[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Embodiment 1:

[0022] When an accident occurs in a nuclear power plant, the operator usually performs a series of operations according to the steps of the paper accident procedures to mitigate the consequences of the accident. Digital accident procedures refer to the process of presenting paper accident procedures to operators in the form of a computer interface, and adding operation links, operation confirmations, operation screens, etc. to paper accident procedures according to the characteristics of computers. The digital accident procedures of a control point contain many display interfaces. When an accident occurs in a nuclear power plant, the operator performs relevant operations according to the steps of the digital accident procedures to mitigate the consequences of the accident. After the design of the digital accident procedures is completed, it is necessary to verify whether the designed digital accident procedures meet the requirements for safe operation of the nuclear power plant, whether there are human factors engineering deviations, and optimize the human factors engineering deviations that appear in the verification to ensure the safety of the nuclear power plant when implementing the digital accident procedures.

[0023] like Figure 1As shown, this embodiment provides a verification method for a digital accident procedure, which can be widely used in the verification of various digital accident procedures of nuclear power plants. In this embodiment, the verification method is specifically described by taking the digital accident procedure "Steam Generator Heat Transfer Tube Rupture and Loss of Water (Subcooling Recovery)" of a certain unit as an example. The verification method of the digital accident procedure includes:

[0024] Step 101, determining the verification object of the digital accident procedure, the verification object includes the human-machine interface and display interface of the control point involved in the digital accident procedure.

[0025] The control points involved in the digital accident procedures usually include the main control room and the remote shutdown station, that is, the verification method of the digital accident procedures in this embodiment is applicable to verifying the digital accident procedures in the main control room and the remote shutdown station. In this embodiment, the verification objects are the human-machine interfaces in the main control room and the remote shutdown station involved in the accident procedure "Steam Generator Heat Transfer Tube Rupture and Loss of Water (Subcooling Recovery)" and the display interface of the software.

[0026] Step 102, according to the verification requirements of the digital accident procedure, verify the verification object of the digital accident procedure to obtain the human factors engineering deviation occurring during the verification process.

[0027] Specifically, step 102 includes steps S21-S23.

[0028] Step S21, determining the verification requirements of the digital accident procedures.

[0029] Specifically, determine the standards and design criteria that the digital accident procedures should meet, wherein the standards and design criteria include NUREG-0700 "Guidelines for Human-Machine Interface Design Review", HAF J0055-1995 "Human Factors Engineering Principles for Nuclear Power Plant Control Room Design", NB20061-2012 "Application of Human Factors Engineering in Nuclear Power Plant Systems, Equipment and Facilities", GB / T 13630-1992 "Design of Nuclear Power Plant Control", etc., or relevant internal design criteria compiled according to the above standards. Determine its verification requirements according to the specific digital accident procedures to be verified. In this embodiment, the digital accident procedure "Steam Generator Heat Transfer Tube Rupture and Loss of Water (Subcooling Recovery)" to be verified needs to meet NUREG-0700 "Guidelines for Human-Machine Interface Design Review" and relevant internal design criteria compiled according to the standard.

[0030] Step S22, obtaining applicable checklists and key elements according to the determined verification requirements.

[0031] In this embodiment, according to the standards and design criteria that the digital accident procedures should meet, an applicable checklist is obtained, and the checklist includes check items, item categories, requirements, requirements sources and the mapping relationship between the four. The check items include display format, display elements, display pages, display devices, etc. According to the NUREG-0700 "Guidelines for Human-Machine Interface Design Review" that the digital accident procedures for "Steam Generator Heat Transfer Tube Rupture and Loss of Water (Subcooling Recovery)" should meet, the applicable checklist is sorted out as shown in Table 1.

[0032] Table 1

[0033]

[0034] And according to the standards and design criteria that the digital accident procedures should meet, the key elements are obtained, which include important personnel actions of operators in the process of accident handling, automatic action monitoring, personnel interaction, high-load working conditions, harsh environment, tasks based on personnel cognition and knowledge, etc. Among them, for the digital accident procedure of "Steam Generator Heat Transfer Tube Rupture and Concurrent Water Loss (Subcooling Recovery)", the important personnel actions to alleviate the accident include cooling and depressurizing the main system as soon as possible, reducing the injection flow in time, and terminating the injection in time. During verification, it is particularly necessary to verify the correctness of the above important personnel actions. Automatic action monitoring includes the logical action of the control rod during shutdown, etc., which needs to be monitored and checked by the operator. Personnel interaction refers to the mutual cooperation between different operators. High-load working conditions refer to the high requirements for the speed of operation in certain accident handling, so the requirements for personnel are high, which is a high-load working condition for the operator.

[0035] Step S23, verifying the verification object of the digital accident procedure according to the applicable checklist and key elements, and obtaining the human factors engineering deviation occurring during the verification process.

[0036] Specifically, according to the applicable checklist, the verification object of the digital accident procedure is statically verified to obtain the ergonomics deviation occurring during the static verification process; and according to the applicable key elements, preset working conditions are set to dynamically verify the verification object of the digital accident procedure to obtain the ergonomics deviation occurring during the dynamic verification process.

[0037] Among them, static verification includes: according to the applicable checklist, check whether the display interface elements of the digital accident procedures meet the requirements of the checklist one by one, record the verification results, analyze the causes of non-conformities in the verification results and form human factors engineering deviations. Dynamic verification includes: by setting preset working conditions on the verification platform and simulating the personnel actions under the preset working conditions, verify whether the personnel actions and the output nuclear power plant parameter curves meet the requirements of key elements, record the verification results, analyze the causes of non-conformities in the verification results and form human factors engineering deviations.

[0038] In this embodiment, during the static verification, according to the applicable checklist, the human-machine interface elements involved in the accident procedure of "Steam Generator Heat Transfer Tube Rupture and Loss of Water (Subcooling Recovery)" are checked one by one to see if they meet the requirements of the checklist, and the check results are recorded (as shown in Table 1). For non-conforming items, artificial intelligence technology (such as expert system) can be used to analyze the causes to form human factors engineering deviations (such as Figure 2 The HED shown lacks a crossover line between the EEA busbar and the line where 002JA is located, resulting in unclear display), or a technical personnel in this field conducts a cause analysis on the non-conforming items to form an ergonomic deviation.

[0039] The verification results are divided into the following categories:

[0040] Y: Digital incident procedures meet the checklist requirements;

[0041] N: Although the digital incident procedures do not meet the checklist requirements, they do not need to be modified because they fall into the first category;

[0042] D: The digital incident procedures do not meet the checklist requirements and a HED should be generated for tracking and processing;

[0043] P: Pending, does not meet the checklist requirements and cannot be verified (e.g., some dynamic characteristics cannot be verified in static design verification and will be verified in dynamic design verification);

[0044] N / A: Checklist not applicable.

[0045] During dynamic verification, for the "Steam Generator Heat Transfer Tube Rupture and Concomitant Water Loss (Subcooling Recovery)" procedure, the preset operating conditions are: the initial operating condition is full power, one heat transfer tube of the steam generator is broken + two columns (column A and column B) medium pressure injection failure + injection box failure + two columns of low pressure injection failure + regulator safety valve opening + spray and auxiliary spray failure. It should be noted that some accident procedures can only set one preset operating condition for dynamic verification, and some accident procedures need to set multiple preset operating conditions for dynamic verification. Through operation verification on the verification platform, and judging the verification process, for example, judging whether there are errors in the display interface, whether there are errors in the personnel actions, the personnel action time, the accident mitigation effect, etc., after the verification is completed, the verification data and curves are saved, and the verification results are sorted and analyzed using artificial intelligence technology (such as expert system), or the technical personnel in this field sort and analyze the verification results to form a HED (such as Figure 3The verification platform refers to the nuclear power plant verification simulation platform, such as the full-range simulator, design verification platform, etc. The input data of the verification platform is the same as that of the real nuclear power plant, simulating the actual situation of the real power plant. When the verification is completed, the trend diagram of the nuclear power plant parameters, i.e., the verification curve, can be obtained through the verification platform.

[0046] Step 103, optimizing the digital accident procedure according to the human factors engineering deviation, so as to obtain the digital accident procedure that meets the verification requirements.

[0047] Specifically, step 103 includes: sorting, analyzing and compiling a verification report for the human factors engineering deviations that occur, the verification report includes the verification object, verification requirements, verification results, human factors engineering deviations, etc.; optimizing the digital accident procedures according to the human factors engineering deviations in the verification report. Among them, the analysis method includes the analysis implemented by artificial intelligence technology (such as expert system). Specifically, the expert system is formed by extracting the knowledge and experience data of a large number of experts in the field of nuclear power. The analysis method can also include discussions at meetings, consulting experts, calculation analysis, data comparison, etc. conducted by technicians in this field. This method can be obtained by technicians in this field according to the current conventional methods. In this embodiment, a record file of the verification process is formed by compiling and outputting a verification report, which is convenient for modification and tracing.

[0048] Optionally, after optimizing the digital accident procedures according to the human factors engineering deviations in the verification report, the verification method of the digital accident procedures further includes: verifying the optimized digital accident procedures again until no human factors engineering deviations occur, and obtaining a digital accident procedure that meets the verification requirements.

[0049] In this embodiment, when the static verification of the "Steam Generator Heat Transfer Tube Rupture and Water Loss (Subcooling Recovery)" regulation is performed, the following is formed: Figure 2 The HED shown (the EEA bus and the line where 002JA is located lack cross-over lines) is optimized for the "Steam Generator Heat Transfer Tube Rupture and Concomitant Water Loss (Subcooling Recovery)" procedure display interface for this HED. The optimization content is to modify the procedure display interface and add screen links to obtain a digital accident procedure that meets the verification requirements. Static verification is performed again for the above-mentioned optimized content until no engineering deviation occurs. In this embodiment, only the optimized content is verified again, which can narrow the verification scope, improve verification efficiency, and save verification costs. For example, during static verification, the following HED is formed: The accident procedure "Steam Generator Heat Transfer Tube Rupture and Concomitant Water Loss (Subcooling Recovery)" KECA31 Step 20 1b confirms the stabilizer water level RCP007 / 008 / 011MN, and links to the screen KOO110SEOP1. However, in the screen KOO110SEOP1, the stabilizer water level information is RCP601KM, and the procedure description is inconsistent with the screen information. Figure 3As shown in the figure, the HED formed during the dynamic verification of key factors: the regulations require regular monitoring of the main pump and link to the corresponding regular monitoring screen 1KOO901EOP, but it is found that the operator neglects to perform regular monitoring when executing the regulations, resulting in an ergonomic deviation of too low shaft seal water flow of the main pump.

[0050] The verification method of the digital accident procedure of this embodiment determines the object to be verified, and performs static verification and dynamic verification on the display interface and human-machine interface of the digital accident procedure according to the verification requirements. The static verification is mainly used to verify the consistency between the display interface and the verification requirements, and the dynamic verification is mainly used to verify whether the key elements are correct, and analyze the human factors engineering deviation formed in the verification results, and optimize the digital accident procedure according to the formed human factors engineering deviation, so as to ensure the correctness of the design of the digital accident procedure and the consistency between the implementation and the design. When an accident occurs, the nuclear power plant operator can quickly and accurately obtain relevant information on accident handling, avoid human errors, and improve the safety of the nuclear power plant. By promoting the use of the verification method of the digital accident procedure, the efficiency and quality of design and verification can be improved.
