三门核电换料水池去污作业辐射防护优化设计

Optimization Design of Decontaminating Refuel Pool for Radiation Protection at Sanmen Nuclear Power Plant

核电站换料水池去污是核电站大修期间的一项工作。本文分析了目前我国核电站换料水池去污作业在辐射防护上的一些不足,提出应用γ相机和无线个人剂量监测系统等新型设备,对水池去污作业进行优化设计。该方案可实时监控水池放射性污染分布和作业人员状态,有效控制人员所受剂量。

Decontamination of refuel pool is a job in the heavy repair of nuclear power plant in order to protect repair men from radiation hurt. The character of pool decontaminating is analyzed and the deficiency for radiation protection is found. The optimization design of decontaminating refuel pool for radiation protection is showed in this paper,which make use of γ- ray image devices,wireless electronic personal dosimeters and other new type devices. The designed system can monitor the radioactivity distribution in the refuel pool and the situation of worker in real time. The radiation dose of worker will be controlled,and the risk of radioactivity contamination will be reduced,and decontaminating efficiency will be increased.
