LOFT pressurizer pressure relief piping system stress analysis and fatigue life report (open access)

LOFT pressurizer pressure relief piping system stress analysis and fatigue life report

A stress analysis was performed on the LOFT Pressurizer Pressure Relief System to determine if it met the requirements of the ASME Boiler and Pressure Vessel Code, Section III, 1974 Edition, for Class 1 and Class 2 components. Deadweight, thermal expansion, seismic, design LOCE, and LOCA loads were considered. The results of this analysis indicate that the LOFT pressurizer pressure relief system will comply with Code specifications provided modifications are made to the hanger support configuration and one small section of pipe. The recommended changes are listed below. Note that some of these hangers were previously required based upon an analysis which subjected this same piping system to a reduced LOCE (20 millisecond valve opening). (1) Addition of Snubbers as per letter HIK-12-75, LOFT Pipe Hanger Requirements on Main Feed Main Steam Pressurizer and ECC Systems. (2) The 1/2'' Line 1/2''-PCS-10 between the tee and CVP-136-19 must be increased in diameter to 1.050 inches (OD of nominal 3/4'' pipe). (3) Modification of Unibals and flat bars as per letter Muff-2-76, required change of flat bar hangers and unibals on pressure relief and pressurizing piping. 9 refs., 6 figs., 1 tab.
