THE EXPERIMENTATION ON CONTINUOUSLY MONITORING OF TRITUM OXIDE FROM A STACK OF THE EXPERIMENTAL HEAVY WATER REACTOR

This paper describes some experiments? on the monitoring of tritium oxide inthe effluents of the HWR's stack. The experimental data showed that the equipment can detect 4×10~3 Bq·m~(-3)HTO in air with the presence of argon-41 which has a concentration of about 1×10~5 Bq·m~(-3). The counting rates caused by HTO and ~(41)Ar in the detector aremeasured separatly. The differences of the HTO concentrations in air under thetwo circumstances of the "on operation" and "shut down" of the HWR are com-pared each other. In addition, the advantages and disadvantages of the equipmentare discussed briefly.
