A light-water reactor power plant considered in this study utilizes seawater for steam-cycle cooling, and uranium in the seawater is extracted as the fuel of the reactor. Increase of the cooling seawater intake results in increase of the uranium extraction from the seawater, but it causes increase of the pumping power and might cause decrease of the thermal efficiency of the reactor. We examined the relation among the amount of cooing seawater, extraction efficiency of uranium, and power plant efficiency, in order to find out the 'self-sufficient' conditions of the power plant. It was concluded that self-sufficient power plant condition is feasible even now and it will be more attractive as the efficiency of uranium extraction from seawater increases further in the future.
