Transient Thermal Analysis for Safety of Test Blanket Module for ITER

Institute of Plasma Physics, Chinese Academy of Sciences, Hefei, Anhui, 230031, China

摘要: 在中国向ITER (International Thermonuclear Experiment Reactor)实验包层工作组提交的双功能锂铅实验包层模块(DFLL-TBM)设计分析的基础上,通过对DFLL-TBM系统相关的瞬态事故如真空室内部冷却剂泄漏、TBM (实验包层模块)内部冷却剂泄漏以及真空室外部冷却剂泄漏事故进行计算分析,评价DFLL-TBM对ITER在热工方面对安全的影响。结果表明:当发生瞬态事故时,DFLL-TBM有能力通过热辐射将余热排出,且包层结构不会熔化。DFLL-TBM可满足ITER在热工方面对安全的要求。

Abstract: Based on analyses of the Dual Functional Lithium Lead-Test Blanket Module（DFLL-TBM） submitted to International Thermonuclear Experimental Reactor（ITER） Test Blanket Working Group（TBWG）,the influence to ITER safety was evaluated by analyzing the typical transient accidents related to DFLL-TBM system.The transient accidents include invessel TBM coolant leaks,in-TBM breeder box coolant leaks and exvessel TBM coolant leaks.The results show that DFLL-TBM has the ability to remove the decay heat by thermal radiation when transient accidents occur,and the structures of the TBM would not melt.The DFLL-TBM can meet the ITER safety requirements on thermal aspect.
