[0053] Figure 1 Schematic diagram of a heat pipe cooling reactor equipment identification method provided in an embodiment of the present application. Figure 1 As shown, the heat pipe cooling reactor equipment identification method includes the following contents:

[0054] Step 101: Determine a list of devices to be analyzed.

[0055] In actual operation, the main systems of the heat pipe cooling reactor can be sorted out to form a list of equipment to be analyzed. The list of equipment to be analyzed mainly includes the system name and its main subsystems or equipment, which serve as input for subsequent equipment identification, narrow the scope of subsequent equipment identification, and reduce the amount of calculation. It should be understood that in some other embodiments, step 101 may not be performed.

[0056] Step 102: Obtain a first equipment list that affects the safety of a heat pipe cooled reactor.

[0057] In some embodiments, a first equipment list affecting the safety of a heat pipe cooled reactor can be obtained based on equipment classification, design phase reliability assurance program (D-RAP) and probabilistic safety assessment (PSA) importance analysis. Equipment affecting the safety of a heat pipe cooled reactor can be identified by integrating equipment classification, design phase reliability assurance program and probabilistic safety assessment importance analysis, and the identification result is more accurate.

[0058] Please refer to Figure 2 , the method for obtaining the first equipment list affecting the safety of a heat pipe cooled reactor includes:

[0059] Step 121: Obtain a list of first sub-devices whose security classification is security level.

[0060] In heat pipe cooled reactors, equipment is usually classified into safety classification, shock resistance classification and other equipment classifications. Safety classification is divided according to the safety functions performed by the equipment (such as controlling reactivity, removing core heat, preventing radioactive release, etc.), and structures, systems and components (SSC) are divided into safety level and non-safety level. Among them, safety level refers to equipment that provides safety functions, and non-safety level refers to equipment that does not provide safety functions.

[0061] The security classification list of the device can be stored locally or in other storage units, and can be obtained from the local or other storage units when needed.

[0062] Step 122: Obtain a list of second sub-devices with a shock resistance classification of shock resistance class I.

[0063] In some embodiments, the impact resistance classification can be carried out according to the performance requirements under the impact reference load, and the SSC can be divided into impact-resistant Class I, impact-resistant Class II and non-impact-resistant classes. Impact-resistant Class I applies to safety-level SSCs, including their supporting items, and refers to SSCs that can withstand the impact of impact loads to ensure their structural integrity and the effectiveness of their design functions. Impact-resistant Class II refers to SSCs that are not required to provide safety functions, but the failure or interaction of their structures may hinder the performance of safety functions. Other SSCs are non-impact-resistant.

[0064] The impact resistance classification list of the equipment can be stored in a local or other storage unit and retrieved from the local or other storage unit when needed.

[0065] Step 123: Obtain the equipment list of the reliability assurance outline in the design phase.

[0066] In some embodiments, based on the probabilistic safety assessment risk analysis, devices whose risk increase value (RAW) is greater than or equal to a first threshold, or whose risk reduction value (RRW) is greater than or equal to a second threshold, or whose cut set importance (FV value) is greater than or equal to a third threshold can be screened out to obtain a list of equipment for the reliability assurance outline in the design phase.

[0067] The risk increase value (RAW) refers to the ratio of the nuclear power plant risk (expressed by the core damage frequency (CDF) or the large radioactive release frequency (LRF)) obtained by setting the reliability value of the equipment to 0.0 to the nuclear power plant baseline risk. For example, the calculation formula of RAW is:

[0068] RAW i =CDF i (p i =1) / CDF0

[0069] in,

[0070] RAW i : The risk increase value corresponding to basic event i;

[0071] CDF0: benchmark CDF;

[0072] CDF i (p i =1): CDF value when the probability of basic event i is 1.

[0073] The risk reduction value (RRW) refers to the ratio of the baseline risk of a nuclear power plant to the risk of a nuclear power plant with the reliability value of the equipment set to 1.0. For example, the calculation formula for RRW is:

[0074] RRW i =CDF0 / CDF i (p i =0)

[0075] in,

[0076] RRW i : Risk reduction value corresponding to basic event i;

[0077] CDF0: benchmark CDF;

[0078] CDF i (p i =0): CDF value when the probability of occurrence of basic event i is 0.

[0079] The FV value (FVW) measures the contribution of an event to the overall risk of a nuclear power plant.

[0080] For example, devices with RAW ≥ 2, RRW ≥ 1.005 (i.e., the RRW of a device exceeds 0.5% of the CDF), or FVW ≥ 0.005 are included in D-RAP, that is, devices with RAW ≥ 2, RRW ≥ 1.005, or FVW ≥ 0.005 are regarded as D-RAP devices to obtain a D-RAP device list.

[0081] It should be noted that the D-RAP equipment list can be stored offline in a local or other storage unit, or can be calculated online.

[0082] In some other embodiments, D-RAP devices can be identified by expert scoring. The experts score all the design phase reliability assurance outline screening questions in turn, and after obtaining the score values ​​of these design phase reliability assurance outline screening questions, the design phase reliability assurance outline devices are screened out based on the score values ​​to obtain a design phase reliability assurance outline device list.

[0083] For example, the D-RAP screening questions are shown in Table 1. For each question, a score is given between 0 and 5 according to the importance and frequency of the question, with a score of 0 for no impact or no occurrence, and a score of 5 for important impact and high frequency. All D-RAP screening questions are scored in turn, and the score value is multiplied by the weight value as the score value of a single question, and the score values ​​of all questions are added up as the total score value. If the score value of a single question is greater than 15 or the total score value is greater than 40, it can be considered that this SSC belongs to a D-RAP device.

[0084] Table 1

[0085]

[0086] Step 124: Based on the probabilistic safety evaluation importance analysis, select the devices with risk increase values ​​greater than or equal to the top M in the fourth threshold or risk reduction values ​​greater than or equal to the fifth threshold to obtain a third sub-device list.

[0087] For example, combined with the importance analysis results of the heat pipe cooled reactor PSA model, the top M (such as 30 or 40 or 50, etc., which can be set according to requirements) component failure and common cause failure basic events are screened out from the basic events of RAW≥100, and the component failure and common cause failure basic events of RRW≥1.1 are screened out at the same time. Then, the top M component failure and common cause failure basic events among the basic events of RAW≥100, or the third sub-equipment list corresponding to the component failure and common cause failure basic events of RRW≥1.1 can be obtained.

[0088] Step 125: Take the equipment included in the first sub-equipment list, the second sub-equipment list, the design phase reliability assurance outline equipment list and the third sub-equipment list as the first equipment to obtain the first equipment list.

[0089] Step 103: Obtain a second equipment list that affects the reliability of the heat pipe cooling reactor.

[0090] In some embodiments, a second list of equipment that affects the reliability of the heat pipe cooled reactor can be obtained based on power generation reliability grading and mission reliability analysis. Equipment that affects the reliability of the heat pipe cooled reactor can be identified from the two aspects of power generation reliability grading and mission reliability analysis, and the identification result is more specific and scientific.

[0091] In actual operation, the fourth sub-equipment list that affects the power generation of the heat pipe cooled reactor can be obtained first, and the fifth sub-equipment list can be obtained based on the mission reliability analysis. Then, the equipment included in both the fourth sub-equipment list and the fifth sub-equipment list can be used as the second equipment that affects the reliability of the heat pipe cooled reactor to obtain the second equipment list.

[0092] For example, the power generation reliability classification is used to identify the equipment that affects the reliability of heat pipe cooled reactors from the perspective of qualitative analysis. Referring to the classification principle of heat pipe cooled reactors, and taking into account the simple structure of heat pipe cooled reactors, the power generation reliability classification is divided into two levels, R and NR, based on the degree of impact on its power generation time and extended shutdown maintenance time:

[0093] R - Failure resulting from equipment outage causing the heat pipe cooling reactor to immediately stop generating electricity or extend the reactor outage for maintenance;

[0094] NR – Failure that would not threaten power generation in a heat pipe cooled reactor.

[0095] Among them, the equipment with power generation reliability graded as R is the equipment that affects the power generation of the heat pipe cooled reactor, thus obtaining the fourth sub-equipment list that affects the power generation of the heat pipe cooled reactor.

[0096] Mission reliability refers to the probability of successfully performing a specified mission within the design life. The equipment that affects the reliability of heat pipe cooled reactors can be identified by converting the mission reliability index into failure rate and then analyzing it using a combination of fault tree and reliability block diagram (RBD).

[0097] Please refer to Figure 3 , the method for obtaining the fifth sub-equipment list based on task reliability analysis includes:

[0098] Step 131: System screening.

[0099] The systems to be analyzed are screened out based on task reliability. Through the system task reliability allocation, the total task reliability of the heat pipe cooled reactor is allocated to each system. Based on the task reliability index of each system determined in the total task reliability allocation, the system level is screened, and the systems that affect the total task reliability of the heat pipe cooled reactor are identified as analysis objects, and the systems to be analyzed are screened out.

[0100] Step 132: Construct a system reliability block diagram.

[0101] Based on the system to be analyzed and the system function, a system reliability block diagram is constructed. From the perspective of system function, a system reliability block diagram is constructed to facilitate subsequent modeling and equipment identification. For example, a reliability block diagram based on task reliability is a simple series-parallel logic diagram.

[0102] Step 133: Determine the sixth sub-equipment list and corresponding failure modes.

[0103] A sixth sub-device list and corresponding failure modes determined based on the system to be analyzed and determined that failure thereof will cause the system to be unable to perform its functions.

[0104] Step 134: Obtain reliability data.

[0105] Reliability data of the devices in the sixth sub-device list are obtained, where the reliability data includes failure rate data corresponding to each failure mode and a corresponding mean time to repair (MTTR).

[0106] Step 135: Establish a system mission reliability model.

[0107] A system task reliability model is established based on the system reliability block diagram and reliability data. In some embodiments, a system task reliability model can be established by means of a fault tree modeling. For the system to be analyzed obtained in step 131, a fault tree modeling is performed using the PSA analysis software. It should be noted that during the modeling process, attention should be paid to collecting relevant information that may cause the system to be unavailable, such as time, technical specification (TS) requirements, failure rate / mean time between failures (MTBF), MTTR, etc.

[0108] Step 136: Quantitative calculation is performed to obtain the fifth sub-equipment list.

[0109] Based on the system task reliability model, quantitative calculation is performed to obtain the top N (such as 20 or 30 or 40, etc., which can be set according to needs) basic events of component failure and common cause failure in terms of cut set importance, and then the fifth sub-equipment list is obtained.

[0110] After the system task reliability model is established in step 135, quantitative calculations can be performed. The equipment that has a greater impact on the heat pipe cooled reactor can be identified by sorting the importance of the cut set. For example, the top 30 basic events of component failure and common cause failure with the FV value are selected. Some basic events are shown in Table 2, and then the fifth sub-equipment list can be obtained.

[0111] Table 2

[0112]

[0113]

[0114] This embodiment combines qualitative analysis and quantitative calculation to identify equipment that affects the reliability of a heat pipe cooled reactor based on power generation reliability classification and mission reliability analysis, respectively, and the identification result is more accurate.

[0115] Step 104: Use the devices included in the first device list or the second device list as target devices to obtain a target device list.

[0116] This embodiment determines the target equipment list that affects the safe operation of the heat pipe cooled reactor from the two aspects of affecting the safety and reliability of the heat pipe cooled reactor, which can comprehensively and effectively identify the equipment that affects the safe operation of the heat pipe cooled reactor and provide important input for subsequent reliability research and demonstration.

[0117] In some embodiments, equipment that affects the safe operation of the heat pipe cooled reactor and that is judged by experts to require special attention may also be obtained and added to the target equipment list to make the equipment list more comprehensive.
