METHOD OF OPERATION FOR FLOOR-AREA CONTAMINATED BY RADIONUCLIDS PUTTING-IN DEAD STORAGE TREATMENT Russian patent published in 1997 - IPC

FIELD: decontamination and preserving treatment technology. SUBSTANCE: method includes contaminated volume of floor-area filling by solidificating composition with components: carbamideformaldehyde resin 15-30%, acid curing agent 3-4% foaming agent 3-4% and water rest. Composition is produced like foam by two ejectors using which one is for mixing of water, foaming agent and resin, and the next is for mixing of water and acid curing agent. Two obtained mixtures feed third ejector for stirring by compressed air using. So obtained foamy composition is transported to conservation zone by air high-pressure pipe-line using. Method provides construction structure less loading, diminishing of expenditure for treatment, well possibility for floor area quick reset to initial but decontaminated state by less labour spending, well accessible treatment components and nontoxic products of fire effect. EFFECT: more convenient method. 1 dwg
