摘要

根据已有的日本福岛第一核电站相关资料,利用美国核管理委员会《轻水堆核电厂事故源项》中的假设条件,计算出事故后安全壳内的放射性源项,综合考虑各种不确定性因素,得出较为保守的环境释放源项。采用美国核管理委员会RG 1.4中大气扩散模式的假设计算大气弥散因子,并应用ICRP 71号出版物F、GR 12号报告等资料中的剂量计算模式及剂量转换因子进行了事故剂量后果的估算、分析和评价。
Conservative source term of radioactive release to the environment is calculated after the accident at Fukushima Daiichi nuclear power station based on updated informational materials and the assumptions made in NUREG-1465 by U.S.Nuclear Regulatory Commission(U.S.NRC),with the consideration of the various uncertainties.And a series of atmospheric dispersion factors are obtained from U.S.NRC Regulatory Guide 1.4(RG 1.4).Finally,this paper provides calculation of the accidental dose,which is analyzed and assessed specifically,using the models and parameters in ICRP Publication 71,FGR 12 and so on.
