Liquid Activity Detector
The monitor to measure the 88Kr radionuclide in the coolant of the primary circuit of a nuclear reactor.
Nuclear power plants
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)
Description
The 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.
Product design and specifications are subject to change without prior notice or obligation.
