摘要
核电站严重事故下，氢气释放到安全壳内，可能发生氢燃或氢爆，对安全壳的完整性和设备可用性构成威胁。本文评述了氢气的来源和氢气控制措施，阐明了第三代压水堆AP1000采取非能动催化氢复合器结合冗余多样点火器的方式可以安全、有效地降低氢气燃烧和爆炸对安全壳带来的风险，并与国内核电站氢气控制的不同设计进行了比较。
Under severe accident conditions of the nuclear power station, Hydrogen is released inside containment, the integrity of containment and component availability is threaten by hydrogen combustion or detonation. The paper states the hydrogen source and control measures, explains design features about hydrogen control for the third generation of AP1000 PWR. The recombination of passive autocatalytic recombiners arid redundant igniters is a safe, effective way to reduce the hydrogen combustion risk. Finally, it compared with hydrogen control design of domestic plants.
