摘要

事件树分析是核电厂概率安全分析中最常用的方法之一，在运用该方法进行定性定量分析时首先需要将模型中的序列/后果链接形成相应的序列/后果故障树，该过程中一般通过边界条件和成功分支处理准则等设置来保证最终故障树达到指定要求。为解决由于复杂边界条件设置导致的最终故障树结构冗余问题，本文提出了一种基于结构重用的事件树复杂边界条件处理方法。经大量实例验证，该方法完全正确，可显著提高概率安全分析软件事件树分析速度，并为核电厂的实时风险分析提供了技术基础。

Abstract

Background:

Classical fault-tree link method is usually used in event-tree analysis to convert sequence/consequence into final sequence/consequence fault-tree models

during which boundary condition and success branch treatment are set to ensure the final model satisfying certain requirement.

Purpose:

This study aims to solve the structure redundancy problem caused by complex boundary setting in the final fault trees.

Methods:

Based on structure reuse

a processing method of complex boundary condition in event-tree is proposed.

Results:

Processing speed of this method is significantly improved for event tree analysis under the condition that the qualitative and quantitative result is identical.

Conclusion:

This complex boundary condition processing method provides an efficient solution for real time risk analysis of nuclear power plant.
