摘要
本文对中国聚变工程实验堆(CFETR)氦冷陶瓷增殖(HCCB)包层进行热工安全分析。采用大型反应堆瞬态分析程序RELAP5对HCCB包层建模,并进行稳态分析和假设事故的模拟。计算结果表明,CFETR HCCB包层在真空室内氦气泄漏和增殖区盒内氦气泄漏事故中均未出现结构材料熔化,同时各部分的压强变化情况均未超出设计阈值,包层系统在事故发生后均能有效快速地排出余热。CFETR HCCB包层的设计满足热工安全方面的要求。
Thermal safety analysis of China Fusion Engineering Test Reactor（CFETR）helium cooled ceramic breeder（HCCB）blanket was performed.The HCCB blanket was modeled with RELAP5 which was the best estimate tool of reactor transient system,and the steady-state analysis and postulated accident calculation were carried out.The calculation results show that there is no melting component in CFETR HCCB blanket after the in-vessel LOCA and in-box LOCA happen,the pressures in all components are much lower than maximum limit,and the blanket system can remove decay heat effectively and quickly after the accident.CFETR HCCB blanket can meet the thermal safety requirement.
