The pressure vessel and closure head designed by Babcock and Wilcox under contract to the Maritime Administration for use in powering commercial ships is described. The design concept for the nuclear reactor is called the Consolidated Nuclear Generator (CNSG); the steam generator is located inside the primary pressure vessel rather than being located in separate pressure vessels connected to the primary vessel by piping. The reactor is designed for propulsion of a 120,000-shp ship and produces 214- MWt power capable of producing a total steam flow of 5.67x100000 kg/hr at 4.83 M Pa and 554 K (1.25x1000000 lb/hr at 700 psi and 538 F). The containment vessel, which houses the nuclear steam supply system, is 11.6 m (38 ft) in diameter and 19.4 m(63 1/2 ft) high, with the reactor pressure vessel centrally located within it. Specific design criteria, regulations, and requirements to be followed in reactor vessel design are discussed. Discussion of how design regulations are to be met and description of special problem areas, such as ship motion, vertical pump nozzle design, and vessel support, are presented. The paper concludes with a description of the current status of the design.
