Description
LAD-07 Liquid Activity Detector is designed to measure the 88Kr radionuclide in the coolant of the primary circuit of a nuclear reactor, which is released into the coolant only in case of fuel cell leaks.
The detector consists of:
– GD-52 based on 2.5 “x 2.5” NaI(Tl) gamma detector (correct probe functionality can be checked by built-in test LED),
– Sandwich shielding GD-52 (lead, tin, copper) near the pipeline with the measured liquid,
– Stainless steel cooler GD-52, through which the coolant flows (ensuring that the maximum working temperature of the detector is not exceeded),
– RPU-12 Data Acquisition and Processing Units with 1024 Channel Analyzer (MCA) to evaluate data from the detector.
Key Features
– Monitoring of fuel integrity through Kr-88 detection in the primary circuit of a nuclear reactor
– Attached to line (ATL) monitor
– Detector shielding reducing the response to increased background
– Water cooled monitor
– Checking of the detector function by means of LED check source (without using radioactive source)
