<p>There are a few nuclear reactor types in China. In terms of quality management of raw materials for nuclear power equipment, equipment manufacturers implement quality management for raw materials according to different standards, so as 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, thus affecting the quality of nuclear power equipment. For example, when a manufacturer purchases ASME code grade bars for manufacturing nuclear valves, the raw material supplier forges part of the test reports from the third-party laboratory and provides them to the manufacturer to make the results meet the requirements of the standard specifications. 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 advantages and disadvantages of raw material quality assurance in different standards, combined with some measures and requirements to CFSI，puts forward some suggestions for optimizing the quality assurance of raw materials of nuclear power equipment .</p>

2021 28th International Conference on Nuclear Engineering (ICONE28)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
