Abstract
Abstract A temperature differential power plant is combined with a nuclear power plant and employs the temperature differential between hot water discharged from cooling the nuclear reactor, steam obtained from the nuclear reactor, and cold water taken in from an outside source such as the sea. The generated output and thermal efficiency of the entire power equipment is thereby increased; the temperature of the hot water discharged from cooling the nuclear reactor is decreased to aid in the recirculation thereof and eliminate hot water pollution; and, only the cold water taken in is discharged with its temperature being controllable so as not to create a cold water pollution problem. Temperature differential power plants can be used in stages with the hot water discharged from cooling the nuclear reactor passing successively from one stage to the next.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
122 words
Ocean nuclear power equipment comprising a nuclear reactor power plant, a reservoir for storage of hot discharge water from cooling the nuclear reactor, the water pooled in said reservoir being circulatorily used as nuclear reactor cooling water, a source of cold water, a temperature differential power plant including electric generating means which makes use of a temperature differential between said hot discharge water and steam obtained from the nuclear reactor, and said cold water, means for conducting said hot discharge water through the temperature differential power plant to the reservoir whereby the temperature of said discharge water is lowered for recirculation to the nuclear reactor as said cooling water, and means for discharging said cold water from the temperature differential power plant.
