Abstract:
1. A method including use of a collapsible liner disposed within an overpack container defining an interstitial space between the liner and container, and a cap operatively coupled with the overpack and defining at least one depressurization port and at least one feed material port in fluid communication with the interior volume of the liner, the at least one depressurization port being in fluid communication with the interstitial space and arranged for depressurization and/or pressurization of the interstitial space, the method comprising: applying subatmospheric pressure to the interstitial space to cause the liner to expand and draw feed material from a feed material source into an interior volume of the liner; and pressurizing the interstitial space to cause the liner to contract and thereby dispense the feed material from the interior volume through the feed material port, wherein the feed material is dispensed from the interior volume and through the feed material port into a collapsible liner disposed within another overpack container.
