Lined hazardous materials container
View Patent ↗Provided is a device and method for containing hazardous waste, including a container for hazardous waste, comprising a hangable bag having an interior volume, the hangable bag being constructed at least in part of collapsible material and configured to be lifted and configured to support an interior bladder, and the interior volume being variable; and an interior bladder, the interior bladder connectable with a through port to a lid.
1. A waste storage container, comprising:
a substantially cylindrical liner;
a liftable lid adapted to be placed atop the cylindrical liner and to be lifted from the cylindrical liner;
a flexible bag system comprising at least a first bag and a second bag, the first bag having an inner volume and adapted to hang from the liftable lid and to support a weight of the second bag, the second bag placeable inside the inner volume of the first bag and sealable, and the first bag and the second bag sized to be received by the cylindrical liner, wherein:
the second bag is connectable with a through port to the liftable lid,
the flexible bag system is removable from the cylindrical liner, and
the flexible bag system comprises a plurality of expansion locations, such that the plurality of expansion locations allow a horizontal dimension of the flexible bag system to exceed a horizontal dimension of the cylindrical liner when the flexible bag system is outside the cylindrical liner.
2. The waste storage container of claim 1 wherein the liftable lid further comprises a connection section, wherein the connection section is positioned to allow a connection with the second bag and the liftable lid, and to allow a pass through section from above the lid to an inner volume of the second bag.
3. The waste storage container of claim 2 wherein the liftable lid further is adaptable to mate with existing nuclear power plant fill heads.
4. The waste storage container of claim 1 wherein the flexible bag system comprises a puncture resistant material and a water-proof material.
5. The waste storage container of claim 1 , wherein the first bag is dimensioned to have a tapered shape.
6. The waste storage container of claim 1 , wherein the second bag comprises at least 60 mil PVC material.
7. The waste storage container of claim 1 , wherein the through port in the liftable lid comprises a down spout, and the second bag is constrainable against the down spout with a ring clamp.
8. The waste storage container of claim 1 , wherein the liftable lid includes supports, the supports arranged to lift the first bag;
and wherein the first bag comprising lifting straps and the supports on the liftable lid are lift strap connectors, mateable with the lifting straps.
9. The waste storage container of claim 1 , wherein the cylindrical liner further comprises a ventilation shaft positioned such that, when the first bag is inside the cylindrical liner, the ventilation shaft supplies air to an interior location of the cylindrical liner below the first bag.
