NS SAVANNAH NUCLEAR MERCHANT SHIP TERMINAL EXPANSION STRESS ANALYSIS OF THE PRIMARY PIPING SYSTEM

Results are presented of an examination made to determine the effects of thermal expansion on the primary piping system of the N.S. Savannah based on the worst possible temperature conditions to which the system can be subjected. The effects of weight and acceleration upon the nozzles in the system were also reviewed. The investigation is based upon the system specifications, basic design data, weight stress analysis and thermal expansion stress analysis data prepared by the Babcock & Wilcox Company and the Electric Boat Division of the General Dynamics Company. Appendixes are included which provide the calculation sheets covering (1) basic conditions for analysis, (2) piping system stress analysis, and (3) nozzle stress analysis. As far as thermal expansion stresses are concerned, the investigation concludes that both the suction and discharge systems are satisfactory. Also, under the conditions of thermal expansion, internal pressure, weight, and acceleration used as the basis for this investigation, it was found that the nozzle is not overstressed.
