大亚湾核电站安装氢气复合器方案计算分析

Analysis of NIS PARs Installation in Daya Bay Nuclear Power Station

针对大亚湾核电站在严重事故条件下安全壳内氢气的产生、释放以及氢气复合器对氢气浓度的影响进行了研究。在假设安全壳内安装一定数量的NIS型被动催化式氢气复合器的条件下,研究了氢气浓度在安全壳内的变化。结果表明,当安全壳内安装大约50个氢气复合器时,最大氢气浓度可以控制在10%左右。

This paper describes the hydrogen production and release,and the effect of NIS PARs on thehydrogen concentration in the containment in Daya Bay nuclear power station.The variation of hydrogenconcentrations in the containment with the assumed number of NIS PARs inside the containment is studied.The results show that the peak hydrogen concentration could be controlled at about 10% with around 50 NISPARs inside the containment.
