NS SAVANNAH REACTOR CONSTRUCTION AND DESIGN CALCULATIONS

The N.S. Savannah reactor construction and design calculations include the pressure and thermal stress due to internal heat generation in the shell of the reactor. The 2000 psi design pressure reactor is schematically shown. General fabrication assembly of the vessel is to roll and longitudinally weld the shell, then attach the pressed lower head and flange by a circumferential weld. The main coolant nozzles on the reactor consist of two 12-5/8 inches ID outlet nozzles located radically near the top, and two 12-5/8 inches ID inlet nozzles located in a plane parallel to the plane of the outlet nozzle but in the hemispherical bottom head 16 degrees -44 feet below the equator so that these inlet nozzles are very slightly non-radial in a sense. The calculations presented conform in all respects to the requirements of the U.S. Coast Guard and American Bureau of Shipping rules. Where these rules are silent, the American Society of Mechanical Engineers Code is used as a design base. Where all codes are silent, the common agreed upon conservative approach is used. All calculations are presented in the Appendices.
