摘要: 目前我国还没有制定核电厂严重事故后公众辐射风险的可接受性准则。本文提出了一种核电厂辐射风险评价方法,并结合我国徐大堡核电厂的厂址气象条件和人口数据,依据相应机型的二级PSA分析报告,使用MACCS程序对严重事故后公众辐射风险进行分析,并与美国、英国的风险评价准则进行比较,对我国风险可接受性准则的制定有一定参考意义。

Abstract: Acceptability criterion hasn't been made in China for assessment of public radiological risk incurred as a consequence of severe accidents. A methodology related to public radiological risk evaluation for NPP is presented in this paper. Besides, based on the site meteorological condition and population distribution, and the related Level 2 PSA reports, an accident consequence code system (MACCS) is used to calculate the exposure dose and risk after severe accidents for Xudapu NPP. Moreover, comparisons have been made with acceptability criterion in the USA and UK, which may serve as support for making acceptability criterion in China.

Key words: nuclear power plant(NPP), emergency, PSA, risk evaluation
