摘要

核电厂一回路的异物随着冷却剂进入到堆芯被活化，活化后的异物具有很高的放射性，而这些高放射性的异物往往容易沉积在一回路相关设备内。针对一回路异物打捞工作容易造成工作人员受到超剂量照射的问题，设计了专用转运屏蔽装置、高放废物贮存容器、转运区域隔离管控要求，可以有效降低异物转运和贮存时对周围区域辐射水平的影响，确保工作人员的辐射安全。经验证，异物活化的理论计算结果与现场实测辐射水平基本一致，理论计算结果可为异物打捞工作的辐射防护工作方案、人员防护措施制定提供理论指导。

Abstract

The foreign materials in primary of nuclear power plant are activated with the coolant into the core, and the activated foreign materials are highly radioactive, while these highly radioactive foreign materials are often easily deposited in the primary related equipment. Hence, operators are frequently overexposed to radiation during foreign body salvage work in primary systems. Special transfer shielding devices, high discharge waste storage containers, and transfer area isolation control are designed to effectively reduce the impact of foreign body transfer and storage on the radiation level of the surrounding area and to ensure the radiation safety of the staff. Theoretical calculations of foreign body activation are consistent with the measured on-site radiation levels and can be used to guide the radiation protection work plan and personnel protection measures during foreign body salvage work.
