[0012] The overall arrangement of an exemplary system is described in detail below with reference to Figure 1. Thereafter, specific elements of a steam generator and associated sensors are further detailed below with reference to Figures 2A to 4
[0013] Figure 1 is a partially schematic partial cross-sectional view of a nuclear reactor system 100. The system 100 includes a power module 115, which has a reactor core 101 in which controlled nuclear reactions occur. Accordingly, the reactor core 101 may include one or more fuel assemblies 116. The fuel assemblies 116 may include fissile and / or other suitable materials. Heat generated by the reaction The steam generator 120 generates steam, and the steam generator 120 converts that steam into electricity. It is directed to the power conversion system 170. The power conversion system 170 generates power and / or other Provides a useful output for the power module 115 and / or other system components. A sensor system 150 is used to monitor the operation. The data obtained is used in real time to control the power module 115. It is possible, and / or the power module 115 and / or other system components It can also be used to update the design of the network.
[0014] The power module 115 includes a containment vessel 102, and the containment vessel 102 contains the reactor pressure vessel 106. To contain / enclose. The reactor pressure vessel 106 contains the reactor core 101. The containment vessel 102 contains the power motor. It can be housed in the Joule Bay 103. The power module bay 103 is water and / or other suitable It houses a cooling pool 104 filled with a cooling fluid. Most of the power module 115 It is located below the surface 105 of the cooling pool 104. Therefore, the cooling pool 10 4 can, for example, function as a thermal sink in the event of a system malfunction.
[0015] The volume between the reactor pressure vessel 106 and the containment vessel 102 is such that the volume from the reactor pressure vessel 106 to the surrounding environment It may be partially or completely exhausted to reduce heat transfer (for example, to the cooling pool 104). However, in another embodiment, the space between the furnace pressure vessel 106 and the containment vessel 102 The product is designed to increase heat transfer between the reactor pressure vessel 106 and the containment vessel 102, and includes gas and / Alternatively, the container may be filled at least partially with liquid.
[0016] Inside the reactor pressure vessel 106, the primary coolant 109 absorbs heat from the core 101 into the steam generator 1 Send to 20. For example, as indicated by the arrows placed inside the pressure vessel 106, primary The coolant 109 is heated in the core 101 and moves toward the bottom of the reactor pressure vessel 106. The primary coolant (e.g., water with or without additives) flows from the core 101 to the core shroud 10 It rises through 7 to riser tube 108. The hot, buoyant primary coolant 109 rises - It continues to rise through pipe 108, then exits riser pipe 108 and passes through steam generator 120. It detaches and descends. The steam generator 120 is, for example, spiral, as schematically shown in Figure 1. The pattern includes numerous conduits 122 arranged circumferentially around the riser tube 108. The descending primary coolant 109 transfers heat to the secondary coolant (e.g., water) in the conduit 122. The signal is transmitted and descends to the bottom of the reactor pressure vessel 106, where the cycle restarts. The Kuru can be driven by the change in buoyancy of the primary coolant 109, therefore the primary coolant 1 The need for a pump to move unit 09 can be reduced or eliminated.
[0017] The steam generator 120 includes a feedwater header 121. The incoming secondary coolant is supplied to the feedwater header 12 The secondary coolant enters the steam generator conduit 122 via 1. The secondary coolant passes through the conduit 122. It rises, is converted into steam (e.g., water vapor), and is collected in the steam header 123. The steam exits the steam header 123 and is directed towards the power conversion system 170.
[0018] The power conversion system 170 transmits high-pressure and high-pressure steam from the steam generator 120 to the steam turbine 173. It may include one or more steam valves 172 that regulate the passage of hot steam. Steam turbine 173 The thermal energy of the steam is converted into electricity via the generator 174. From the turbine 173 The low-pressure steam released is condensed in the condenser 175, and then (for example, via the pump 176) The water is directed to one or more water supply valves 171. The water supply valves 171 direct the water supply to the water supply head. The speed at which the steam enters the steam generator 120 again via Da 121 is controlled.
[0019] The power module 115 includes numerous control systems and associated sensors. For example, the power module Joule 115 may include a hollow cylindrical reflector 110. The hollow cylindrical reflector 110 is used to reflect neutrons The control rods 111 are returned to core 101 to promote the nuclear reaction in core 101. Used to adjust the reactor pressure vessel 106, and driven via the fuel rod driver 112. The internal pressure is controlled by the pressurizer plate 113 (which also contains the primary coolant 109 and the steam generator 120) (It can also serve to direct downwards through this) and is positioned above the pressurizer plate 113 This can be controlled by controlling the pressure in the predetermined pressurized volume 114.
[0020] The sensor system 150, for example, changes in operating parameter values and / or parameter values. To identify the location, various locations within and / or elsewhere in the power module 115 are determined. It may include one or more sensors 151. The data collected by the sensor system 150 Subsequently, in order to control the operation of system 100, and / or design changes for system 100 It can be used to bring about further improvements. For sensors positioned inside the containment vessel 102 The sensor link 152 receives data from the sensor (the sensor link 152 connects to the containment container 1 (The part coming out of 02) is directed towards flange 153, and the data is taken from the sensor junction box. It is directed to bus 154. From there, the sensor data is sent via data bus 155 to one or more devices. It is routed to the controller and / or other data systems.
[0021] One challenge associated with nuclear reactors, particularly the steam generators within them, is the conversion of water into steam. The exchange process may not occur uniformly or smoothly within the steam generator. It is located there. In particular, density waves are formed within the conduit of the steam generator, and the conduit of the steam generator Density wave vibrations can be introduced that cause vibration and stress in the and / or other elements. Figure 2A As detailed below with reference to Figure 4, several aspects of this technology are achieved by density wave oscillations. Improved sensors and related technologies for detecting the characteristics of a steam generator, including the strains that occur as a result. Regarding.
[0022] Figure 2A shows a typical configuration having multiple conduits 122 arranged around a central opening 125. This is a partially schematic isometric view of the steam generator 120. The central opening 125 is shown in Figure 1. The riser tube 108 described above is housed in the conduit 122. To provide extensive thermal and fluid contact between the wall and the surrounding primary coolant, the middle is arranged in a helical manner. It may be arranged in one or more conduit bundles 124 that encircle the heart opening 125. Water is supplied to the water supply. From the lid 121, it enters the conduit 122 and exits through the steam header 123. Conduit 1 22 can be supported by a number of conduit supports 130. Individual conduit supports Arranged in a conduit support stack, 130 extends radially outward from the central opening 125. It can be set to 131. Each conduit support 130 is described later with reference to Figure 2C. Upper support rail aperture 132 and lower support rail aligned along the corresponding rail It may include a luapach 133. In the illustrated embodiment, four conduits 122 are shown. However, it should be understood that the above is merely one example of a case where the subject matter of disclosure is not limited. It can be done.
[0023] Figure 2B is a magnified view of a portion of a typical conduit support stack 131. The conduit support 130 and the corresponding conduit 122 are shown. 130 may include a carrier portion 134 and one or more retainer portions 135. For example, in Figure 2B As shown, the retainer portion 135 supports each conduit 122 in place. The conduit 122 may include projections extending below and / or above it. Generally, the conduit 122 is For example, to accommodate dimensional changes due to thermal expansion, it is firmly attached to the retainer portion 135. That is not the case. As shown in Figure 2B, the conduit support stack 131 has a large number of Includes spaced conduit supports 130. The "layers" of conduit 122 are adjacent to conduit It is supported between 130 pairs of support structures.
[0024] Figure 2C shows the upper support positioned to align the corresponding conduit support 130. The main support rail 136 and the lower support rail 137 are shown. For illustrative purposes, two pairs of conduits are shown. The support rail 130 is connected to the corresponding upper support rail 136 and lower support rail 137. They are shown to be aligned to the rail 1. A number of additional conduit supports 130 are then placed on the rail 1. They are aligned radially along R, as shown in Figures 2A and 2B.
[0025] Figure 3 shows a typical conduit support 130 configured according to several embodiments of the present technology. This is a partially schematic cross-sectional view. The conduit support 130 has one carrier portion 134, and multiple It may include a number holder portion 135 and one or more sensors 151. These are all one It is formed integrally as a unit. Therefore, the conduit support 130 is, here It may be referred to as an instrumentation support or instrumentation conduit support. For example, the sensor 151, the retainer portion. 135 and the carrier portion 134 can be integrally formed via additive manufacturing techniques. Appropriate techniques This includes the use of laser powder beds or direct energy-impedance 3D printers. However, However, this technique involves the embedded sensor 151 using such 3D printing technology. The law may be limited to typical high-temperature applications. For sensors that cannot withstand certain temperatures, ultrasonic additive manufacturing (ultrasonic The additive manufacturing (UAM) technique is used instead. For example, UAM techniques can be used to melt structures containing both metallic and non-metallic components. It can be used for additive manufacturing without melting. This allows for the joining of dissimilar metals. This is permitted, and clad materials, metal matrix composites, and / or "smart" materials. This makes it easier to stack reactive structures. As a result, it becomes easier to prevent tampering and / or failure. Sensor electronics are installed in a protective structure that prevents adverse processing (for example, the structure of the conduit support 130). It can be embedded (below the outer surface of the supporting structure). In other words, the sensor is, Also, completely or at least partially encapsulated in a non-destructive manner within the structure being formed. / By being sealed, it is protected from the harsh environment inside the steam generator. In addition, the structure This may include complex internal shapes. These complex internal shapes can be easily fabricated using additive manufacturing techniques. While this is possible, shaping using conventional subtractive techniques becomes difficult and impractical. For example, the conduit support 130 may include an opening 138. This opening 138 supports Reduce the amount of spent material used to form the body, and the water vapor in the conduit. Reduces heat transfer away from the body. Furthermore, as a result of the fidelity of the additive manufacturing process, post-manufacturing processing ( For example, the need for machining can be reduced or eliminated.
[0026] In a typical embodiment shown in Figure 3, the sensor 151 is an optical fiber strain gauge Includes the 156 and related communication link 152. The communication link 152 also includes optical fiber elements. Obtain. In one such embodiment, the strain gauge 156 is integral with the retainer portion 135. The conduit is formed and supported by the retainer portion 135, and the retainer portion 135 This allows for accurate recording of such strain changes. (Conduit shown in Figures 2A to 2C) (The conduit support 130 moves along the corresponding conduit axis 126 from one conduit support 130 to the next It extends to the conduit support. In various embodiments, the strain gauge 156 is a retainer portion Since it is formed integrally with part 135, the material of the retainer part 135 may, for example, radiate from the reactor core. This can help shield the strain gauge from the gamma radiation being emitted. Such radiation is Because it discolors the optical instruments of the strain gauge 156 and / or communication link 152, the sensor Operability can be reduced or eliminated. The optical strain gauge 156 can be embedded, for example, in a metal material. This makes it possible to reduce, delay, and / or eliminate the possibility of such deterioration, The ability to measure strain characteristics in a steam generator can be improved. For example, Figure 3 As shown, the strain gauge 156 is integrated with the retainer portion 135 and the communication link 15 2 is integrated with the carrier portion 134, similar to the retainer portion 135. Conduit support (for example) The material forming the carrier portion 134 and / or retainer portion 135) is, in some embodiments, In some embodiments, stainless steel is included, and in other embodiments, other suitable materials may be included. .
[0027] Figure 4 shows a typical optical fiber strain gauge 156. This is a general conventional structure Although it has a structure, it is integrally formed with the corresponding support using the UAM technique. Such a false label One possible representative device for doing this is Aniwaa (www.aniwaa.com). Includes the SonicLayer® 7200 automation system, available from [company name]. This is an example of what is done, but the subject of disclosure is not limited. The UAM system is A silica core 157 that transmits the light beam 158 can be formed. The silica core 157 protects With the aim of preventing light leakage from the core 157, it is surrounded by cladding 159. The core 157 may contain a number of Bragg grid elements 160. This determines whether the strain gauge 156 is under strain, and if so, what its properties are. The UAM process refracts and / or reflects light in different ways depending on the strain value. Also, the strain gauge 156 and the surrounding conduit support 130 are simultaneously connected to the communication link 152 ( This may also include forming a number of communication links 152, supported by corresponding conduits. It can be routed through the body to the appropriate junction box or other connecting structure. The data collected by the sensor is then processed using the flange 153 described above, as shown in Figure 1. It is routed outside the reactor through a strain gauge 156 and / or other type. At least one material forming the sensor is less than the material forming the conduit support 130 Since they are all different materials, despite such differences, the process is carried out successfully. The additive manufacturing process is selected.
[0028] The data acquired from the sensors is used to improve reactor efficiency and / or to improve the corresponding reactor. It can be used for one or more purposes that result in profit. For example, driving In the middle, the sensor accurately detects strain that can correspond to density wave oscillations and / or other flow phenomena. Therefore, operators can adjust system operation parameters to prevent such phenomena from occurring. The data can be adjusted. In other applications, the data is density wave oscillation and / or to design or redesign furnace elements to reduce the likelihood of other flow phenomena occurring. It can be used for the following: Or, in another typical embodiment, the target vibration frequency value and / or to produce an amplitude value, for example, an acceptable target value for furnace operation, by designing the elements or It's okay to redesign it.
[0029] For illustrative purposes, the typical sensors shown in Figures 3 and 4 are optical strain sensors. In other embodiments, the sensor may have other structures and / or other parameter values. It may be used for measurement. For example, the sensor may be used to measure the steam generation in which the sensor is located. A thermal sensor configured to measure the local temperature inside a container or other system component. (For example, thermocouples may be included.) Data obtained from the thermal sensor may be taken from the strain sensor. Along with the obtained data, the characteristics of density wave oscillations and / or other flow phenomena are further quantified and / or can be used to understand. In other embodiments, a thermal sensor (and / or (Other sensors) can measure various appropriate flow parameters, thermal parameters and / or structural parameters. It can also be used independently to evaluate any of the factors.
[0030] In any of the embodiments described above, the structure on which the sensor is located is simultaneously with the sensor itself. Using the ability to additively fabricate sensors, we can create arrays of multiple sensors (e.g., 3D arrays). It can be produced at a high rate, and this array is more accurate than a set of small, scattered sensors. Furthermore, it is possible to capture phenomena in a multidimensional environment. This capability allows for data accuracy and This allows for further improvement in the effectiveness of the steps taken based on that data. The data collected by the sensors described above is generally static and depending on the application. / or it can be dynamic. For example, density wave oscillations generally occur in the steam generator conduit 122. In the boiling region, it has a frequency of approximately 0.1 Hz to 0.3 Hz. Therefore, strain The sensor measures strain changes at a frequency high enough to capture the aforementioned periodicity. It can be constructed.
[0031] The above data is for the above application (e.g., steam generator reliability for future designs). Improvement of performance, and / or early indication or prediction of steam generator conduit fatigue. In addition to providing, for other purposes, for example, inspection of the furnace's steam generator and / or other elements. To narrow down or concentrate such testing to the areas most likely to require it, This also allows for the elimination of the need for structural inspections that may not otherwise be required. The associated costs can be reduced. In other applications, thermal sensor arrays Alternatively, thermal data obtained from the network can accurately predict the heat transfer characteristics within the steam generator. It can be used to do so. This affects the design of the steam generator, so it is efficient. This allows for the creation of robust and / or inexpensive steam generators.
[0032] From the above, it is clear that specific embodiments of the technology disclosed for illustrative purposes are described herein. Despite this, various modifications can be made without deviating from the technology in question. For example, the sensor may detect parameters other than strain and / or temperature. It is also possible. The sensor may be a non-optical sensor and / or via a non-optical communication link. Data may be communicated. A typical embodiment is positioned on a steam generator conduit support. Despite showing a sensor, other multiple embodiments of the sensor require other systems It may be positioned as is. The sensor positioned on the steam generator is located on the conduit support. It may be incorporated into the holder portion and / or other parts of the conduit support, such as the carrier portion. It may be incorporated into the minutes.

Furthermore, the advantages associated with a particular embodiment of the disclosed technology are Although described in the context of these embodiments, other embodiments may also demonstrate such advantages.
