核电站去污工艺在清洁解控中应用的探讨

Discussion of Cleaning Technology on the Application of Clearance in Nuclear Power Plant

根据国内核设施放射性废物最小化的要求,清洁解控作为减小放射性废物产生量的重要运行管理措施之一,被不断的完善和逐步应用。本文针对清洁解控过程中,放射性固体废物污染水平存在超过直接清洁解控水平要求的情况,提出可采用核电站常用的去污方式降低放射性水平,并针对部分的去污工艺开展了工艺系统的初步设计,为核电站运行期间以及退役过程的放射性废物处理提供一定的参考价值。

According to the requirements for minimizing radioactive waste in nuclear power plant,as one of the important operational management measures to reduce the production of radioactive waste,clearance has been continuously improved and applied.In response to the radiation level of radioactive solid waste exceeds the level of clearance level,the cleaning technology in nuclear power plant is proposed to reduce radiation level in clearance.Preliminary design has been carried out for some cleaning technology.It provides certain reference for the treatment of radioactive waste during the operation and decommissioning process of nuclear power plant.
