ENERGY-SAVING SEAWATER DESALINATION SYSTEM USING STEAM GENERATED IN NUCLEAR REACTOR, AND METHOD FOR DESALINATING SEAWATER

摘要

The present invention relates to a seawater desalination system which improves energy efficiency by applying seawater desalination to heated cooling water discharged from a nuclear power plant and high-temperature steam generated in a nuclear reactor. A seawater desalination system according to one example of the present invention comprises: a steam supply pipe (40) for supplying heat exchange steam, which is a part of steam exhausted from a turbine (20); a seawater supply pipe (36) which diverges from a discharge pipe (34); and a heat exchanger (50) which is connected to the steam supply pipe (40) to be supplied with the heat exchange steam and is connected to the seawater supply pipe (36) to be supplied with first seawater, which is a part of seawater discharged from a condenser (30), wherein the heat exchanger (50) increases the water temperature of the first seawater by using heat included in the heat exchange steam, and the first seawater is desalinated as the first seawater, of which the water temperature has been increased, is supplied to a fresh water generating unit (2) through a connection pipe (4).
