水生生物辐射影响评价软件ERICA版本变化分析及工程应用

Analysis and Engineering Application of Differences of Aquatic Organisms Radiological Impact Software ERICA Code Version

摘要: 介绍了水生生物辐射影响评价软件ERICA程序的计算原理及评价准则，分析了程序新版本ERICA1.2与上一版本ERICA1.0相比的主要变化，并以我国某压水堆核电厂厂址为例，分别采用程序ERICA 1.0版和1.2版分析该电厂正常运行工况下液态流出物排放对厂址附近水生生物的辐射影响。结果表明，使用程序的两个版本计算该电厂两台机组正常运行时的液态流出物对厂址附近水生生物的影响都是可接受的，厂址附近水生生物是安全的。

Abstract: The calculation principle and evaluation standard of the aquatic organisms' radiological impact software-ERICA code were introduced in this paper, and the differences of 1.0 version and 1.2 version were compared. The radiological impact of aquatic organisms when the nuclear power plant operates normally was calculated and evaluated through ERICA code 1.2 version and 1.0 version separately.The result shows that the radiation effects on aquatic organisms when the nuclear power plant operates normally calculated and evaluated through ERICA code 1.2 version and 1.0 version are all acceptable, the aquatic organisms nearby site are safety.
