摘　　要：为分析“华龙一号”事故后场外风险,开展了“华龙一号”三级概率安全分析。对“华龙一号”建立了三个阶段的工作流程,选取PC COSYMA作为评价工具,识别了该软件的局限性,建立了基于通用厂址条件的三级概率安全分析方法论,并开展了“华龙一号”的三级概率安全分析。分析得到剂量-频率分布、个人风险以及社会风险,论证了“华龙一号”的事故后场外风险整体处于较低水平。In order to analysis the off-site radiation risks in potential accidents,the Level 3 Probabilistic Safety Assessment of HPPR1000 is performed.The Radiation Protection Targets of HPR1000 were chosen and built up.The PC COSYMA is chosen as the tool of Level 3 PSA of HPR1000.The Level 3 PSA methodology which is based on the generic site is built up and performed to get the public doses,individual risks and societal risk of HPR1000.The overall results of HPR1000 meet Basic Safety Levels of numerical targets.Some of risks are lower than Basic Safety Objectives of numerical targets.These proved the overall level of risk of HPR1000 are low and acceptable.

关 键 词：三级概率安全分析 个人风险 社会风险 合理可行尽量低
