摘　　要：美国联邦法规10CFR§50.34(f)规定：当100％燃料包壳金属-水反应产生的氢气释放进入安全壳,并且伴随着氢气燃烧时,安全壳必须能维持其完整性。本文在保守地假设氢气在安全壳内等体积、绝热、完全燃烧的基础上,根据热平衡方程和理想气体方程推导出事故后安全壳内氢气燃烧引起的压力负载估算方法,并用此方法分别对国内新设计的300MW和1000MW核电站估算了100％燃料包壳金属-水反应产生的氢气在安全壳内燃烧引起的压力负载。计算结果表明两者的安全壳设计均能满足相关法规要求。As stated in 10CFR §50.34（f）, containment integrity will be maintained during an accident that releases hydrogen generated from 100% fuel clad metal,water reaction accompanied by hydrogen burning. This paper presents the method to calculate the combustion pressure load post accidents assuming the combustion process is adiabatic, complete and at constant volume, based on the energy balance equation and ideal gas equation before and after hydrogen Combustion. Then, based on this method, this paper calculates the pressure loads of 300MWe and 1000MWe Nuclear Power Plants designed in China from hydrogen combustion generated 100% fuel clad metal-water reaction, and demonstrates the containment design of these two types meet the requirements of 10CFR§ 50.34（f）.
