WWER机型一回路冷却剂裂变产物设计源项与现实源项的探究

Analysis of Design & Realistic Source Terms of Primary Coolant for the WWER-type NPP

一回路冷却剂源项是核电厂核与辐射安全的重要基础数据。本文采用RELWWER程序,并结合核电厂的实测数据,对WWER1000型机组一回路冷却剂裂变产物源项进行了分析及计算考虑一定的设计裕度,得到了一套设计源项和现实源项,可为该机型辐射防护和放射性废物管理的设计提供参考。

The source terms of the primary coolant of NPP is one of the basics data for radioaction safety and radioactive waste management.This article analyses the source terms of the primary coolant for WWER1000 type units.The source terms is calculated by RELWWER program,considering measurement data and conservation.The calculation result may help for the designing of design and realistic source terms of primary coolant of WWER1000 type NPP.
