METHOD OF HARDENING OF CONCENTRATE OF TRANSPLUTONIUM OR TRANSPLUTONIUM AND RARE-EARTH ELEMENTS TO FORM CERMET Russian patent published in 1999 - IPC

Abstract RU 2138866 C1

FIELD: reworking of liquid highly-active wastes. SUBSTANCE: method consists in mixing concentrate of plutonium or plutonium and rare-earth elements with solution of ceramic-forming matrix material-aluminium nitrate and solution of metal-forming matrix material-nickel nitrate; aluminium nitrate is taken in equimolar amount in terms of aluminium oxide relative to oxides of transplutonium or transplutonium and rare-earth elements. EFFECT: possibility of hardening highly active wastes to form cermet with through metal conductivity at high consumption by oxides and low consumption by nickel. 2 ex, 3 tbl
