凝结水精处理系统在机组大修期间需要进行隔离检修。由于凝结水精处理系统包含四个部分:阳床、阴床、再生床、水箱;由树脂床和相应管线、阀门组成,在大修期间除了给工作负责人一个安全的检修环境外,也需要对备用状态的树脂进行保护,为了达到这两个目的,大修期间凝结水精处理系统的主隔离进行了特殊的设置和准备。本文针对国内某核电站在多次大修中,凝结水精处理系统主隔离的准备和优化进行表述,希望有助于此问题的处理。
Condensate polishing system needs overhaul during unit overhaul. As the condensate polishing system consists of four parts: the positive bed, the negative bed, the regeneration bed, the water tank; by the resin bed and the corresponding pipeline, the valve composition, during the overhaul in addition to the responsible person responsible for a safe maintenance environment, but also to The resin in the standby state is protected. For these two purposes, the main separation of the condensate polishing system during the overhaul has been specially set up and prepared. In this paper, a nuclear power plant in China in a number of overhaul, condensate polishing system main isolation preparation and optimization of the presentation, hoping to help deal with this problem.
