METHOD FOR RADIOACTIVE WASTE SOLIDIFICATION Russian patent published in 1996 - IPC

Abstract RU 2065221 C1

FIELD: nuclear engineering; recovery of solid radioactive waste. SUBSTANCE: method involves waste mixing with silicon powder, its placing in sealed reactor, heat treatment of mixture under self-spreading high-temperature fusion conditions at nitrogen pressure not over 150 MPa. Fusion product is packed directly in reactor at isostatic pressure not over 200 MPa. When mixing waste with silicon, thinner may be introduced, in addition, into mixture; silicon carbide is usually employed as thinner. EFFECT: improved reliability of radionuclide immobilization in solid array at reduced power requirement. 4 cl, 4 ex
