摘要(Abstract):

依据HAF法规和核电厂质量管理标准,结合ASME核电规范与标准,充分考虑核主泵零部件的功能性、复杂性、成熟性、利用率和造价成本,对"华龙一号"核主泵的质保等级和安全分级的划分进行了分析。质保和安全等级的划分可以降低生产制造活动的造价成本,并适当减少质量保证活动管控所需的人力和物力。本文根据ASME设计规范、功能、承载应力及是否与介质接触4个方面提出质保等级的定义原则,按照ASME规范第Ⅲ卷NB,NC,ND分卷的要求提出安全分级的定义原则。对比质保等级和安全分级的划分原则,确定质保等级不低于安全等级。
According to HAF regulations and the quality management standards of the nuclear power plant,in combination with ASME nuclear power codes & standards and by fully considering the functionality,complexity,maturity,utilization rate and cost of the components,the division criteria of the quality assurance level and safety classification for the HPR1000 RCP are analyzed.The division purpose is to reduce the cost of the manufacturing activities and decrease the labor and material resources required for the control of quality assurance activities appropriately.Based on such four aspects as of the ASME design codes,function,stress retaining and whether it is in contact with the medium,the definition principles of the quality assurance level are proposed,and the definition principles of the safety classification are proposed according to the requirements of ASME Ⅲ Division 1-Subsection NB,NC and ND.The division principles of the quality assurance are compared with those of the safety classification to ensure that the quality assurance level is not lower than the safety classification.
