事故条件下模块化小堆与同厂址大堆的辐射影响对比分析

Abstract

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
