Research on Quality Assurance of Raw Materials for Nuclear Power Equipment

Abstract

Abstract In terms of quality management of raw materials for nuclear power equipment, equipment manufacturers implement quality management for raw materials according to different standards, to ensure the quality and reliability of nuclear power equipment. However, through some typical cases, it is found that many manufacturers do not effectively operate the quality assurance system in the equipment raw material quality management, and there are not enough anti-counterfeiting measures, resulting in unqualified raw material quality affecting the quality of nuclear power equipment. For example, when a manufacturer purchased ASME code grade bars for manufacturing nuclear valves, the raw material supplier forged part of the test reports from the third-party laboratory to make the results meet the requirements of the standard. However, the manufacturer did not find the problem in the procurement process. By comparing the quality assurance requirements of nuclear power units under different standards, this paper analyzes the problems in the process of raw material purchasing and quality management, combined with some measures and requirements to prevention CFSI, puts forward some suggestions for optimizing the quality assurance of raw materials for nuclear power equipment.
