METHOD FOR ISOLATING SOLID RADIOACTIVE WASTES FROM ENVIRONMENT Russian patent published in 2000 - IPC

FIELD: burial of radioactive wastes in ground. SUBSTANCE: method for burying solid wastes in ground so that radiation monitoring for their behavior directly in reinforced-concrete cavity is possible in the course of their long-time storage includes construction of underground reinforced-concrete cavity divided by means of reinforced- concrete partitions into sections, installation of perforated pipes in sections, filling of sections with solid radioactive wastes, grouting of solid radioactive wastes in non-radioactive cement solution mixed up with inorganic sorbent, closing of sections with reinforced-concrete slabs of roofs having conical ports, detection of voids in section fills, drilling of conical holes through thermoplastic material and immobilized solid wastes of wells before opening voids detected, introduction of non-radioactive cement solution mixed up with inorganic sorbent into voids and wells, sealing of reinforced-concrete slabs of section roofs, and long-time holding of solid wastes for their radiation and environmental safety monitoring by taking samples from cavity. EFFECT: improved safety and environmental friendliness. 4 cl, 3 dwg
