Preliminary Design of Hydrogen Decreasing System in Large Dry Containment
-
摘要: 以岭澳核电站为分析对象,利用MELCOR和TONUS (CEA)程序进行分析计算,给出了初步的消氢系统设计方案,对不同核电站的消氢系统设计方案进行了对比和讨论。结果表明:安全壳内安装33个FR750型或者17个左右的FR1500型氢气复合器可以满足氢气控制要求。

Abstract: In severe accident of PWR,large amount of hydrogen may accumulate in the containment,combustion or detonation may occur and challenge the integrity of containment.Passive autocatalystic recombiners (PARs) should be installed to mitigate the hydrogen risk.Aiming at Lingao phase 2 nuclear power plant,using MELCOR and TONUS,a preliminary design of hydrogen mitigation system has been given.Different hydrogen mitigation systems are also compared in this paper. -
