Problems solved by technology

For example: safety issues - some guidelines are of high safety importance, but strict regulations and actions are not given in the management process, which may easily lead to insufficient attention of personnel and lead to safety impacts
Economical issues - certain criteria have a large safety margin, if excessive requirements are given in the management process, it is easy to consume the management resources of the power plant and bring unnecessary management burden to the power plant, which is not conducive to economic growth

Embodiment 1

[0061] This embodiment is used to illustrate the classification by detailed rules, as shown in Table 3 below, it is to classify the criterion of the isolation valve "closing of 1TEP053VP-2TEP054VP". According to step S2, first use the detailed rules to judge, because it belongs to the isolation valve, so look up the detailed rules of the valve class in Table 2, since this embodiment is for the closure of 1TEP053VP-2TEP054VP, so the content of 7.8 in Table 2 can be used Based on the criterion for judging the "closing of 1TEP053VP-2TEP054VP", according to 7.8 in Table 2, it can be seen that the criterion of "closing of 1TEP053VP-2TEP054VP" belongs to level A.

Embodiment 2

[0067] This embodiment is used to illustrate classification by general principles, as shown in Table 4 below, according to step S2, first use the detailed rules to judge, because it belongs to the sensor, so find the detailed rules of the sensor class, and according to the analysis of the upstream file in step S1 It can be seen that there is no relevant standard for its function in the detailed rules of the sensor class, so the detailed rules cannot classify the criteria in Table 4, so the general principle is adopted, and it can be determined from the analysis of the upstream file in step S1 that it should refer to the general The 7th in the principle, so the criterion of this embodiment belongs to the B level.

Abstract

The invention provides a grading management method for a nuclear power plant periodic test supervision requirement. The method comprises following steps: S1: querying upstream relevant document data and performing safety and availability analysis to all criterions in the supervision requirement; S2: determining the grades of all criterions of the supervision requirement according to detailed rules and regulations, general principles and grade definitions on the basis of the analysis result of step S1; S3: comparing the grading result with the grading result of corresponding criterions of a reference power station, and rechecking the grading result which is different from that of the reference power station. According to the method, safety and availability analysis are performed to the criterions, then safety grading is performed to each test criterion according to the detailed rules and regulations, general principles and grade definitions, the criterions can be applied in management and control for strengthening important nuclear safety relative functions or devices after the criterions are graded to increase and enhance the safety management level of power stations.

Description

technical field [0001] The invention relates to the field of periodic test supervision and safety management, in particular to a method for hierarchical management of nuclear power plant periodic test supervision requirements. Background technique [0002] In terms of design, the safety of nuclear power plants is based on defense in depth, which is divided into three levels in the design: prevention, surveillance detection and action. Periodic testing is the main means of the second level, through regular inspection of important safety equipment and systems to detect and ensure the availability of these functions, equipment and systems. At present, there are two types of periodic test supervision requirements at home and abroad. [0003] The first category is the combination of supervision requirements and technical specifications (periodical test supervision items are not listed separately, but are described and stipulated in the technical specifications as part of the con...
