Abstract

Recent concept designs of supercritical water-cooled reactors (SCWR), which are developed both in the Russian Federation and abroad are presented in the paper. The analysis of the developed projects of reactors with supercritical coolant parameters showed that in most foreign countries, reactors with a thermal neutron spectrum are being designed to solve the immediate problem – replacing light-water reactors. The big majority of SCWR concept designs have one circulation circuit. This is due to the fact that the single-circuit scheme of nuclear power plant (NPP) allows abandoning steam generators and all equipment of the secondary-circuit, reducing the specific quantity of metal by ~40–60%. It also becomes possible to applying of the mastered serial equipment of the turbine island – turbines and heaters, widely used in the thermal power industry in the present. The volume of the containment is significantly reduced and, in general, the capital costs of creating a power unit are reduced by ~20–30%, compared to existing NPPs.
