The results of calculations and experiments proving the possibility of creating in-core monitoring system (IMS) of a pressurized water-water power reactor on the basis of the measurement of the gamma radiation intensity from the reactor core with an original calorimetric gamma detector with a built-in calibration element are pre-sented.
Background and problem statement
In the early 80s, the Nuclear Research Institute of the Academy of Sciences of Ukraine began de-velopment of an IMS system for the 2nd unit of the Armenian NPP. Initially, the unconventional principle of energy release control — by monitoring the field of gamma radiation of the reactor core — was taken as the basis of the physical ideology of the IMS system. Therefore, the system was designated experimental and named EIMS "Sevan".

There were the following backgrounds to put such a task:
