摘要/Abstract

摘要： 介绍了美国核审管部门对核动力厂选址假想事故源项确定的历史演变以及相关研究进展。推荐了一套核动力厂选址假想事故源项,以及确定非居住区边界的评价分析方法和假设条件。计算了M310和AP1000核动力厂厂址的非居住区的最大径向距离。计算结果表明:(1)对于M310和AP1000核动力厂,采用确定论方法估算大气扩散因子,安全壳泄漏率(体积分数)取0.3%/d,非居住区最大径向距离分别不超过1.4 km和1.9 km;(2)在厂址选址阶段,考虑核动力厂的技术路线尚未明确或采用新技术路线,采用“不考虑安全壳喷淋系统等能动安全设施对核素的去除作用”的选址假想事故源项来确定厂址非居住区的边界基本上是可行的。

Abstract: The evolutionary history and researching progress of nuclear power plant postulated siting accident of the U.S. nuclear regulatory authority is introduced. A set of assumptions of postulated siting accident is recommended for determining the exclusion area boundary (EAB) of nuclear power plant.The calculated maximum radius of the exclusion area about the M310 and AP1000 nuclear power plant is provided. The results indicate that: (1) The maximum distance of EAB is no more than 1.4 km and 1.9 km; (2) During siting phase, application of the postulated siting accident to determine the boundary of nuclear power plant, without considering the removal capability of active engineered safety feature, is practicable.

Key words: nuclear power plant, postulated siting accident, exclusion area
