Embodiment Construction

[0017] The present invention will be further described below in combination with specific embodiments.

[0018] Such as figure 1 As shown, the nuclear power plant system periodic test project analysis and design method provided by the present invention comprises the following steps:

[0019] (I) Screening out the systems that need periodic tests in the nuclear power plant system;

[0020] (II) Determine the items and contents of the periodic test for the system that needs to be tested regularly, and determine the acceptance criteria that the equipment or components that perform different functions involved in each item should meet when performing the periodic test;

[0021] (Ⅲ) Determine the test period for the equipment or components involved in each item to perform periodic tests, and establish periodic test notes for each item.

[0022] The specific implementation of step (I) of the present invention is: according to the functions performed by each system of the nuclear p...

Abstract

The invention relates to a nuclear power plant system regular test project analysis design method. The method comprises the following steps: (I), screening systems needing regular tests in a nuclear power plant system; (II), for the systems needing the regular tests, determining projects and content of the needed regularly conducted tests, and determining acceptance criteria which devices or parts which are determined by the projects for executing different functions should satisfy when the regular tests are executed; and (III), determining test periods of the devices or parts of the projects in executing the regular tests, and at the same time, establishing regular test notes according to needs of the test projects. According to the invention, based on functions and configuration executed by systems, the systems needing the regular tests are screened, and according to the function execution reliability, the projects and the content executing the regular tests are analyzed and designed, such that it can be ensured that the safety, and safety-correlated systems, devices and functions can be regularly examined, accordingly, it is ensured that the functions are at normal states, and at the same time, the feasibility and the validity of executing the regular tests by operation personnel can also be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of periodic tests of nuclear power plant systems, and in particular relates to an analysis and design method for periodic test items of nuclear power plant systems. Background technique [0002] At present, the analysis and design of the regular test content, cycle, and acceptance criteria for the safety and safety-related systems and equipment of typical domestic PWR nuclear power plants mainly rely on the design experience of foreign power plants of the same type, without analyzing the setting items from the source, cycle, acceptance criteria approach. Foreign power plants of the same type have formulated a series of upstream support documents for periodic tests as supplementary explanatory documents for periodic tests in response to the feedback from the experience of periodic tests of nuclear power plants. [0003] The periodic test items, cycles and guidelines of nuclear power plants are important upst...
