摘要:参考NUREG-0396中烟羽应急计划区划分方法与接受准则,基于EPR机组的二级PSA结果中的严重事故释放类,对各堆芯熔化事故释放类采用概率加权,用MACCS程序计算得到某EPR机组烟羽应急计划区的大小,并以截断频率10-"/(堆·年)选取最严重事故序列的释放类(RC205)对结果进行复
核。计算得到某EPR机组烟羽应急计划区内区半径3km、外区半径7km能满足接受准则。关键调:概率安全分析;核电厂;应急计划区;严重事故序列

Abstract: According to China's nuclear power plant regulations and standards, the acceptance criteria based on the NUREG-0396 report is used to the plume emergency plan zoning for EPR unit. The source terms of release categories in the Level-2 PSA of the EPR unit are selected as the referenced source terms, and the individual consequence of each source term and the weighted average of these consequences are calculated and analyzed by using MACCS code, RC205 is selected as "the severest accident sequences" based on the frequency truncation (1o" reactor-year), and the consequence is calculated and analyzed. As a result, 3 km internal zone radius, and 7 km outer zone radius meets the acceptance criteria.
