核电厂常规岛消防灭火系统设计的几点建议

Suggestions on Fire Fighting Design for Conventional Island in Nuclear Power Plants

  • 摘要: 为满足消防灭火系统安全运行、便于维护,对常规岛厂房内消防系统设计中存在的问题提出了几点改进建议。根据消防系统运行维护手册结合现行消防系统设计规范和运行人员反馈,对核电厂常规岛厂房内各消防灭火系统进行梳理。提出了消防水分配系统中疏水阀和排气阀设置建议;提出了常规岛自喷水灭火系统水流指示器和闭式喷头布置注意事项;提出了励磁机灭火系统的设计原则;提出了消防系统阀门布置建议;提出了消防排水系统优化设计建议。改进后的消防灭火系统,便于运行维护,可供核电厂常规岛消防设计人员参考。

     

    Abstract: Some suggestions have been provided on fire fighting design of conventional island in nuclear power plants from the point of view of safe operation and equipment maintenance. Vrious fire fighting sstems in conventional island in nuclear power plants had been sorted out basing on fire fighting system design specification and operational feedback. Setting recommendations on the traps and exhaust valves as well as design principle of exciter fire fighting system have been proposed. Flow indicator and closed nozzle arrangement precautions and fire fighting system valve arrangement recommendations in conventional island in nuclear power plants have also been provided. This work provides some guidance for Fire fighting designers of nuclear power plants.
