中文摘要： 始发事件分析评价是核安全分析及概率安全分析的开端，具有关键作用，并对反应堆的设计具有完善和指导作用。压水堆的始发事件分析评价的方法主要采用参考已有清单和报告，运行经验，工程评价和逻辑图分析的方法。目前始发事件分析评价可参考的和运用的资料方法主要针对压水堆展开，但对于固态燃料熔盐堆没有系统的分析理论和参考。随着固态燃料熔盐堆研究设计的进展，需要在已有压水堆始发事件分析理论方法基础上进一步发展研究固态燃料熔盐堆始发事件分析，据此提出固态燃料熔盐堆的初步始发事件清单和分析方法。结合事故分析计算，进行固态燃料熔盐堆始发事件主逻辑图分析研究，探索固态燃料熔盐堆概率安全评价始发事件清单和分析方法，对阐明固态燃料熔盐堆始发事件分析规律有重要意义，为我国钍基熔盐堆研究设计和安全分析奠定基础。

英文摘要： The initiation events analysis and evaluation were the beginning of nuclear safety analysis and probabilistic safety analysis, and it was the key points of the nuclear safety analysis. The main methods for the initiation events analysis are reference to existing lists and reports, operating experience, project evaluation and logic diagrams analysis. Currently, the initiation events analysis method and experiences both focused on pressurized water reactor（PWR），but there are no general theories for Fluoride Salt-Cooled High Temperature Reactor (FHR). With FHR’s research and development, the initiation events analysis and evaluation was increasingly important. The PWR’s analysis theories and methods would be developed for the FHR. Based on the FHR’s design, the theories and methods of initiation events analysis would be researched and developed. The logical analysis and accident analysis calculation method would be combined to study FHR’s initiation events. The theory of analysis would be developed and the analysis method system would be built. Finally, the preliminary initiation events list of FHR will be given and researched. The results would help TMSR’s reactor designs and nuclear safety analysis.
