中国实验快堆气载放射性物质释放路径研究

Study on release path of airborne radioactive substances in the China Experimental Fast Reactor

中国实验快堆是我国建设的第一座钠冷快中子反应堆,2014年实现满功率运行。本文主要阐述中国实验快堆气载放射性物质的来源、堆内迁移以及向环境释放的路径,得出正常工况以及事故工况下放射性物质通过哪些路径向环境排放,目的是有助于了解中国实验快堆通过哪些路径对环境产生放射性影响,从而建立并保持对放射性危害的有效防御,以保护人员、社会和环境免受危害,防止工作人员和公众接受超剂量的放射性照射。

The China Experimental Fast Reactor（ CEFR） is the first sodium cold fast neutron reactor in China,which has achieved full-power operation. The source,migration in the reactor core and release pathways of the airborne radioactive materials in the experimental fast reactor of China were analyzed. The pathways discharged to the environment in normal and accident conditions were identified in order to assess the radioactive effects of the CEFR on the environment,and to establish and maintain the protection against radioactive hazards.
