压水堆核电厂便于退役的沉积源项控制措施研究

Studies on Deposition Source Term Control Initiatives Convenient to Decommissioning of PWR

从源头控制辐射源项的产生,是实现辐射防护最优化和废物最小化目标中最为经济、有效的手段。本文从核电厂设计阶段和运行管理的角度出发,对沉积源项控制措施进行了研究,包括钴源减少技术、材料表面预处理技术、一回路水化学控制技术等,以便为提升核电厂退役阶段的辐射防护水平,降低放射性废物处理成本等提供参考。

Controlling the generation of radioactive source terms from the origin is the most economical and effective method to radiation protection optimization and waste minimization. This article summarized these control initiatives of deposition source terms from the perspective of design and operation management, including cobalt source reduction, material surface pretreatment, water chemistry control, in order to improve the radiation protection level in decommissioning and reduce the costs of waste disposal.
