Improving the efficiency of a BREST-300 NPP using the thermal energy of natural gas

Abstract

A schematic thermal diagram of a turbine plant with a thermal gas boiler developed for nuclear power plants with BREST-300 reactors, which considers means for ensuring increasing power generation efficiency at power facilities, is presented. The heat produced in a gas boiler during the combustion of organic fuel is used for an initial and intermediate superheating of the working fluid upstream the turbine cylinders, as well as for preheating the air supplied to the boiler. The BREST-300 NPP discussed in the work is designated as an organic-nuclear power plant (ONPP). In the presented version of the thermal diagram for a turbine plant, the internal efficiency of the cycle is 54.12%.
