基于概率安全评价重要度分析的提升核电厂设计阶段经济性研究

Study of Nuclear Power Plant Economy Improvement during Design Phase Based on Importance Analysis of Probabilistic Safety Assessment

概率安全评价(PSA)是以概率论为基础的风险量化评价技术,在核电厂设计阶段,当前通常用于评价核电厂的风险、发现设计上的薄弱环节、提升电厂安全性。本文从PSA重要度和敏感性分析结果的角度,探讨在核电厂设计阶段采用PSA提升经济性的方法。

Probabilistic Safety Assessment(PSA)is a technique of risk quantification based on probability theory,and it is applied for assessing risk of plant,detecting weakness of design,and improving safety during the design phase of nuclear power plant.The methodology of improving economy during design phase of nuclear power plant(NPP)is discussed from the view of the results for PSA importance and sensitivity analysis in this paper.
