Structural analyses of the Watts Bar, Maine Yankee and Bellefonte containment structures were performed as part of the Severe Accident Sequence Analysis (SASA) program. The objective of these analyses was to obtain realistic estimates of the ultimate pressure capabilities of these containments. The three containments considered are representative of the different containment types. The Watts Bar containment is a hybrid steel type, the Maine Yankee containment is reinforced concrete and the Bellafonte containment is prestressed concrete. It was concluded that a realistic ultimate pressure range for the Watts Bar containment is between 120 and 140 psig. The ultimate pressure capability of the Maine Yankee containment is between 96 and 118 psig. The pressure capbility of the Bellefonte containment is 130 to 139 psig.
