摘要/Abstract

摘要： 本文针对海南小堆的实际厂址环境特征,根据机组初步的二级PSA源项,利用更实际的CALPUFF烟团模式开展事故条件下小堆和大堆对场外公众的辐射影响分析,比较不同事故下对周边居民和工作人员的受照特征。按照针对小堆的剂量准则,确定各种天气条件下满足该准则的距离,有助于更深入地认识小堆的事故特征及应急计划区划分等问题,为相关工程实践和应急监管工作提供参考。

关键词: ACP100, 辐射影响, 二级PSA源项, CALPUFF

Abstract: Based on the actual site environmental characteristics of the small reactor in Hainan, this paper uses the more realistic puff model CALPUFF to analyze the radiation effects of the small reactor and the large reactor on the public outside the site according to the preliminary level-2 PSA source term, and the exposure characteristics of different accidents to the surrounding residents and workers are compared. According to the dose acceptance criteria for small reactors, the determination of the distances which meet the criteria under various weather conditions will help to get a deeper understanding of the accident characteristics of small reactors and the division of emergency planning zones, and provide references for related engineering practices and emergency supervision work.

Key words: ACP100, radiation effects, level-2 PSA source term, CALPUFF
