摘要
“华龙一号”(Hualong pressurized reactor 1000,HPR1000)设置了多种严重事故预防与缓解措施,有必要对氢气风险控制相关的缓解措施与其他缓解措施综合作用下的氢气风险进行研究。利用严重事故一体化软件建立了“华龙一号”电厂模型,结合严重事故后安全壳内氢气可燃性判断准则,研究了典型事故后非能动安全壳热量导出系统(passive containment heat removal system,PCS)作用下的安全壳内氢气浓度分布,分析了PCS对严重事故后氢气风险的影响。研究结果可为“华龙一号”严重事故管理措施的有效性论证提供支持。
Various severe accident prevention and mitigation measures are set in Hualong pressurized reactor 1000(HPR1000).It’s necessary to make research on hydrogen risk influenced by the general effect of mitigation measures for hydrogen risk control and others.The HPR1000 PWR model was built by integral severe accident analysis code.By combination with the hydrogen combustion criteria in containment after severe accident,the hydrogen concentration distribution in containment impacted by passive containment heat removal system(PCS)after a typical accident was researched,which could support the effectiveness of severe accident management measures of HPR1000.
