Use of seawater cooling water in nuclear power plants and thermal power plants

摘要

PROBLEM TO BE SOLVED: To perform the production of metallic sodium to generate the alternative energy of fossil fuel by utilizing energy heat-stored in waste seawater while maintaining cooling effect, in order to solve the following problem that: for obtaining the electric power of one million kW in one nuclear power plant, the amount of seawater equivalent to 5 times the volume of Tokyo Dome (R) per day is raised in temperature by 7°C to be dumped in the sea, but, the influence of the large quantity of high temperature water on fish and shellfish and weather is immeasurable, and no utilization of abundant and heat-stored media is also not economical.SOLUTION: Tubules in a condenser through which cooling seawater flows are divided into the two systems of the upper part and the lower part. The velocity of salt water flowing through the upper tubule is delayed, the quantity of heat storage to the seawater is made large to make high temperature seawater, and distilled water and concentrated salt water are efficiently recovered. Meanwhile, at the lower tubule, the velocity of the flowing seawater is made high, the quantity of the circulating discharged water is made large, thus efficient cooling is performed, and sea dumping is carried out. In this way, the role of the condenser and the role of resource recovery can be simultaneously satisfied.
