In this conceptual design the direct Brayton cycle is combined with a nuclear heat source and a waste-heat boiler to provide total power for a passenger ship. A steam power plant of an existing ship is replaced by a closed helium cycle. The cycle is developed and machinery components are selected based upon current manufacturing technology. Machinery, weight, volume, cost and plant efficiency are compared. This study showed that the direct Brayton cycle produced the same power at a lower weight and volume, at a higher cost and at a higher efficiency than the comparable steam plant.
