Validation of the steam generator model in the RASNAR-GAZ software for calculating the dynamics of a gas-cooled reactor plant

Abstract

The present paper considers the RASNAR-GAZ validation of the computational model for the steam generator. The model is designed to calculate non-stationary modes of gas-cooled nuclear power plants. For this purpose, experimental data of the THTR-300 reactor were used. The performed validation proved the RASNAR-GAZ software to describe the main parameters of heat and mass transfer between helium and water in a steam generator with accuracy sufficient for engineering calculations of both static and dynamic modes.
