CALCULATIONS OF STRUCTURAL ADEQUACY FOR CRITICAL AREAS OF THE MARVEL SCHEBLER DESIGNED CONTROL ROD DRIVE MECHANISM FOR NS SAVANNAH

Control rod drive mechanisms, electrically driven rotating nuts and translating screws, effect motion of the nuclear reactor's control rods to fulfill externally imposed power-demand and safe-reactor signals. Calculations for the M-S control rod drive mechanism were made according to Marine Engineering Regulations and Fired Pressure Vessel Code specifications. Thread stresses for threaded connections and bolts were computed utilizing Federal Screw Thread Standards. Detailed calculations and supporting information pertaining to the pressure boundary, stator water jacket, and drive line, show that this mechanism meets or exceeds applicable structural and safety rules and specifications.
