Abstract: | Trends in the development of the power sector of the Russian and world power industries both at present time and in the near
future are analyzed. Trends in the rise of prices for reserves of fossil and nuclear fuels used for electricity production
are compared. An analysis of the competitiveness of electricity production at nuclear power plants as compared to the competitiveness
of electricity produced at coal-fired and natural-gas-fired thermal power plants is performed. The efficiency of the open
nuclear fuel cycle and various versions of the closed nuclear fuel cycle is discussed. The requirements on light-water reactors
under the scenario of dynamic development of the nuclear power industry in Russia are determined. Results of analyzing the
efficiency of fuel utilization for various versions of vessel-type light-water reactors with supercritical coolant are given.
Advantages and problems of reactors with supercritical-pressure water are listed. |
