Structural and Parametric Optimization of S-CO Nuclear Power Plants.

The transition to the use of supercritical carbon dioxide as a working fluid for power generation units will significantly reduce the equipment's overall dimensions while increasing fuel efficiency and environmental safety. Structural and parametric optimization of S-CO nuclear power plants was carried out to ensure the maximum efficiency of electricity production. Based on the results of mathematical modeling, it was found that the transition to a carbon dioxide working fluid for the nuclear power plant with the BREST-OD-300 reactor leads to an increase of efficiency from 39.
