ITER双功能液态锂铅实验包层系统故障模式影响分析

Failure mode and effect analysis of the dual functional lithium lead test blanket module system for ITER

实验包层模块允许放置在ITER中实验的前提是其对ITER的安全以及对工作人员和环境不构成显著影响。ITER要求各参与方的实验包层模块在实验前必须提交安全分析报告,进而获取安全许可证。在中国双功能锂铅实验包层模块(DFLL-TBM)设计基础上,采用了故障模式影响分析(FMEA)方法对DFLL-TBM进行了安全评估与分析,得到所有可能导致严重后果的假设始发事件,验证了确定论安全分析所选择的三个参考事件可以包络所有的假设始发事件。

As a key safety-related component of ITER,the detailed safety analysis of Chinese Dual-Functional Lithium Lead-Test Blanket Module （DFLL-TBM） system is necessary to be performed. Failure Mode and Effects Analysis （FMEA） has been applied to perform the safety analysis of DFLL-TBM. This paper describes the process of FMEA studies on DFLL-TBM system. All safety-related PIEs are identified, and a set of PIEs recommended to be taken into account in further deterministic transient analyses are defined for both SLL and DLL blanket concepts separately.
