Analysis of LOFT containment nozzles 11A, 11B, 11D, 12A, 13B, 13C, and 13D by Bijlaard method (open access)

Analysis of LOFT containment nozzles 11A, 11B, 11D, 12A, 13B, 13C, and 13D by Bijlaard method

The purpose of this analysis was the calculation of stresses in the LOFT Containment Vessel at the point of nozzle penetration produced by loads on the nozzles and to show that those stresses are within the 1965 ASME Boiler and Pressure Vessel Code allowables. The stress determination was done by the method developed by P. P. Bijlaard on the worst load case for each diameter nozzle. The operating basis earthquake (OBE) at nozzle 11D produced the most severe load case. All load cases resulted in containment vessel stresses that were less than the allowables as stated in N-414 of the 1965 ASME Boiler and Pressure Vessel Code.
