ηnetto, average mechanical efficiency of the turbines, ηT, the relative steam flux mx/m0 and the relative turbine inlet pressure in function of changes in the power plant load Nx/NG for the “twin” cycle

ηnetto, average mechanical efficiency of HP and LP part of the turbine, ηT, as well as the relative steam flux mx/m0, all in function of change in the power plant load Nx/NG for the cycle with interstage overheat

power plants at the present time.
The analysis of the efficiency characteristics that single-case steam turbines operating under a simple thermodynamic cycle, doubled or multiplied in ship power plant, are able to ensure a higher energy conversion efficiency of power plant at partial loads. The idea of application of high-temperature, graphite-moderated, helium-cooled nuclear reactors eliminates operational disadvantages of contemporary ship nuclear power plants by increasing their parameters over those of contemporary conventional steam power plants.
Application of HTR reactors improves hence profitability of ship nuclear power plants compared to today used PWR reactors, increases their safety and lowers hazards to the environment.
