摘要
低浓度硼酸溶液水箱是WWER1000压水堆核电站硼水贮存系统的一个主要设备,用于贮存一回路含硼水。由于其辐射风险较高,水箱的内部检修给辐射防护工作带来了诸多问题。对田湾核电站低浓度硼酸溶液水箱容器检修过程中采取的集体剂量控制和放射性污染控制措施进行了简要的介绍和探讨,主要包括该项检修作业的辐射风险分析及各类辐射风险所采取的防护措施,并对所采取的防护措施进行效果评价。
The low concentrated boric acid storage tank( LC- BAST) is a major equipment of boric solution storage system for WWER1000 PWR. It is used for the storage of the primary-loop boric solution. The maintenance of the tank causes many issues of radiation protection. In this paper,the practice and methods of occupational exposure control in the maintenance of the tank are introduced,mainly including the radiation risk analysis and the practice of radiation protection,and evaluating the protective effect during the maintenance.
