Abstract: A canister for storing radioactive materials includes a base plate, side wall and a top plate. The top plate includes a top surface with a top edge having a bevel, and with a channel set in from the top edge. The top plate is sealed to the sidewall by a weld formed between the beveled top edge and the top of the side wail. The base plate is sealed to a bottom of the sidewall, so that a sealed vessel is formed.
