Abstract：
 This invention relates to coupling apparatus and method for desalting seawater by using nuclear energy. The apparatus comprises: a small-scale nuclear thermal reactor, a reverse osmosis seawater desalting system, a distillation seawater desalting system, and auxiliary apparatus. The method comprises: (1) transferring the heat generated from the small-scale nuclear thermal reactor to the steam generator, and driving the reverse osmosis high-pressure pump with the generated saturated steam in the turbine for seawater desalting; (2) introducing the saturated steam exhausted from the end stage of the turbine to the distillation seawater desalting system for seawater desalting; (3) returning the condensed water to the steam generator; (4) introducing seawater into the distillation seawater desalting system, cooling at the heat discharge section, sending to the reverse osmosis high-pressure pump, pressurizing, sending to the reverse osmosis seawater desalting system, storing the product water in a desalted water tank, and utilizing the condensed seawater or discharging into sea. The method has such advantages as advanced technology, high heat utility, high water productivity and high water quality.
