OFF-PEAK WATER DISPERSAL BASED ON STEAM SELECTING OF NPP ENERGY BLOCKS WITH PWR

Abstract

The article considers the combination of a nuclear power plant (NPP) with water-cooled water reactors (WCWR) and a distillation desalination plant (DDP) with a horizontal-tube film evaporator (HTFE), their joint operation during periods of covering the dips of electric load schedules and thermo-economic efficiency. A number of advantages are presented in comparison with other methods of desalination, technical characteristics and cost of the DDP with a HTFE of made in Russia series, taking into account the costs not included (construction works, work on sea water supply, electric power, brine distillate, distillate). Such an energy complex makes it possible to increase the capacity factor of a nuclear reactor, as well as to solve the problem of lack of fresh water. The thermo-economic efficiency of this energy complex can be determined both by the complete and simplified algorithm by introducing the "thermo-economic index". Wherein the multi-product energy complex with steam supply from the turbine of the nuclear power plant to the DDP with HTFE should be compared with the version of work from special steam boiler plants (SBP). When analyzing the results of calculations using a simplified algorithm based on the thermo-economic index, the effect of the distillate cost factor on the market is noticeable, as well as the less efficient operation of the desalination plant fed with steam from the SBP as opposed to the steam extraction from the nuclear power plant, especially with increasing the number of hours of operation of the DDP of the HTFE.
