The project of PIK reactor (Petersburg Nuclear Physics Institute named by B.P. Konstantinov of National Research Center «Kurchatov Institute») assumes existence of continuous remote control of heavy water moderator coolant. For this purpose, an automatic flow analysis system of heavy water (AFAS HW) has been developed. An on-line water radiation monitor (flow-through radiometer) was included in this system for tritium activity measurement.
In this article, the test results of on-line water radiation monitor called Wilma are presented. The basic metrological characteristics of the device have been established. Comparative measurements were made by using heavy water control samples. Calibration of the instrument was carried out. The efficiency of tritium measurement and the stability of the work have defined. Obtained results show the applicability of Wilma to the tritium continuous remote control.
