NS SAVANNAH, SWAY BRACING ANALYSIS

Steam generators on the N.S. Savannah require bracing to withstand the forces resulting from a 90 degree inclination with an added acceleration force of one g. Analysis included checking stresses in the steam generators, in the support steel, and in the connected primary piping, and investigated alternate schemes for anchoring the steam generators. With the present design, the calculated stress in the 1-1/4 inch thick baseplate supporting the steam generator would be 145,000 psi which is in excess of the 60,000 psi ultimate strength of the material. Installation of longer shoulder bolts for anchoring the steam generator saddle support plate directly to the foundation steel relieved the bending stress in the baseplate under the saddle support plate.
