This study considers the requirements that would be imposed on the power plant for an Arctic bulk-carrier. The ship is assumed to be required to make its way unaided through the most severe conditions specified for the Arctic control zones. The various types of reactors that are in use are considered as candidates for marine application. These are criticized on the basis of weight and space requirements, and on demonstrated reliability. On this basis the pressurized light water reactor of the integral design is selected as the most favourable alternative. Reactor design considerations: compactness, power density, reactivity control and core lifetime, are discussed with special reference to marine application. The power transmission system is of utmost importance in this application, and so is examined in detail. Geared reduction drive and electric drives are considered. A variable frequency a.c. system is selected due to its inherent advantages. Propeller selection is also considered. The plant proposed on the basis of all considerations is a nuclear powered turbo-electric system. Power is provided by two integral PWR's to two steam turbines driving propulsion alternators. The three shafts are driven by synchronous motors, and are fitted with fixed pitch propellers. All components are within the capability of present technology to design and build.
