CANDU6重水堆装卸料机内乏燃料失去冷却事件过程与分析

Event Process and Analysis of Loss of Cooling for Spent Fuel Bundle inside Fuelling Machine at CANDU6 PHWR

本文对装卸料机丧失循环冷却流量导致乏燃料失去冷却并释放裂变产物的过程进行了事件分析，给出了乏燃料破损给反应堆厂房和外界环境带来的后果，探讨了乏燃料失去冷却时的应对措施。

This artcle analyzed the event of loss of cooling for spent fuel bundle and fission product releasing due to loss of forced circulation cooling flow in fuelling machine. The article presented the results of effect due to the fuel bundle rupturing to reactor building and environment. Also,it discussed the countermeasure to deal with the event of loss of cooling of spent fuel bundle.
