Summary: | A principle schema of an energy complex, including a two-circuit nuclear power plant, a heat phase transition accumulator and an additional steam turbine was developed and investigated. In the course of the work, well-known systems containing phase transition accumulators were analyzed. The known devices are designed only for heating hot water and can not be used to generate steam. To ensure the operation of the heat accumulation system under the required conditions, the design of a heat accumulator with a phase-transition material has been developed. The technical result of the development is to ensure the constructive capability of phase transition accumulators to operate in the steam generation mode. Investigations have shown that the development of heat accumulation systems at nuclear power plants will make it possible for NPP to perform the requirements of System operator of Unified Energy System of Russia about involved in primary control of current frequency, without reduce in the coefficient of the reactor power utilization. This will help to increase the efficiency of energy generating capacities structure, with the possibility of increasing the share of powerful nuclear power units in power systems, and to increase the competitiveness of nuclear power plants in the electricity market. |
