摘要: 中国聚变工程实验堆(China Fusion Engineering Testing Reactor,CFETR)是一个类ITER的聚变实验堆.基于压水堆工况下的水冷包层是其包层设计的一种.使用RELAP5/MOD3.4对压水堆工况下的CFETR水冷包层做了增殖区破口事故的初步分析,详细描述了其事故进程并对事故结果做了简要分析.根据计算结果, CFETR水冷包层在事故中并没有发生面向等离子体第一壁熔化或氢气产量超过限值的情况.由于安全阀的存在,破口后冷却剂可以进入真空室.这使得包层的整体性得到了保障.此外由于真空室体积巨大,破口后其压力最终值也在安全阈值之下.

Abstract: China Fusion Engineering Testing Reactor(CFETR)is an “ITER-like” DEMO fusion reactor in China. As one of the breeding blanket candidates for CFETR, a water cooled breeder blanket based on PWR conditions has been designed. Here In-box LOCA of water cooled solid breeder blanket for CFETR based on PWR conditions was investigated by RELAP5/MOD3.4. The accident’s processes were described in detail and its results were analyzed preliminarily.According to the computational results, first wall (FW) does not melt and the production of hydrogen is lower than the limit. Meanwhile, due to the rupture disk, the flow can vent into the vacuum vessel(VV) after the accident, which ensures the integrity of the blanket. And due to the large volume of the VV, the final pressure of VV is much lower than the limit.

Key words: CFETR;water cooled solid breeder blanket, PWR condition, RELAP5/MOD3.4, In-box LOCA
