全厂断电事故工况下，反应堆乏燃料水池冷却和处理系统存在较大的停运风险。为避免反应堆乏燃料水池失去冷却事故工况的进一步恶化，使用ORIGEN‐S程序计算了不同状态下从乏燃料水池失去冷却到乏燃料组件裸露的最短时间。结果表明，在最恶劣工况下，乏燃料组件裸露的最短时间为79.2 h ，该结果也被用于制定秦山第二核电厂的应急响应行动计划。
全廠斷電事故工況下，反應堆乏燃料水池冷卻和處理繫統存在較大的停運風險。為避免反應堆乏燃料水池失去冷卻事故工況的進一步噁化，使用ORIGEN‐S程序計算瞭不同狀態下從乏燃料水池失去冷卻到乏燃料組件裸露的最短時間。結果錶明，在最噁劣工況下，乏燃料組件裸露的最短時間為79.2 h ，該結果也被用于製定秦山第二覈電廠的應急響應行動計劃。

In the case of station blackout accident ,the reactor spent fuel pool cooling system had a high risk to break down .In order to avoid the accident without the reactor spent fuel pool cooling going worse ,the minimum time from the spent fuel pool lost cooling to the spent fuel assembly exposing was calculated by using the ORIGEN‐S code .The calculation results show that the minimum time of the worst case is 79.2 h , and the results are also used to establish the emergency response plan for Qinshan NPP‐2 .
