摘要/Abstract

摘要： 简要分析了M310/CPR1000、EPR和AP1000三种堆型正常运行裂变产物源项计算中存在的问题,结合法规标准的要求,以及近年国内核电厂的运行实践、源项审评和研究成果,从源项应用目的出发,研究提出了一套适用于我国压水堆核电厂裂变产物源项计算的框架。该框架理顺了核电厂裂变产物源项的计算流程,规范了不同堆型核电厂裂变产物源项的计算方法,为解决国内核电厂裂变产物源项计算中长期存在的问题提供了基础,可供核电厂源项计算时参考。

关键词: I-131当量, 裂变产物源项, 一回路源项, 排放源项

Abstract: The problems existing in the fission product source terms calculation for M310/CPR1000, EPR and AP1000 NPPs under normal operation are briefly analyzed. Based studies on the related regulations and standards, as well as operational feedback, review experiences and recent research achievements, a framework of fission product source terms estimation applicable for the PWRs in China was proposed. The proposed framework streamlines the calculation processes of fission product source term and has the requirements for deferent reactor types specified. The proposed framework can be taken as the foundation for solving the long-standing problems in the calculation of fission product source term and provide reference in source term calculation.

Key words: dose equivalent I-131, fission product, primary coolant source term, release source term
