Abstract
A system and method for storing high level waste. In one aspect, the invention is a system comprising: an outer shell having an open top end and a hermetically closed bottom end; an inner shell forming a cavity, the inner shell positioned inside the outer shell so as to form a space between the inner shell and the outer shell; at least one passageway connecting the space and a bottom portion of the cavity; at least one passageway connecting an ambient atmosphere and a top portion of the space; a lid positioned atop the inner shell, the lid having at least one passageway connecting the cavity and the ambient atmosphere; and a seal between the lid and the inner shell so at form a hermetic lid-to-inner shell interface.
Claims14
A system for storing high level radioactive waste comprising:
- an outer shell having an open top end and a hermetically closed bottom end;
- an inner shell forming a cavity, the inner shell positioned inside the outer shell so as to form a space between the inner shell and the outer shell;
- at least one passageway through the inner shell connecting the space and a bottom portion of the cavity;
- at least one passageway connecting an ambient atmosphere and a top portion of the space;
- a removable lid positioned atop the inner shell, the lid having at least one passageway connecting the cavity and the ambient atmosphere;
- and
- a gasket seal between the lid and the inner shell so as to form a hermetic lid-to-inner shell interface.
A system for storing high level radioactive waste comprising:
- an outer shell having an open top end and a hermetically closed bottom end:
- an inner shell forming a cavity, the inner shell positioned inside the outer shell so as to form a space between the inner shell and the outer shell:
- at least one passageway through shell connecting the space and a bottom portion of the cavity:
- at least one passageway connecting an ambient atmosphere and a top portion of the space;
- a removable lid positioned atop the inner shell, the lid having at least one passageway connecting the cavity and the ambient atmosphere;
- and
- a seal between the lid, and the inner shell so as to form a hermetic lid-to-inner shell interface:
- and
- wherein the lid comprises a plug portion and a flange portion surrounding the plug portion, the plug portion extending into the cavity and the flange portion resting atop the inner shell and the outer shell.
A system for storing high level radioactive comprising:
- a metal plate;
- a first metal tubular shell having a top end and a bottom end, the metal plate connected to the bottom end of the first metal tubular shell so as to hermetically close the bottom end of the first metal tubular shell;
- a second metal tubular shell forming a cavity, the second metal tubular shell positioned within the first metal tubular shell so as to form a space between the first metal tubular shell and the second metal tubular shell;
- at least one opening in the second tubular shell that forms a passageway connecting the space and a bottom portion of the cavity:
- a lid comprising a plug portion and a flange portion surrounding the plug portion, the plug portion extending into the cavity and the flange portion resting atop the first metal tubular shell and the second metal tubular shell;
- at least one passageway connecting the cavity and the ambient atmosphere;
- and
- at least one passageway connecting the space and the ambient atmosphere.
