摘　　要：本文给出了5MW 低功率堆厂房屏蔽的设计准则和设计要求,给出了正常和事故工况的源项和相应的辐射剂量场,给出了单晶硅吊运的辐射剂量场,论证了事故工况下主控室的可停留性,发现原设计中主回路设备间和堆厅的屏蔽能力不足,通过恰当的辐射分区和严格的管理措施可以保证工作人员和附近居民的辐射剂量安全。In this paper,the design criteria and design requirements ofthe building shielding in 5MW Low Power Reactor are described.The source term and radiation dose distribution during normaloperation or accident conditions are presented.The radiation dosefield of monocrystalline silicon hanging is given.The residenttime of the main Control room under the accident conditions isdiscussed.In addition,the paper corrects the primary design inwhich the shielding ability of main loop equipment room and re-actor hall are insufficient,by using dose classification and zonerestriction to ensure the radiation dose safety of operating per-sonnel and inhabitant around the plant.
