风险依据型决策方法在核电厂维修中的应用

Application of Risk-Informed Decision-Making in Maintenance of NPPs

分析了核电厂建立在事故分析确定论方法基础之上的运行技术规范 ,对维修实施过程进行核安全管理的局限性。介绍了 90年代后期在核电发达国家提出的风险依据 (Risk Informed)安全管理的决策原则 。

The operation technical specifications used in many nuclear power plants are developed based on the deterministic method of accident study. Analyzing the limitation of these specifications on the nuclear safety management when implementing maintenance, the principle of risk informed nuclear safety management is introduced, which was brought forward in the countries with well developed nuclear power plants late in 1990s.At last, the applicable scope of risk informed decision making principle and suggestion when managing maintenance of a nuclear power plant are raised.
