| 摘 要： | 使用改进的系统程序RELAP5建立了一个混合能谱超临界水堆(SCWR-M)模型。为研究混合能谱超临界水堆失流事故特性，以获取缓解混合能谱超临界水堆失流事故的措施，选取反应堆冷却剂泵惰转时间、压力容器上部储水空间容积和安注流量作为主要参数进行分析。研究表明，混合能谱超临界水堆系统的设计是可行的。反应堆冷却剂泵惰转15 s，压力容器上部水空间容积大于27 m3，以及安注流量高于系统满功率稳态流量的5%是缓解混合能谱超临界水堆失流事故的主要措施。

| Abstract: | Based on a revised version of RELAP5,a model of the mixed spectrum supercritical water cooled reactor(SCWR-M) system was established.Some important parameters were chosen as the main parameters to analysis the transient behaviour of SCWR-M and fix mitigation measures during loss of flow accident(LOFA).Reactor coolant pump(RCP) coast-down time of more than 15 seconds,RPV upper water volume of more than 27 m3,and safety injection of more than 5% of the system design flow are the main mitigation measures for the LOFA of SCWR-M. |
