摘要
根据某小型压水堆的特点和运行经验,筛选给出可能引起严重事故的始发事件清单,然后基于SCDAP/RELAP5程序建立了反应堆严重事故分析平台,模拟确认了反应堆严重事故的响应序列。以反应堆全部电源丧失事故为例,根据稳压器安全阀响应情况将事故细分为两类断电事故,并分别分析了反应堆系统的热工水力响应行为及特征参数与后果,为评估装置薄弱环节、严重事故管理导则的开发奠定了基础。
According to the character of minitype PWR as well as the operating experience,the list of the initial events result in core damage is screened.After that,the minitype PWR severe accident analysis platform is established based on SCDAP/RELAP5 code,and simulated and validated the reactor severe accidents response sequence.Taking electric power supply blackout as an example and based on the Pressurizer safety valve response,this kind of accident can be divided into two categories.The thermal and hydraulic response and the key parameter and consequence was respectively analyzed,which can give support to the vulnerability assessment and develop the severe accident management guidelines of minitype PWR.
