Nuclear propulsion system, designed for installation in a 38,000 ton DWT tanker, is based on a closed high-pressure gas turbine cycle with intercooling and regeneration. A direct gas-cooled reactor is utilized as the heat source in the closed-cycle gas turbine. Helium is used as the working fluid due to its chemical inertness, heat transfer, and fluid flow characteristics. The 1000 psia maximum system pressure is a compromise between the high pressures needed for heat removal, fluid flow, and component size, and the low pressures for easier fabrication and reduced leakage. Estimated cycle thermal efficiency is 31% at the low pressure turbine shaft and 29.8% at the propeller. General performance characteristics, including a schematic flow diagram and design points, are provided, as well as power plant layout and operation, time schedules, and research, manufacturing, and installation costs.
