Embodiment 1

[0069] A specific embodiment of the present invention discloses a method for identifying the applicability of nuclear power plant safety-level instrument and control system equipment, such as figure 1 shown, including the following steps:

[0070] S1. Conduct quality assurance process analysis. Judging whether the quality assurance conditions of the equipment of the completed appraisal test project and the equipment of the target project are consistent; if not, it is judged that the equipment of the target project is not applicable to the target project.

[0071] S2. If the quality assurance conditions of the equipment that has completed the appraisal test project and the equipment of the target project are consistent, analyze the system function performance, product model and version, test conditions, and application hardware configuration of the two in turn, and identify the functional performance of the system in the equipment of the target project , product model and vers...

Embodiment 2

[0075]Optimizing on the basis of Example 1, such as figure 2 As shown, step S1 can be further refined into the following steps:

[0076] S11. Determine all factors that may affect the suitability conclusion in the quality assurance process, and the factors include document control, procurement control, item control, process control, inspection and test management, and non-conformity item control.

[0077] S12. Determine the quality assurance program that includes the above factors and meets the requirements of the target project.

[0078] S13. In view of the above factors, compare the target project equipment / completed appraisal test equipment with the quality assurance program one by one to judge whether both follow the quality assurance program, and whether the quality assurance control methods and levels adopted by the two are consistent.

[0079] Preferably, step S12 is based on the HAF003 "Nuclear Power Plant Quality Assurance Safety Regulations" regulations and relevan...

Embodiment 3

[0115] A specific example of applying the method described in Example 2 for applicability analysis is given below.

[0116] The first step is to analyze the quality assurance process. According to the safety-level product design and manufacturing quality assurance program, the quality assurance level of the target project equipment is Q1, and its quality management system requirements meet HAF003. The quality control is the whole process quality supervision, and the completed Verify that the safety-level product design is consistent with the manufacturing quality assurance requirements. Therefore, proceed to step S2.

[0117] In the second step, the system function performance analysis is carried out first. The target project equipment (FirmSys platform) includes conditioning and isolation functions, analog IO functions, digital IO functions, IO communication functions, computing processing functions, hot standby redundancy functions, and data link functions. 9 major function...

Abstract

The invention relates to a method for evaluating the equipment applicability of a nuclear power plant security level instrumentation and control system, belongs to the technical field of nuclear powerplant security level instrumentation and control, and aims at solving the problem that in the prior art, an existing evaluation test result cannot be effectively applied to a new project for applicability analysis. According to the method, analysis is conducted on the basis of a result of project equipment completing an evaluation test, whether or not target project equipment meets application requirements is judged in theory, and inapplicable aspects are subjected to supplementary evaluation; the equipment applicability evaluation analysis dimensions, that are, the five dimensions of the quality assurance process, the system function performance, the product model and version, the test conditions and the application hardware configuration are defined, evaluation criteria for various dimensions and a difference item processing criterion are defined, manpower and material resources needing to the input for an evaluation test are greatly reduced, the evaluation cycle is shortened, precious time is won for successful conduction of a target project, and equipment evaluation result reusing of the same product under different application requirements can be achieved.

Description

technical field [0001] The invention relates to the technical field of safety-level instrumentation and control of nuclear power plants, in particular to a method for appraising the applicability of safety-level instrumentation and control system equipment of nuclear power plants. Background technique [0002] In order to ensure that the electrical equipment of the safety-level I&C system of a nuclear power plant performs its functions as required, the relevant standards require that the equipment must pass the quality appraisal. At present, the quality appraisal of equipment generally adopts the type test method. [0003] When the certified product has passed the certification result of a certain project type test, and when it is applied to a new project, once the application environment, product type or version, etc. change, all the certified products will be put into the type test again, which will cause manpower, Waste of time and economic cost, and affect the project s...
