Systems and method for reducing tritium migration

摘要

A system and method for reducing tritium migration. In one aspect, the invention is a method of reducing tritium mitigation from a spent nuclear fuel pool containing a body of tritiated water having an exposed surface, the method comprising hermetically sealing the exposed surface of the body of tritiated water with a cover movable between an open-state and a close-state.

主权项

1. A system for reducing tritium migration comprising:
a spent nuclear fuel pool comprising a body of tritiated water having an exposed surface; a cover movable between an open state in which the cover does not obstruct access to the exposed surface of the body of tritiated water and a closed state in which the cover covers the exposed surface of the body of tritiated water; wherein the cover is a tent structure comprising a frame and a vapor impermeable membrane coupled to the frame, the frame comprising a base that surrounds the spent nuclear fuel pool in the closed state, the tent structure forming a cavity between the vapor impermeable membrane and the exposed surface of the body of tritiated water in the closed-state; and wherein the tent structure comprises an internal funnel that is configured to flow tritiated water vapor that condenses on an inner surface of the vapor impermeable membrane back into the body of tritiated water of the spent nuclear fuel pool.
