摘要/Abstract

摘要： 为评估EPR机组功率运行和停堆期间反应堆厂房的空气污染水平,本文介绍了空气污染评估方法,并建立了H-3的空气浓度估算模型;估算了功率运行期间和停堆期间反应堆厂房设备间和工作间的空气污染水平。评估结果显示,在停堆期间,反应堆厂房空气污染的主要核素是H-3,大约为0.07 DAC,其导致的大修集体剂量可以达到56人·mSv。

关键词: EPR, 空气污染, H-3

Abstract: The method for estimating the air contamination conditions in EPR reactor building during power operation and shutdown is described, and a model for estimation of the H-3 activity concentration is established. Air contamination levels in the equipment room and the work room of reactor building during the power operation and shutdown are evaluated. The results show that H-3 is the main contributor for air contamination in reactor building during the shutdown with a concentration in air of about 0.07 DAC, which could cause a collective dose of about 56 man·mSv in a typical outage

Key words: EPR, air contamination, H-3
