摘要/Abstract

摘要： 简单合理的物项安全分级,不仅可以提高设施的安全性,而且还可以减少审评双方的分歧,降低营运单位和设计单位的工作量。在分析国内外核动力装置采用核安全功能进行物项安全分级和乏燃料后处理设施采用剂量准则开展物项安全分级的基础上,研究提出了采用放射性物质包容量开展核燃料循环设施的物项安全分级的方法,并采用“未缓解释放”的事故分析方法,将放化安全一级(250 mSv)和放化安全二级(5 mSv)对应的剂量准则转化为放射性物质包容量限值。

关键词: 核燃料循环设施, 安全分级, 未缓解释放, 放射性物质包容量

Abstract: Items safety classifications which is simple and reasonable, not only can improve the safety of facilities, but also can narrow differences between the reviewers and operators, and reduce workload of the operator and designer's. This paper analyses the usage of nuclear safety functions method for safety classification of items for nuclear power plant, and the adoption of dosage guidelines to safety classification of items for spent fuel reprocessing facility, and then proposes a method of radioactive materials pack capacity to classify the safety of items for the nuclear fuel cycle facilities. Using the “unmitigated release” accident analysis method, the dose criteria of radiochemical safety 1 (250 mSv) and radiochemical safety 2 (5 mSv) are able to be translated into radioactive material package capacity criteria.

Key words: nuclear fuel cycle facility, safety classification, unmitigated release, radioactive materials pack capacity
