Abstract
A method of forming a sealed canister and a method of storing radioactive materials is provided. The method of forming includes placing a top plate on a top opening of a side wall, a bottom of the side wall being sealed to a base 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. Finally, a weld is formed between the beveled top edge and the top opening of the side wall to seal the top plate to the side wall.

A method of forming a sealed canister, the method comprising placing a top plate on a top opening of a side wall, a bottom of the side wall being sealed to a base plate, wherein the top plate includes a top surface with a top edge having a bevel and with a channel set in from the top edge;
- and
- forming a weld between the beveled top edge and the top opening of the side wall to seal the top plate to the side wall.
A method of storing radioactive materials, the method comprising:
- placing radioactive materials in a cavity formed by a side wall having a bottom sealed to a base plate;
- placing a top plate on a top opening of the side wall, the top plate including a top surface with a top edge having a bevel and with a channel set in from the top edge;
- forming a weld between the beveled top edge and the top opening of the side wall to seal the top plate to the side wall, so that the cavity is sealed;
- placing a first probe in the channel and a second probe opposite the first probe and adjacent the side wall, such that the weld is disposed between the two probes;
- activating the first and second probes to determine an integrity of a volume of the weld between the probes;
- and
- moving the first and second probes synchronously around the top plate to determine the integrity of an entire volume of the weld.
