| Abstract: | The recirculating pit filter in containment is an important equipment of safety system in nuclear power plant.In the recirculating condition,it influences the operation of emergency reactor core cooling system and spray system in containment.Static analysis under dead weight and nozzle loads,modal analysis,and spectrum analysis under seismic loads were performed.The results demonstrate that the stress combination and evaluation under each service level satisfy the requirement of ASME codes.The effect of structure's parameters on its earthquake-resistant performance was displayed. |
