A method of disposing of wastes, especially wastes containing radioactive or toxic sub-

stances. such as the wastes generated in the water associated with nuclear power production is described. A feature of the invention is to incorporate the waste into a hardenable setting mass when mixed with water, comprising calcium sulfate hemihydrate. water soluble melamine formaldehyde resin which when cured is hydrophobic, and a cross-linking agent for curing the resin. A radioactive waste container having a radio8

tive waste compartment, a liquid immobilizatil compartment located below the waste compa: ment, a drain passage communicating the COI partments and a closure for selectively openi and closing the drain passage; and a method collecting liquid from radioactive waste in t storage compartment.
