Some safety relevant concerns,such as the fuel temperature and primary loop pressure,the graphite corrosion mass,the explosive gas releasing amount,as well as the natural convection influence under the condition of the failure of the blower baffle shut down,were studied.

计算结果表明:在蒸汽发生器1根传热管双端断裂、最大进水量600 kg情况下,事故后燃料元件的最高温度远低于设计限值,化学反应所引起的石墨腐蚀不会造成反应堆结构强度的破坏和燃料元件的意外破损,释放到反应堆舱室的可燃气体含量也不存在爆炸危险。
