The project is implemented within the KNPP Units 5&6 Modernization Program.
Since the existing radiation monitoring system was obsolete and worn-out, in the frames of unit modernization, the Central Information Measurement Radiation Monitoring System (CIMRMS) of KNPP Units 5&6 and Auxiliary Building 3 was replaced.
The system refers to NPP normal operation safety related systems (class 3Н according to OPB-88/97).
The system is designed for continuous monitoring of KNPP Units 5&6 and AB-3 under normal, emergency conditions (the system maintains its operability under design basis accident conditions, with the exception of Large Break and Unit Loss of On-site Power Supply accident) and under post-accident conditions:
- Radiation situation in the NPP compartments;
- protection barrier conditions;
- Condition and efficiency of the process equipment operation;
- Signal processing system for exceeding the measuring parameters specified levels.
The system provides real time information. The new equipment extends the units lifetime.
