为了分析A P1000核电厂各种潜在的严重事故对周围公众的影响，采用M ACCS程序模拟释入大气中气载放射性物质的弥散过程，对6种代表性释放类别进行剂量风险定量化分析。计算结果表明，事故后24 h内厂址边界附近公众的急性红骨髓剂量风险为1.96×10-7 Sv/（堆·年），该风险大部分来自安全壳旁通释放（BP）；早期健康效应风险在10-10～10-9 Sv/（堆·年），且随着与反应堆距离的增大降幅明显；集体全身有效剂量风险为6.94×10-4人· Sv/（堆·年），引发的癌症致死风险非常低。研究结果还表明，核事故后及时撤离将显著降低公众剂量风险。

In order to estimate the potential offsite effect caused by severe accidents of AP1000 nuclear power plant ,radiation dose risk was quantified ,which takes into ac-count six representative release categories .Atmospheric transport with airborne radio-active material was simulated by MACCS code .The results show that acute red marrow dose risk at the site boundary is 1.96 × 10-7 Sv/(reactor · year) ,which mainly results from containment bypass release (BP) .The early health effect risks are 10-10-10-9 Sv/(reactor · year) ,and the risks decrease obviously with the increase of distance from reac-tor .Population w hole-body effective dose risk is 6.94 × 10-4 person · Sv/(reactor · year) ,and the corresponding cancer fatality risk is quite low .The study result also indi-cates that timely evacuation after the nuclear accident can reduce public dose risk significantly .
