 also includes a first equipment room 1014, which is located in the second-floor area 110b, and the first equipment room 1014 is arranged along the first direction between the reactor water pool 1011 and the temporary storage tank water pool 1012; the second indoor space 102 includes a maintenance room 1021, which is located in the third-floor area 110c, and the first equipment room 1014 and the maintenance room 1021 are arranged correspondingly along the height direction of the building body 110, and the second through port is connected to the maintenance room 1021.

This allows auxiliary equipment with relatively low radioactive levels to be located within the aforementioned maintenance room 1021, and the aforementioned valve components and pump components with relatively high radioactive levels to be located within the aforementioned first equipment room 1014. This facilitates docking of the hoist with the aforementioned drive device 520', control device 620', or drive motor during maintenance, and allows the corresponding high-level radioactive electric valve 500', high-level manual valve 600', or high-level radioactive pump 700' to be completely removed and replaced, thereby improving the maintenance convenience of the valve and pump bodies provided with high radioactive levels.

[0084] It is understood that at least some of the HLA electric valves 500', HLA manual valves 600', or HLA pumps 700' in the emergency discharge system 200', fuel solution transfer and temporary storage system 300', and gas recombination system 400' that are not suitable for underground installation can be entirely located in the first equipment room 1014.

The aforementioned catalyst unit shielding sealing flange may be arranged in the aforementioned maintenance room 1021, and the aforementioned recombiner body may be arranged in the aforementioned first equipment room 1014. Therefore, during maintenance, it is convenient to connect the sling to the aforementioned catalyst unit shielding sealing flange, and to remove and replace the hydrogen-oxygen recombiner 410' as a whole, which is conducive to improving the maintenance convenience of the hydrogen-oxygen recombiner 410'.

[0086] It is understandable that the aforementioned lifting device can be equipped with a shielded maintenance container, which is suitable for grabbing and accommodating the high-level radioactive electric valve 500', high-level radioactive manual valve 600', high-level radioactive pump 700' or hydrogen-oxygen recombiner 410' to be repaired and replaced, thereby facilitating the prevention of radioactive dose leakage of the corresponding equipment during the maintenance of the equipment in the maintenance room 1021.

Based on the aforementioned arrangement, the plant structure 100 for the solution-type medical isotope reactor may utilize discharge components to accommodate part of the piping equipment of the aforementioned emergency discharge system 200', thereby improving the regularity and independence of the piping arrangement of the emergency discharge system 200', improving the operational reliability and safety of the emergency discharge system 200', and facilitating the docking of the emergency discharge system 200' with the reactor vessel 100' and the fuel temporary storage system.

[0089] For example, the discharge room 1015 can be used to accommodate the emergency discharge valve 230' and part of the emergency discharge pipe 220'. The reactor pool 1011 can also be used to accommodate the emergency discharge tank 210' to improve the cooling effect and neutron shielding effect of the emergency discharge tank 210'. The emergency discharge tank 210' can be installed on the inner bottom wall of the main building 110.

Accordingly, the nitrogen purge system can be arranged along the first direction on one side of the primary cooling water system and the secondary cooling water system. In actual use, the pipes used by the nitrogen purge system to connect to the high-radioactivity system can be equipped with a check valve to facilitate isolation from the high-radioactivity system. The check valve can be arranged at the gas consumption point of the high-radioactivity system, and a stop valve can be installed upstream of the check valve. The stop valve can be arranged in the second equipment room 1022 to facilitate maintenance of the stop valve by operation and maintenance personnel.

In actual use, the acid replenishment and water supply main pipe of the acid replenishment system can be connected to the liquid return pipe of the reactor vessel 100' through the aforementioned first equipment room and the reactor pool 1011. A check valve can be installed on the acid replenishment and water supply main pipe, and a stop valve can be installed upstream of the check valve. The stop valve can be arranged in the aforementioned third equipment room 1023 to facilitate maintenance of the stop valve by operation and maintenance personnel. Correspondingly, the pool water purification and cooling system can be arranged along the first direction to one side of the acid replenishment system. In actual use, the pipes of the pool water purification and cooling system can enter and exit the reactor pool 1011 and the temporary storage tank pool 1012 through a shielded casing.

[0096] In some feasible examples, high-energy pipes and some fuel solution storage pipes in solution-type medical isotope stacks can be made of double-walled pipes. The aforementioned double-walled pipes include an outer tube and an inner tube. The outer tube is arranged on the inner tube, and an annular cavity is formed between the outer tube and the inner tube. The aforementioned annular cavity is used to fill with nitrogen with a pressure higher than the medium pressure of the inner tube. In actual applications, the pressure in the aforementioned annular cavity can be monitored to avoid leakage of radioactive gas in the aforementioned high-energy pipes and some fuel solution storage pipes.
