Description

Technical Field

[0001] The invention relates to a method for determining the position of an instrument layout, and more specifically to a method, a device and electronic equipment for determining the position of an instrument layout for a containment leakage rate test. Background Art

[0002] In the containment leakage rate test of a nuclear power plant, it is necessary to deploy a containment leakage rate test instrument consisting of nearly 100 temperature, humidity and pressure sensors inside the containment to collect the environmental data required to calculate the leakage rate. These sensors are usually installed temporarily and are only deployed during regular testing during the shutdown and refueling of the nuclear power plant. They are then dismantled after the test is completed. During the loading operation, there are differences in the radioactivity level inside the reactor, especially during the shutdown and refueling. The installation of sensors faces a certain risk of radioactivity dose. The radioactivity dose borne by personnel is closely related to the radioactivity intensity and residence time in the area.

[0003] According to construction requirements, the radiation dose of installers is strictly limited, including single dose and cumulative dose. During the installation process, if the single dose limit is approached, the personnel need to stop construction and temporarily leave the radioactive area; if the cumulative dose limit is approached, the construction personnel need to be replaced. If the radiation intensity in the area is high or the installation time is long, the installation efficiency and personnel health will be affected, resulting in multiple entries and exits.

[0004] The installation location of the instrument has a direct impact on the radioactivity intensity of the area and the convenience of installation. The containment leakage rate test instrument is usually measured in a space of more than 1,000 cubic meters, so the measurement point layout should give priority to locations with lower radioactivity intensity and have a certain degree of flexibility to ensure the validity of the data. In addition, there are many devices in the measurement point rooms of the containment, and the installation height, channel width and operating space of the instrument will affect the efficiency of installation and disassembly. Therefore, a reasonable design of the installation location can not only save time, but also reduce the radioactivity dose of the installer.

[0005] However, there are significant problems with the current layout of containment leakage rate test instruments. First, the minimum radioactivity intensity of the installation area is not fully considered, resulting in the installers being exposed to a larger radioactivity dose in the same period of time. Second, the convenience of installation is not taken into account, resulting in the installation time being unnecessarily extended in the same radioactivity intensity area. These two problems together result in the installers having to enter and exit the installation point multiple times in different time periods, further extending the installation time and affecting overall efficiency and safety.

[0006] Therefore, it is necessary to design a new method to optimize the layout design of instruments in the radioactive area of ​​the containment to solve the high radioactivity intensity and long installation time caused by unreasonable paths and operating space, thereby improving installation efficiency and reducing radioactive hazards to personnel.

[0066] Figure 1 1 is a flow chart of a method for determining the location of containment leakage rate test instruments provided by an embodiment of the present invention. Figure 1 As shown, the method includes the following steps S110 to S200.

[0067] S110 . Select all arrangable positions in the measurement space according to preselected rules to obtain all candidate installation positions.

[0068] In this embodiment, the candidate installation positions refer to all possible positions where the test instrument can be placed, which are selected according to preset standards and rules in a specific measurement space, that is, a preset space where the instrument needs to be installed. These positions are preliminarily evaluated and meet basic technical and safety requirements, becoming the basis for subsequent optimization and decision-making. By analyzing these candidate positions, the most suitable installation point can be selected to improve the safety and efficiency of the operation.

[0069] The preselection rules include selecting an area with a set radius centered on the measurement space and the operating position space of the surrounding equipment being not less than the set value, selecting a point with the shortest distance from the ground, requiring each different radioactive area to have a preselected point, selecting an area with low radioactive intensity within the radius, and setting at least one of the minimum distances between the preselected point and a solid object.

[0070] Specifically, in the measurement space, a central reference measuring point is first determined, and a radius a*(V) is calculated according to the size of the measurement space volume V. 1 / 3*3 / 4π range, where 0.3>a≥0.2. Select a pre-selected point that meets the conditions from the attachment surface involved in this range; the attachment surface includes the ground, wall, etc. The measurement space here refers to the space where the test instrument needs to be installed.

[0071] Eligible conditions include:

[0072] The pre-selected points cannot affect the installation requirements of other equipment in the space;

[0073] In the same radiation intensity area, adjacent pre-selected points are separated by a radius of 1 meter, both horizontally and vertically. Points at the boundaries of different radiation intensities do not need to consider the radius principle and can be re-preselected in a new area within 1 meter.

[0074] In addition, the above-mentioned central reference measuring point can be determined in the following manner:

[0075] The most direct method is to select the geometric center of the measurement space as the reference point. This usually means picking the midpoint of the three dimensions of the space. This method is suitable for spaces with regular shapes, such as rectangular or cubic spaces.

[0076] If there are particularly important equipment or functional areas in the space, you can consider using locations near these areas as central reference measurement points. This is to ensure that the test data can better reflect the conditions of these key areas.

[0077] When there are multiple functional areas or equipment in the space, a location can be selected so that the distance from this location to each functional area or equipment is relatively balanced. This approach helps ensure that the test results can comprehensively reflect the characteristics of the entire space.

[0078] When selecting the center reference measuring point, try to avoid objects that may interfere with the measurement, such as large equipment, pipelines or other structures. This is to reduce the impact of external factors on the measurement results and improve the reliability of the data.

[0079] Finally, considering the convenience and safety of actual operations, the central reference point should be selected at a location that is easy to reach and does not pose a safety hazard to workers.

[0080] By selecting areas with low radioactivity and appropriate heights, the interference of environmental factors on the measurement results can be significantly reduced, thereby improving the reliability of the data. When selecting pre-selected points, considering the influence of surrounding solids can effectively reduce potential safety risks and ensure the safety of operators and equipment. Selecting pre-selected points through clear rules can avoid waste of resources in the measurement space, ensure reasonable equipment layout, and sufficient operating space. The regularized pre-selected point selection process provides systematicness, facilitates subsequent monitoring and data comparison, and ensures the repeatability of measurements at different times or conditions. These rules and benefits jointly promote the rationality of equipment layout and the effectiveness of measurements in the measurement space, ensuring the successful implementation of experiments or operations.

[0081] S120: For each of the candidate installation locations, generate all feasible paths from the boundary of the non-radioactive area to the candidate installation location.

[0082] In this embodiment, the non-radioactive area is an area where the radioactivity level is low or safe during measurement or installation.

[0083] When determining candidate installation locations, it is necessary to consider the functional requirements of the equipment and the requirements for the environment, such as temperature, humidity, and other factors.

[0084] Starting from the boundary of the non-radioactive area, identify all possible paths to each candidate installation location. This can be achieved through algorithms (such as Dijkstra's algorithm or A* algorithm) to find the shortest path or the optimal path. Evaluate each path, considering obstacles, space constraints, environmental conditions, etc. Ensure that each path is physically feasible and safely accessible. Record all feasible paths and analyze them to ensure that all paths meet safety standards and can effectively support the normal operation of the equipment.

[0085] By identifying and planning paths from non-radioactive areas to candidate locations, the risk of exposure to radioactive environments can be minimized and the safety of workers can be protected. By understanding all feasible paths, the layout of equipment can be optimized, operational efficiency and space utilization can be improved, and the equipment can be installed and used smoothly. Recording multiple feasible paths provides flexibility for future adjustments and maintenance. In the event of equipment failure or routine maintenance, alternative paths can be quickly found to ensure uninterrupted operations. Ensuring that the equipment is installed in the most appropriate location and that the path to the non-radioactive area is clear can reduce measurement errors caused by radioactive effects, thereby improving data reliability. In the event of an unexpected situation (such as a radioactive leak or equipment failure), pre-planned paths can provide guidance for rapid evacuation and emergency response, enhancing overall safety.

[0086] By generating all feasible paths from the boundary of the non-radioactive area to the candidate installation location, the measurement and installation process can be effectively optimized, and work efficiency and data quality can be improved while ensuring safety.

[0087] S130: Eliminate the feasible paths that meet the optimization conditions from all feasible paths corresponding to each candidate installation position to obtain all optimized feasible paths corresponding to each candidate installation position.

[0088] In this embodiment, for all feasible paths corresponding to each of the candidate installation locations, the installation positions of the equipment deployed in the sections and sub-sections in the feasible paths whose widths are less than a preset width threshold are adjusted to obtain the widths of the adjusted sections or sub-sections, and the feasible paths corresponding to the adjusted sections or sub-sections whose widths are less than the preset width threshold are eliminated to obtain all optimized feasible paths corresponding to each of the candidate installation locations.

[0089] In this embodiment, the installation position of the equipment involved on the road section is adjusted according to the needs, specifically according to the installation requirements of the equipment involved. For example, a cabinet needs to maintain a distance of at least 1 meter from other surrounding equipment, and sufficient space needs to be reserved for opening doors and other basic operations. In order to analyze whether there is a possibility of movement or compression of the existing positions of other equipment on the path, a systematic approach can be used to find the optimal solution to ensure that a wider installation path and a larger operating space are provided for the current equipment as much as possible while meeting the minimum space requirements for all equipment layouts. The optimization measures in this process must follow the premise of not interfering with the normal installation and use of other equipment on the path.

[0090] The systematic approach includes path width optimization and installation space optimization; specifically, path width optimization: for all sections on the feasible path that fail to achieve the maximum travel speed due to insufficient width, we first evaluate whether the current positions of these devices allow them to be moved or compressed in the direction of widening the path based on the installation requirements of the surrounding equipment that hinders the path width. By calculating the minimum installation space requirements for each device and the necessary spacing between it and the surrounding equipment, we can determine the maximum movable range of each device. On this basis, mathematical models such as linear programming or genetic algorithms are used to solve the optimal solution, that is, to maximize the path width without violating any installation requirements, thereby improving travel efficiency.

[0091] Installation space optimization method: For all locations where installation time is extended due to limited installation space, it is also necessary to examine whether the existing installation locations of these devices support their movement or compression in the direction of increasing installation space based on the installation requirements of the surrounding devices that hinder the installation space. In this process, we regard each device as a variable and its installation space requirement as a constraint, and find the best configuration solution by building a multi-objective optimization model. The model aims to simultaneously meet the minimum installation space requirements of all devices and shorten the overall installation time as much as possible.

[0092] The feasible paths corresponding to the sections or sub-sections whose widths after adjustment still do not meet the preset width threshold are eliminated. The width of the path is optimized to ensure smooth passage of equipment, personnel or vehicles to avoid congestion and interference. This includes evaluating and adjusting all sections on the path that are less than the maximum width.

[0093] The maximum width refers to the minimum width that can achieve the maximum travel speed, which is usually related to factors such as travel time and traffic flow.

[0094] The route is divided into multiple sections according to the intensity of the radiation in the area it passes through, and the sections are further divided into multiple sub-sections according to the width of the route, so that each section can be analyzed and optimized. The width and space requirements of each section may be different, so personalized adjustments are required.

[0095] During the optimization process, the space and distance requirements of surrounding equipment need to be considered. Each device has its minimum safe distance and space requirements when operating, which must be met during the optimization process.

[0096] Adjust the placement of equipment along the path based on the assessment of the path width. Increase the width of the path by repositioning equipment to ensure that the path can reach or be as close to the maximum width as possible.

[0097] After optimization, the travel time of the path needs to be evaluated to ensure that the equipment's operating efficiency is improved and to avoid delays caused by insufficient width.

[0098] By optimizing the path width, obstacles to traffic can be reduced, and the efficiency of equipment and personnel movement can be improved, thereby shortening working hours. Wide paths can effectively avoid congestion and reduce delays and safety hazards caused by the gathering of people or equipment. When adjusting the position of equipment, ensuring sufficient safe space can reduce the risk of accidents and ensure the safety of workers. By properly arranging equipment, space can be used more effectively, unnecessary occupation and waste can be avoided, and the utilization rate of the overall working environment can be improved. After the equipment layout is optimized, the entire work area will be more flexible and can be adjusted and changed more easily to cope with future changes in demand.

[0099] S140, calculating the path radioactive doses of all the feasible paths after optimization corresponding to each of the candidate installation positions, so as to obtain the radioactive dose of each of the feasible paths corresponding to each of the candidate installation positions.

[0100] In this embodiment, the radioactive dose of each feasible path corresponding to each candidate installation location refers to the total amount of radioactive radiation that a person may be exposed to when traveling on the path. This dose is calculated by combining the radioactive intensity of each section on the path with the travel time.

[0101] In one embodiment, see Figure 2 , the above-mentioned step S140 may include steps S141 to S145.

[0102] S141. For all the optimized feasible paths corresponding to each of the candidate installation positions, divide the road sections according to the radioactivity intensity of the areas passed by the feasible paths to obtain a plurality of road sections, and determine the radioactivity intensity corresponding to the road sections.

[0103] In this embodiment, all feasible paths after optimization at each candidate installation location are segmented according to the radioactivity intensity of different areas, ensuring that safety is fully considered when planning the path and reducing the risk of personnel being exposed to high radioactivity areas.

[0104] like Figure 4 As shown in the figure, when the path passes through multiple areas with different radioactivity intensities, the calculation is first performed by segmentation according to the radioactivity intensity, and each segment is divided into R 11 , R 12 , R 13 , ..., R 1n (The corresponding path lengths are L1, L2, L3, ..., L n ), where the radioactivity intensity of each section is R1, R2, R3, ..., R n .

[0105] S142: Divide each of the road sections into a plurality of sub-sections according to the path width, and determine the length of each of the sub-sections.

[0106] S143. Determine the personnel travel speed of each of the sub-sections according to a set relationship between the personnel travel speed and the path width.

[0107] In this embodiment, the relationship between the set personnel travel speed and the path width is determined through a number of historical data.

[0108] For each road segment R nm Further division is performed to form multiple sub-segments R nm1 , R nm2 , R nm3 , …, Rnmx , and determine the corresponding sub-segment length L n1 , L n2 , L n3 , …, L nm and the travel speed V n1 , V n2 , V n3 , …, V nm .

[0109] There is a certain relationship between the personnel travel speed v and the path width, such as Figure 5 As shown in Figure 1, the wider the path, the faster the travel speed. When the path width reaches a certain value, the speed of the personnel will reach the maximum value.

[0110] S144. Calculate the travel time of each sub-section according to the length of each sub-section and the speed of people traveling on each sub-section, and sum the travel time of all sub-sections corresponding to each section to obtain the travel time required for each section.

[0111] In this embodiment, the time required for a person to pass each road section is calculated:

[0112] The travel time of each sub-segment is T nm =L nm / V nm ; The total travel time for each section is T n =∑T nm ∣m.

[0113] S145. Multiply the travel time required for each of the road sections by the radioactivity intensity corresponding to the road section to obtain the product of each of the road sections, sum the products of all the road sections and multiply by two to obtain the radioactivity dose of each of the feasible paths corresponding to each of the candidate installation locations.

[0114] In this embodiment, according to the design of the round-trip path, the radiation dose of the path is calculated as: F = (R1·T1+R2·T2+…+R n ·T n )×2.

[0115] By accurately calculating the radioactive dose of different paths, the safety of each path can be effectively evaluated, helping to select a route that minimizes radiation exposure. The route of personnel can be optimized according to the radioactive intensity and travel time of the path, thereby improving work efficiency. Under different environmental conditions (such as changes in radioactive intensity and path width), the travel speed and radioactive dose can be quickly recalculated to ensure the flexibility and adaptability of path planning. Providing scientific data support for decision makers enables them to make more reasonable choices when facing potential radioactive risks.

[0116] S150. Select a feasible path with the minimum radioactive dose according to the radioactive dose of each feasible path corresponding to each candidate installation position, so as to obtain a candidate path corresponding to each candidate installation position.

[0117] In this embodiment, the candidate path corresponding to each candidate installation position refers to a feasible path with the minimum radioactive dose corresponding to each candidate installation position.

[0118] Selecting the path with the lowest radioactive dose can effectively reduce radiation exposure of workers and surrounding personnel and reduce health risks. Through scientific calculation and selection, the safety of traveling in a radioactive environment can be ensured, providing more reliable protection for personnel operations. Selecting the best path among many candidate paths can optimize the use of resources, improve work efficiency, and reduce unnecessary time and costs. Based on quantitative data and analysis results, it provides scientific basis for management and makes the decision-making process more transparent and reasonable. When the path needs to be adjusted quickly, the radioactive dose of different paths can be quickly evaluated, thereby improving the flexibility and effectiveness of emergency response. Ensure that the selected path meets relevant radioactive safety standards and reduce compliance risks.

[0119] S160: Optimize the layout positions of the devices around each candidate installation location to obtain an optimized candidate installation location.

[0120] In this embodiment, under the condition that the space and distance required by the peripheral devices are met, the installation position of the peripheral devices of each candidate installation position is adjusted to obtain each of the candidate installation positions after optimization.

[0121] In this embodiment, peripheral devices refer to other cabinets, boxes, panels, instruments, cables and other devices deployed around the candidate installation location. First, peripheral devices refer to those devices that are physically close to the candidate installation location. The "closeness" here can be defined according to the specific application scenario. For example, in some cases, it may refer to all devices that are no more than a certain distance (such as 1 meter) from the candidate installation location; in other scenarios, it may refer to all devices in the same room, the same floor or the same area. In addition to physical proximity, peripheral devices also include those devices that have functional interactions or dependencies with the devices at the candidate installation location. Even if these devices are relatively far apart in physical location, if there is interaction such as data exchange, signal transmission, mechanical connection, etc. between them, they should also be regarded as peripheral devices. Considering the impact of the device on the surrounding environment is also an important factor in defining peripheral devices. For example, devices that generate a lot of heat or electromagnetic interference may affect nearby sensitive devices even if they are physically far away, so such devices should also be included in the category of peripheral devices. Finally, relevant industry standards and safety specifications must be complied with, which usually clearly specify the minimum safe distance between devices. Therefore, any device that may affect the safety distance should be regarded as a peripheral device.

[0122] Expanding the operating space can make it easier for workers to operate and reduce inconvenience and restrictions at work. Larger space helps reduce interference between equipment, making the operation process smoother, thereby improving overall work efficiency. Reasonable equipment layout can maximize the use of available space, avoid space waste, and improve resource utilization. Increasing the operating space on the basis of ensuring a safe distance can help reduce accidental risks and improve the overall safety level. Larger operating space facilitates equipment maintenance and overhaul, reduces operational difficulty, and improves work efficiency.

[0123] Specifically, the adjustment of the positions of the surrounding devices may refer to the adjustment of the devices involved in the road section or sub-road section, which will not be described in detail here.

[0124] S170, calculating the operational radioactive dose for each of the optimized candidate installation positions to obtain the operational radioactive dose corresponding to each of the candidate installation positions.

[0125] In one embodiment, see Figure 3 , the above-mentioned step S170 may include steps S171 to S173.

[0126] S171. Determine an operation complexity coefficient and an operation time according to the optimized operation space around each candidate installation position.

[0127] In this embodiment, the operation complexity coefficient is used to indicate the complexity of the operation.

[0128] Specifically, the installation and disassembly time of the instrument and the spatial relationship with surrounding equipment. For example, Figure 6 As shown, the space around the instrument is inversely proportional to the time required for installation / disassembly. Specifically, the larger the space, the shorter the operation time until a certain space threshold is reached, at which point the time reaches the minimum value. This means that sufficient space should be given priority to the instrument during design and layout to improve operation efficiency.

[0129] The operation complexity is divided into three cases:

[0130] Within the directly manually operable height range: The operation is simple and easy to complete manually, and the set complexity coefficient is o.

[0131] Beyond a certain height / depth: Equipment such as stairs and extension tools are required, and the complexity coefficient is set to p.

[0132] Beyond a relatively large height / depth: Large equipment is required, and the operation difficulty increases significantly, and the complexity coefficient is set to q.

[0133] Among them, the complexity coefficients follow the relationship o < p < q, which can be defined according to the actual situation. This classification helps to evaluate the difficulty of different operations and provides a basis for subsequent time and dose calculations.

[0134] S172. Determine the radioactive intensity of each of the optimized candidate installation positions.

[0135] In this embodiment, the radioactive intensity of each optimized candidate installation position can be measured by a sensor or the like.

[0136] S173. Multiply the radioactive intensity, operation complexity coefficient, and operation time of each of the optimized candidate installation positions to obtain the operation radioactive dose corresponding to each of the candidate installation positions.

[0137] In this embodiment, during the installation or disassembly process, the calculation formula for the radioactive dose is:

[0138] F2 = R′ × T′ × A; where R′ represents the radioactive intensity of the installation point, T′ represents the installation time, and A is the operation complexity coefficient. This calculation can help evaluate the radioactive dose to which the staff is exposed during the operation, so as to formulate corresponding safety measures.

[0139] By analyzing the operation time and space, the installation and removal time of the instrument can be effectively reduced, and the overall work efficiency can be improved. Complexity analysis helps to identify the difficulty of different operations, so that corresponding operation guidelines can be formulated, complex operations can be simplified, and work safety can be improved. By calculating the radioactive dose, the operation risk can be assessed in advance, so that appropriate protective measures can be taken to ensure the safety of the staff. This analysis provides data support for the layout of the instrument and its surrounding equipment, which helps to make reasonable planning in the design stage, thereby avoiding operational difficulties in the later stage. Reasonable space and operation design can reduce the physical exertion of staff, reduce the workload caused by the complexity of operation, and improve job satisfaction. The calculation and analysis of radioactive dose can ensure that the operation complies with relevant safety regulations, reduce legal risks, and ensure that the company operates in compliance with regulations.

[0140] Systematic analysis of operation time, complexity and radiation dose can provide strong support for improving work efficiency, safety and compliance.

[0141] S180, calculating the total radioactive dose according to the operational radioactive dose corresponding to each candidate installation position and the radioactive dose of the candidate path corresponding to each candidate installation position, so as to obtain the total radioactive dose corresponding to all the optimized candidate installation positions.

[0142] In this embodiment, the total radioactive dose (according to installation + disassembly twice) is: F=2*(F1+F2).

[0143] S190, selecting the optimized candidate installation position with the smallest total radioactive dose from the total radioactive doses corresponding to all the optimized candidate installation positions to obtain the target deployment point and the corresponding position information.

[0144] All optimized candidate installation positions are analyzed and calculated, and the position with the smallest total radioactive dose is selected as the instrument position.

[0145] S200: Output the target deployment point, the corresponding location information and the corresponding candidate path.

[0146] In this embodiment, the target deployment point, location information, and the best path are output together, so that the operator can install the instrument according to the output content.

[0147] The method of this embodiment aims to design and optimize the position of the instrument by analyzing the radioactivity intensity of the instrument layout location, the radioactivity dose of the installation path, and the radioactivity dose of the installation space, so as to find the installation point with the lowest cumulative radioactivity dose while meeting the measurement requirements.

[0148] Specifically, the method of this embodiment evaluates the adjustable space of the equipment on both sides of the road section that affects the travel time on the installation path. By optimizing the layout of the equipment around these sections, the passage width is expanded, thereby reducing the path travel time. In addition, the adjustable space of the equipment around the operation position is analyzed, and the layout is optimized to expand the operation space and reduce the operation time.

[0149] After comprehensively analyzing the total radioactive dose after optimization of each possible layout position, the method of this embodiment will select the layout point with the minimum radioactive dose. This method is not only applicable to all instrument layout designs of nuclear power plants, but can also be extended to other environments with similar design requirements, such as instrument layout under extreme conditions such as high temperature, low temperature or chemical conditions.

[0150] The method of this embodiment provides technical support for improving the efficiency of instrument installation and reducing the radiation dose of installers, thereby solving the problem of high radiation intensity and long installation and disassembly time caused by unreasonable design of paths and operating spaces.

[0151] The method of this embodiment reduces the radioactivity intensity at the installation and removal location of the instrument, reduces the installation and removal time of the instrument, and avoids the problem of high radioactivity hazards to the installers. While meeting the instrument measurement requirements, by optimizing the layout design of the instrument and peripheral equipment, the radioactivity dose borne by the instrument installers and removers during the operation is reduced, the risk of radioactivity hazards is reduced, and the efficiency of instrument installation is improved.

[0152] In addition, this embodiment can also effectively reduce the radioactivity intensity of the entire path and the measuring point position through radiation shielding technology. This process usually includes the following steps:

[0153] Choose the appropriate shielding material based on the type and energy characteristics of the radiation source. Commonly used shielding materials include lead, concrete, steel, and polyethylene. Different materials have different shielding effects on different types of radiation (such as gamma rays, beta rays, or neutron radiation).

[0154] Design a reasonable shielding structure, including shielding walls, shielding doors and other protective devices to ensure that the shielding material can cover the radiation source and the measurement point. The thickness and layout of the shielding structure need to be calculated based on the radiation intensity to ensure the required shielding effect.

[0155] Arrange shielding materials around instrument installation paths and measurement point locations to reduce the possibility of radiation passing through. This includes installing shielding layers on the walls, ceilings and floors of the passage, especially in areas that may be touched during installation and operation.

[0156] In some cases, the placement of shielding materials can be dynamically adjusted based on specific operational needs. For example, when performing maintenance or inspection, shielding can be temporarily added to further reduce radiation intensity.

[0157] After installing the shielding device, continuously monitor the radiation intensity to evaluate the shielding effect. If necessary, adjust the shielding design and materials in time to ensure that the radiation level is always maintained within the safe range.

[0158] The above-mentioned method for determining the layout position of the containment leakage rate test instrument selects all candidate installation positions that can be arranged and generates feasible paths for each position to optimize the layout of instruments in the radioactive area, optimizes these paths to reduce the radiation dose, and calculates the radiation dose of each path. The point with the smallest total radiation dose is screened out from the optimized candidate installation positions, and relevant information is output to optimize the layout design of instruments in the radioactive area of ​​the containment to solve the high radiation intensity and long installation time caused by unreasonable paths and operating spaces, thereby improving installation efficiency and reducing radiation hazards to personnel.
