Jung, J

As part of Sandia National Laboratories' Severe Accident Sequence Analysis (SASA) Program, structural analyses of the Watts Bar, Maine Yankee and Bellefonte containment structures were performed with the objective of obtaining realistic estimates of their ultimate static pressure capabilities. The Watts Bar investigation included analyses of the containment shell, equipment hatch, anchorage systems and personnel lock. The ultimate pressure capability is estimated to be between 120 and 140 psig, corresponding to shell yielding and equipment hatch buckling, respectively. The Maine Yankee investigation provided a 96 to 118 psig failure pressure estimate for the containment shell. The pressure capability of the Bellefonte containment structure is estimated to be between 130 and 139 psig corresponding to dome tendon yielding and cylinder wall tendon yielding, respectively.
