A study on the influence of passive containment heat removal system of HPR1000 on hydrogen risk
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.
