摘要: 研究了欧洲用户要求(EUR)文件中的概率安全目标,重点研究了核电厂设计扩展工况的有限影响准则。鉴于EUR中没有关于有限影响准则的阈值和环境影响系数的确定方法,尝试研究准则中阈值和系数的计算方法,并采用我国核电厂的相关数据,使用事故剂量模式和均匀释放假设,计算了有限影响准则中的阈值和核素的环境影响系数,最后探讨了有限影响准则与大量放射性释放的关系,以及有限影响准则在我国的适用性。

关键词: EUR, 有限影响准则(CLI), 阈值, 环境影响系数, 干预水平

Abstract: This paper investigates the probabilistic safety targets in European Utility Requirements document and studies the Criteria for Limited Impact, which is applied for the assessment of the acceptability of the design in DECs. Since there are no methods to determinate the criterion and the coefficients of CLI, we try to calculate the criterion and the coefficients of CLI using the accident dose modes, the hypothesis with homogeneous release and data of nuclear power plant in China. It finds that the magnitude of part coefficients is about one order different from that in EUR. Finally, we discuss the relationship between the CLI and large release, and its availability.

Key words: EUR, CLI, threshold, environmental effect coefficients, intervention level
