本文详细介绍了重水堆运行时~(41)Ar 的来源和其排放率的研究结果。为监督排出~(41)Ar 对环境的影响,反应堆厂房内设有监测系统,以测量烟囱和工艺房间空气中的放射性气体。从烟囱取出的空气样可连续通过用~(41)Ar 进行标定的电离室。最后指出了降低~(41)Ar 排放量的途径。
This paper describes in detail the source of ~ (41) Ar and its emission rate during heavy water reactor operation. In order to monitor the environmental impact of the discharge of (41) Ar, a monitoring system was installed in the reactor building to measure the radioactive gases in the air of the chimney and craft room. The air sample taken from the chimney can pass continuously through the ionization chamber calibrated with ~ (41) Ar. Finally, the ways to reduce the emission of ~ (41) Ar are pointed out.
