压水堆核电厂消氢装置选用探讨

Discussion of Nuclear Hydrogen Ignition Equipment Selection

为消除核电厂在严重事故工况下积聚在安全壳内的氢气,需要在核电厂安全壳内增加消氢装置。本文分析了严重事故工况下目前主要采用的氢气点火器和非能动氢复合器的原理,并结合某核电厂增加非能动氢复合器改造的工程实践,给出了压水堆核电厂消氢装置选用方案。实践结果表明,此最优消氢方案既可以保证电厂安全,又可以节约成本,具有巨大的社会效益和经济效益。

In order to eliminate concentration hydrogen in the containment under the severe accidents of nuclear power plants, it is necessary to add Hydrogen Ignition Equipment. The paper analyzes the main theory of the hydrogen igniter and passive autocatalytic recombiner which are used mostly, and how to select the nuclear hydrogen ignition equipment, based on the improvement of adding the nuclear hydrogen recombiner of a nuclear plant. The improvement of the nuclear plant shows that it is very important to select the most suitable hydrogen ignition equipment for nuclear plants and society.
