Abstract
Filtered storage containers for hazardous waste, such as radioactive waste, more particularly plutonium in the form of oxides and salts, are made of stainless steel and include lids which are retained by retaining rings that utilize bayonet or ratchet closures that cooperate with rims that are integral with cans to hold the lids in place. Sealing arrangements are provided that each include an O-ring of a circular cross section which seals radially between the lid and rim, as well as a seal of cruciform cross section, which seal provides compression sealing between the lid and an annular shelf within the rim upon locking the retaining ring to the rim with the bayonet or ratchet fitting.
