摘　　要：核动力厂的设计中通过对物项进行安全分级,来确保物项的设计、制造、建造等满足适当的要求,达到与其执行的功能相符的可靠性。本文简要介绍了根据安全重要性对核动力厂物项进行安全分级的方法以及应考虑的因素。针对物项安全分级中应考虑的未能执行某一安全功能的后果,使用核动力厂不同工况下对公众和工作人员的剂量准则来划分“高、中、低”后果。通过研究提出放射性“高、中、低”后果定量化的建议,以使得该方法在用于核动力厂物项安全分级时更具有可操作性。In the design of nuclear power plant,the safety classification of items is carried out to ensure that the design,manufacturing and construction of the items meet appropriate requirements and that the reliability consistent with their functions can be achieved.This paper briefly describes the method of safety classification of nuclear power plant items according to safety importance and the factors that should be considered.For the consequences of failing to perform a safety function that should be considered in the safety classification of the items,the dose criteria for the public and staff under different working conditions of nuclear power plant are used to divide them into high,medium and low consequences.Through the study,some suggestions on the quantification of high,medium and low radioactive consequences are put forward so as to make this method more operable in the safety classification of nuclear power plant items.

关 键 词：核动力厂物项 安全分级 放射性后果 剂量限值
