某核电站除盐水处理系统调试

Commissioning of a Demineralized Water System in a Nuclear Power Plant

核电站调试较常规电厂有着明显区别,简要介绍了某核电站除盐水处理系统工艺流程、调试过程,详细描述了调试过程中出现的问题,如SDI不合格、产生虹吸现象、管道位置不合理等,提出了包括确定细砂规格、增加背压阀、改变阀门位置及优化设计等解决方案,验证了方案的可行性,可为同类系统提供参考。

The commissioning of a demineralized water system in a nuclear power plant is marked- ly different from that in the conventional power plant. The technological process and commissioning process of the demineralized water system in a nuclear power plant were briefly introduced. The problems in the commissioning process were described in detail, including unqualified silt density index, siphon- age, and the controversial pipeline positions. The proposed solutions, including specified fine sand size, adding back pressure valves, valve position adjustment and design optimization, were validated and can be used as a reference for similar system. .
