快堆辐射监测系统定期试验方案的改进设计

The Improved Design of RMS Periodic Test Scheme in CEFR

鉴于放射源的使用在辐射监测系统定期试验中带来的辐射安全问题,需要对试验方案进行改进设计。本文通过对探测器输出信号特性及电子学线路对信号处理方法的研究,介绍一种利用电子学方法产生的信号代替探测器的输出信号,实现在无放射源操作的情况下完成定期试验的方法。

High-level radioactivesources were used in the periodic test of the radiation monitoring system （RMS） for China experiment fast reactor （CEFR）, which would bring the radiation safety problems. Therefore, it is needed to improvethe testscheme. In this paper, theoutput signals of the scintillation detector for different radioactive level and the signal processing methodsof the electronic circuit have been analyzed,one scheme using the electronic signal to substitute the detector output is presented for RMS periodic test, which can accomplish the periodic test without radioactive source.
