Simulation of accidental temperature and humidity in the pipeline rooms of the VVER NPP primary circuit

Abstract

The paper considers temperature and humidity simulation of the primary circuit pipeline rooms located at power units No. 3 and 4 of the Kola NPP upon the occurrence of equipment leakage. Simulation results were used to describe the dependence of the leakage on the temperature and relative humidity recorded by the sensors. Thus, advanced methods of automated coolant leak detection were developed; existing methods were adjusted.
