Study of electrical energy coupling between turbine and compressor in gas-cooled small modular reactor

The system of electrical transfer of energy between the turbo-system in the secondary circuit and main circulating compressor in the primary circuit of a small modular nuclear reactor has been proposed and simulated with regard to the energy balance and reliability to ensure the proper functioning in standard operation and also during run-down of this gas-cooled reactor. A simplified model has been also compiled to make identification of basic dynamic and power properties of this complicated system very quick even in longer time scales.
