[0002] The management scope of a nuclear power plant includes assumptions used in safety analyses (e.g., initial reactor power and initial boron concentration), safety functions required for accident mitigation (e.g., reactor scram, emergency boronization, and emergency water supply), and post-accident monitoring functions (e.g., post-accident monitoring instrumentation, such as core cooling monitoring). This involves a large number of instruments, which are essential for achieving nuclear power plant safety functions. Therefore, ensuring the safe operation of a nuclear power plant requires, first and foremost, ensuring the operational safety of these instruments.

[0053] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0054] In one embodiment, Figure 1 As shown, an instrument monitoring method is provided, which is executed by a computer device and specifically includes the following steps:

[0055] S101: Acquire instrument status information and instrument measurement data information of each instrument in a target instrument group, as well as operation mode information corresponding to the target instrument group.

[0056] Each instrument in the target instrument group corresponds to the same measurement task. It is understood that in a nuclear power plant, instrument channels generally include sensors located on-site and signal converters, signal conditioners, logic, and shutdown circuits located in the control room and instrument room instrument cabinets. Generally speaking, instrument channels for critical measurement functions in a nuclear power plant are configured as four redundant channels. Redundant channels are provided to meet the single failure criterion and enhance the availability of the nuclear power plant. The data links of each instrument channel remain independent to prevent fault transmission between channels. Therefore, each instrument in the target instrument group of this embodiment corresponds to the same measurement task, i.e., instruments with multiple redundant channels corresponding to the same critical measurement function.

[0057] Optionally, when determining the target instrument group, it is necessary to consider the impact of key measurement functions (instrument functions) on the safe operation of the unit. Therefore, in this embodiment, only the safety-level instrument data mentioned in the technical specifications is extracted, and non-safety-level instrument data is excluded. For example, the safety-level instruments mentioned in the technical specifications include: reactor emergency shutdown system instruments, dedicated safety facility drive system instruments, post-accident monitoring instruments, emergency diesel generator start-up instruments, main control room air conditioning system trigger instruments, boron dilution protection system instruments, containment ventilation system trigger instruments, fuel plant ventilation system trigger instruments, etc.

[0058] Among them, the instrument status information refers to whether the instrument is a valid instrument or an invalid instrument; the instrument measurement data information refers to the data measured by the instrument; the operation mode information corresponding to the target instrument group refers to the unit operation mode. The unit operation mode is the unit status when there are fuel assemblies in the reactor building, including any combination of the following factors: reactivity status, core thermal power, average reactor coolant temperature, and the bolt tension status of the reactor pressure vessel top cover.

[0059] For example, the operating mode of a nuclear power plant (unit) is defined and determined based on physical parameters such as the core reactivity state, unit thermal power, and average reactor coolant temperature. Table 1 shows a typical classification of nuclear power plant operating modes:

[0060] Table 1- Operation mode judgment

[0061]

[0062] It is understandable that not all instruments are required to be operational in all operating modes, and each instrument function is applicable to different operating modes. If the current operating mode requires these instruments to be operational, the technical specification will define the operating restrictions for the instrument. When one or more instruments are not operational, the event corresponding to the operating restriction may be triggered.

[0063] For example, Table 2 shows (part of) the post-accident monitoring instrument data of a nuclear power plant with a four-column redundant configuration.

[0064] Table 2 - Monitoring instrument data after nuclear power plant accident

[0065]

[0066]

[0067] As shown in Table 2, the steam generator water level (wide range) meter and the steam generator water level (narrow range) meter are only applicable to operating modes 1, 2, and 3. The purpose of operating mode judgment is to provide input to determine whether the current operating mode requires the meter to be operational, that is, whether the meter is required to be operational.

[0068] S102 : Determine the operability of each instrument in the target instrument group based on the instrument status information and instrument measurement data information of each instrument.

[0069] The operability of an instrument is an indicator used to measure whether the instrument can perform its corresponding instrument function. It is understood that a system, subsystem, column, component or device is operable if it can perform its specified safety function and all necessary measuring instruments, controls, normal or emergency power supplies, cooling water and sealing water, lubrication and other auxiliary equipment to perform its specified safety function are also able to perform their related supporting functions.

[0070] Typical faults that can lead to loss of instrument operability include sensor probe failure, signal jitter, signal overrange, and drift. Specifically, during the instrument signal acquisition and processing process, the digital instrumentation and control system can identify some instrument faults (such as overrange). After identifying an instrument fault, the corresponding instrument status information is marked as invalid. Other faults require cross-comparison between redundant instrument signals and the operator's engineering judgment to identify them.

[0071] like Figure 2 As shown, in one possible implementation, if the instrument status information from the digital instrumentation and control system is marked as invalid, the instrument is immediately deemed to have lost operability, meaning that the measurement data from the instrument is no longer reliable. For example, if a mid-range neutron fluence rate instrument in a column shown in Table 2 is lost, the status information for that column of mid-range neutron fluence rate instruments is marked as invalid. In another possible implementation, if the instrument data deviation is excessive, the instrument is deemed to have lost operability. Additionally, if the operator's engineering judgment indicates that the instrument is inoperable, the instrument is also deemed to have lost operability.

[0072] S103: Determine the operation restriction condition corresponding to the target instrument cluster according to the operation mode information.

[0073] Understandably, nuclear power plant technical specifications specify a series of operating constraints, which define the minimum requirements for ensuring the safe operation of nuclear power units. These constraints constitute the boundaries of the plant's normal operation. If the plant can maintain compliance with these constraints during normal operation, or if, upon discovering a safety function is inoperable, measures are taken in accordance with the constraints and completed within the specified timeframe, the plant's safety level can be considered maintained. Safety functions are those necessary to ensure the safe operation of the plant, including reactivity control, core heat removal, and shielding and containment of radioactive materials.

[0074] Specifically, the operating constraints in a nuclear power plant's technical specifications include: assumptions used in safety analyses (e.g., initial reactor power, initial boron concentration), safety functions required for accident mitigation (e.g., reactor emergency shutdown, emergency boronization, and emergency water supply), and post-accident monitoring functions (e.g., post-accident monitoring instruments such as core cooling monitoring). These instruments involve a large number of instruments, which are essential for achieving safety functions and are classified as safety-level instruments. Therefore, the technical specifications require the establishment of corresponding operating constraints for these instruments. These operating constraints include: developing measures for instrument inoperability events, with a time limit for completion. The corresponding measures define the actions required to ensure unit safety is not degraded in the event of instrument inoperability, and the completion time is the total time allowed to complete a required measure.

[0075] Specifically, if the current operating mode requires these instruments to be operational, the technical specification will define operating restrictions for the instruments. When one or more instruments are not operational, an event corresponding to the operating restriction will be triggered.

[0076] S104 , determining the operational safety of each instrument in the target instrument group according to the operability of each instrument and the operational restriction condition corresponding to the target instrument group.

[0077] Among them, the operational safety of each instrument in the target instrument group includes safe operation and unsafe operation; safe operation means that the operability of each instrument in the target instrument group does not trigger the event corresponding to the operation restriction condition; unsafe operation means that the operability of each instrument in the target instrument group triggers the event corresponding to the operation restriction condition, and corresponding measures need to be taken.

[0078] Specifically, the instrument availability determination step in S101-S103 can identify the number of inoperable instruments. Within the operational restriction conditions, different numbers of inoperable instruments correspond to different events, corresponding to different levels of instrument operational safety. For example, this embodiment records corresponding events based on the number of inoperable instruments. Table 3 lists (partial) events defined within the operational restriction conditions for post-accident monitoring instruments.

[0079] Table 3 - Events corresponding to monitoring instruments after an accident

[0080]

[0081] In the above-mentioned instrument monitoring method, the operability of each instrument in the target instrument group is automatically judged based on the instrument status information and instrument measurement data information of each instrument; further, the operating restriction conditions corresponding to the target instrument group are determined based on the operating mode information; under different operating modes, based on the operability of each instrument, it is judged whether each instrument meets the operating restriction conditions under the corresponding operating mode, thereby identifying the operating safety of each instrument under different operating modes to ensure the operating safety of the nuclear power plant.

[0082] This embodiment provides an optional method for obtaining instrument status information, instrument measurement data information, and corresponding operating mode information for each instrument in the target instrument group, that is, a method for refining S101. The specific implementation process may include: obtaining real-time operating data of the unit; and determining the instrument status information, instrument measurement data information, and corresponding operating mode information for each instrument in the target instrument group based on the real-time operating data.

[0083] Specifically, the digital instrumentation and control system (Distributed Control System, DCS) of a nuclear power plant can realize real-time monitoring of the operation of the unit. The real-time operation data of the unit includes instrument status information, instrument measurement data information, and parameter data used to determine the operation mode of the unit. For example, the parameter data used to determine the operation mode of the unit include: reactivity state, core thermal power, average temperature of the reactor coolant, etc.; therefore, based on the real-time operation data, the instrument status information, instrument measurement data information and corresponding operation mode information of each instrument in the target instrument group can be determined.

[0084] In one embodiment, an optional method for determining that the instrument has lost operability based on excessive deviation of the instrument data is provided; Figure 3 As shown, this embodiment provides an optional method for determining the operability of each instrument in the target instrument group based on the instrument status information and instrument measurement data information of each instrument, that is, it provides a method for refining S101. The specific implementation process may include:

[0085] S301 : Determine a valid instrument from each instrument in a target instrument group according to the instrument status information of each instrument.

[0086] S302: If the number of valid meters is greater than two, determine reference data information based on meter measurement data information of each valid meter.

[0087] Specifically, the average value of the instrument measurement data of all valid channels is calculated, and the average value is used as the basic data information.

[0088] S303: Determine the operability of each valid meter according to the deviation value between the meter measurement data information of each valid meter and the reference data information.

[0089] like Figure 4 As shown, specifically, the measurement data information of each instrument is then compared with the basic data information. If the deviation is too large (for example, ≥5%), the instrument is marked invalid and considered to have lost operability. The baseline data information (average value) after eliminating the invalid instrument is then recalculated, and a new round of deviation comparison process is performed until only two columns of instruments remain.

[0090] For example, taking four redundant meters as an example, assuming that the measurement data of the four meters are valid (the meter status information is not marked as invalid), the average value of the measurement data of the four meters is calculated, and then the measurement data of each meter is compared with the average value. If the deviation of the measurement data of an instrument from the average value is within the set range (for example: Figure 4 If the deviation does not exceed 5%), continue to the next instrument for deviation comparison; if it is found that the measurement data of an instrument deviates too much from the average value (for example: Figure 4 If the deviation exceeds 5%, the instrument is marked as inoperable and invalid. The invalidated measurement data is then discarded, and the average value is recalculated. The operability of all instruments not marked invalid is then re-evaluated based on the deviation. This continues until the deviation between the measurement data of all instruments not marked invalid and the average value is within the set range or the number of instruments not marked invalid does not exceed two.

[0091] Taking four columns of redundant instruments as an example, after judging the operability of the instruments based on the deviation, the possible termination situations are: (1) All four columns of instruments are operable: All four columns of redundant instruments are valid, and the deviations are within the set range; (2) Three columns of instruments are operable: One instrument is marked as inoperable, and the remaining three columns of instruments are valid and the deviations are within the set range; (3) At least two columns of instruments are marked as invalid, that is, the number of instruments not marked as invalid does not exceed two.

[0092] Furthermore, if the deviation result is greater than a reference deviation value (eg, ≥5%), the deviation result is sent to a terminal corresponding to the operation and maintenance personnel to receive feedback from the operation and maintenance personnel on the operability of the instrument.

[0093] Specifically, if the operator determines that an instrument is faulty, the instrument is deemed inoperable.

[0094] It is understandable that operators can make judgments based on all available information and engineering and operating experience. For example, they can compare and analyze the instrument measurement data with other instruments that indirectly reflect the physical meaning of the instrument parameters to comprehensively judge the instrument availability (for example, in the example in Table 2, the core reactivity level can be comprehensively evaluated based on the power range neutron injection rate channel measurement data, the primary circuit boron concentration, the control rod position, the boron differential value, the control rod differential value, etc. The results of the comprehensive evaluation can be compared with the measurement data of the intermediate range neutron injection rate to analyze whether the two are consistent, so as to judge the operability of the intermediate range neutron injection rate).

[0095] In one embodiment, if the number of instruments not marked as invalid does not exceed two, the instrument availability is determined under special circumstances. If only one instrument is left, the operator determines whether the instrument is faulty. If only two instruments are valid, the determination is made according to the following formula:

[0096] |Instrument measurement data A - Instrument measurement data B|≤2×Σ

[0097] Where Σ is the instrument measurement error.

[0098] That is, if the number of valid meters is two, the operability of each valid meter is determined based on the meter measurement data information of each valid meter and a preset reference error.

[0099] Specifically, if the absolute value of the difference between the two instrument's measured values ​​is no greater than 2 times Σ, the two instruments can be considered operational. If the absolute value of the difference between the two instrument's measured values ​​is greater than 2 times Σ, the operator can determine whether the instrument is faulty.

[0100] In one embodiment, for nuclear power units using a digital instrumentation and control system (DCS), real-time collection of instrument measurement data and real-time determination of instrument status are achieved. The instrument monitoring method involved in this embodiment can be integrated into the existing DCS of a nuclear power plant, or used as an independent system to obtain relevant data from the DCS. Figure 5 A system implementation example of obtaining real-time data from DCS to determine instrument availability is given.

[0101] exist Figure 5 In the system, real-time unit operating data, including instrument measurement data and instrument status information, is sent through the firewall to the system. The system's information acquisition module collects and processes the data, then determines instrument operability and operating mode, and records corresponding events, required measures, and completion time. The system also provides a human-machine interface to display necessary information and provide an interface for human intervention.

[0102] Leveraging the advantages of digital instrumentation and control systems, by extracting measurement data and status information of all safety-level instruments from the digital instrumentation and control system in real time, and then formulating corresponding operability judgment criteria for these instruments, the operability of the instruments is comprehensively judged from aspects such as DCS instrument effectiveness monitoring, deviation comparison between each instrument's measurement value and the average value of redundant instrument measurements, and measurement deviation between different instruments. Combined with the engineering judgment of the operating personnel, the operability of the instruments is automatically judged, thereby achieving the purpose of automatically identifying events corresponding to instrument-related operating restrictions, ensuring the automatic, accurate, and real-time identification of events corresponding to instrument-related operating restrictions, and thus ensuring the safe operation of nuclear power plants.

[0103] It should be understood that, although the steps in the flowcharts of the above embodiments are shown in sequence as indicated by the arrows, these steps are not necessarily performed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the flowcharts of the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily to be performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of steps or stages in other steps.
