摘要: 本文以昌江核电厂概率安全分析(PSA)的结论为基础,通过研究相关运行事件/事故,梳理建设过程中不符合项或发生过的事件,筛选厂址区域自然灾害以及外部环境事件,收集国内、外其他核电厂已发生的事件/事故,初步选择了代表性与针对性强的事件/事故,选择合适的事故序列进行组合,形成若干个包络性较强的主事故序列,同时编制了部分可随时插入(在不影响主事故进程的前提下)的情景片段,可组合形成若干个随时间演变的完整事故情景。本文给出了事故情景个例分析,并就如何提高事故情景设计的合理性和针对性提出了建议。

Abstract: Besides the review of relevant operation events/accidents, the nonconformities happened in plant construction, the screening of local natural disasters and external events, and the reference of incident/accidents occurred in other nuclear plants,the events/accidents with high representation and pertinence were preliminarily chosen based on the conclusion of the probabilistic safety analysis (PSA) of the Changjiang nuclear power plant. Based on the studies above, several complete accident sequences were formed. Small accident scenarios were compiled, which could be inserted to the complete accident sequences at any time with no interruption. Examples of scenarios and suggestions were given to improve the rationality and pertinence of the design of accident scenario.

Key words: PSA, nuclear power plant, nuclear accident, emergency exercise, accident scenario
