A Method for Integrity Assessment of Nuclear Power Plant Commissioning Test Items

Abstract

The invention discloses a method for completeness evaluation of nuclear power plant debugging test projects. The completeness evaluation is performed in four dimensions including a nuclear safety regulatory guideline dimension, a system and machine unit function decomposition dimension, an accident analysis dimension and other reactor type nuclear power plant transverse comparison dimensions; through the four-dimension test project completeness evaluation, the obtained test projects are integrated; relatively complete test projects can be obtained. The test projects evaluated by the invention conform to the requirements of the Chinese nuclear safety regulatory guideline; the verification on the response event sequence of accidents in the nuclear power plant safety probability analysis is included; the important significance is realized on the overall verification of the nuclear power plant design function and requirements and the guarantee of safe and reliable operation of the machine unit.

Description

technical field [0001] The invention relates to a method for evaluating the integrity of nuclear power plant debugging test items, which can obtain complete nuclear power plant debugging test items, and belongs to the field of nuclear power plant debugging. Background technique [0002] The third-generation PWR passive nuclear power plants, such as AP1000, CAP1400, etc., adopt the passive safety concept, and the safety factor has been greatly improved. Relying on the project Sanmen and Haiyang AP1000 nuclear power units are the first and the first three AP1000 reactors in the world. There is no ready-made AP1000 commissioning experience to learn from, especially the AP1000 adopts the passive safety concept, and there is no precedent for unit commissioning. The integrity of the AP1000 commissioning test project, the first reactor test project, and the first third reactor test project are insufficiently evaluated, and there are relatively large disputes in nuclear safety super...

Problems solved by technology

[0004] According to the results of the National Nuclear Safety Administration (NNSA)'s review of the commissioning program for the first phase of the Sanmen and Haiyang supporting projects, there are certain omissions in the commissioning and test projects of Sanmen and Haiyang; The review of the outline test program is to a large extent to propose the missing items of the test items by comparing the two with each other. There is a lack of a complete list of benchmarking test items, and it is difficult to ensure the integrity of the test items.
