移动式氢复合器在福清核电站的应用

Application of Mobile Hydrogen Recombiner in Fuqing Nuclear Power Plant

移动式氢复合器是在反应堆发生设计基准事故时,使氢气和氧气复合成水,有效地控制安全壳内的氢气浓度在安全浓度范围以内,以确保维持安全壳结构和密封性的完整性。文中介绍了移动式氢复合器在福清核电站的应用,分析了移动式氢复合器的反应原理、在设计基准事故时的消氢能力和在役检查,说明了福清核电移动式氢复合器具备对安全壳内氢气去除的能力,可大大降低氢气爆炸对安全壳的威胁。

When the reactor occurs design basis accident,a mobile hydrogen recombiner can make the hydrogen and oxygen combined into water,thus control the hydrogen concentration in the containment within safe levels effectively to ensure the sealability and integrity of containment structure.This paper introduces the application of mobile hydrogen recombiner in Fuqing nuclear power plant,and analyze the reaction principle,in-service inspection, and it＇s hydrogen-eliminating efficiency of mobile hydrogen recombiner.The analysis result show that mobile hydrogen recombiner in Fuqing nuclear power plant have the capability of eliminating the Hydrogen within containment,it can greatly reduce the threat of hydrogen explosion on the containment.
