AP1000核电厂事故情况下安全壳的氢气控制

Control of Hydrogen Inside of Containment With Accident Based On AP1000 Plant

本文介绍了事故后安全壳内氢气产生的原因,以及氢气在安全壳内燃烧引起的危害。分析了AP1000安全壳氢气控制系统的设计特点,以及该系统如何在设计基准事故和严重事故下控制氢气浓度,并与传统二代核电厂的安全壳消氢系统进行对比,分析了AP1000在氢气控制方面的优越性,并对该系统设备的运行提出了建议,可以做为国内新建电厂的设计借鉴。

This paper gives a introduction of the reason of hydrogen produced in containment, and the harm of hydrogen burning, and analysis the design feature of containment hydrogen control system and the system how to control hydrogen concentration following a DBA and a severe accident, compares it to traditional second generation nuclear power plant ,analysis the superiority of AP1000 containment hydrogen control system, gives some advice of the operation of equipments ,can be an example of new nuclear power plant design.
