| 摘 要： | 动态概率风险评价的研究方法理论性强、技术难度高、掌握运用困难,从而限制了其实际应用。在Cassini任务PRA的基础上,对事件序列图方法进行拓展和完善,采用事件序列图方法进行反应堆动态概率风险评价,研究反应堆事故中动态因素对系统和事故发展进程及其后果的影响。通过对反应堆冷却剂系统失流事故的分析,阐述事件序列图法在反应堆事故分析中的应用过程。事件序列图分析提供了足够的系统动态信息,易于工程技术人员理解、掌握和应用,适合于大型系统的动态概率风险评价。

| Abstract: | The methodologies used for dynamic probabilistic risk assessment (DPRA) are highly academic and they are difficult to command, which restrict the practical application. The event sequence diagram (ESD) method is extended and perfected based on the Cassini mission PRA. And then ESD method is used for the reactor DPRA, in order to study the effects of dynamic factors on the systems and the accident progression and consequences. The loss-of-flow accident is taken for example to show the application of ESD to t... |
