CENTRAL INFORMATION MEASUREMENT RADIATION MONITORING SYSTEM (CIMRMS-01P) OF KOZLODUY NPP UNITS 5&6 AND AUXILIARY BUILDING 3

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.
