There is some concern that the FB-Line D1 dissolver may have been pressurized above the liquid head pressure by a reaction that occurred in the dissolver. The D1 Pu limit of 8.8 kg is based on a tank with an inner slab thickness of 3.34 inches and a wall thickness of 0.40 inches for a total slab thickness of 4.14 inches. When the incident occurred there was less than 1,500 gm Pu (1,323 gm) in the dissolver. Some calculations were made to determine the safe slab thickness for 1,500 gm Pu in the D1 dissolver. Calculations show that 1,500 gm Pu can be safely contained in a 6 inch thick D1 dissolver provided the cabinet panels are in place
