Abstract (en)
[origin: US4571307A] Process for the conditioning of waste constituted by radioactive metal particles insoluble in nitric acid solutions, wherein said particles are suspended in a liquid, the suspension undergoes an evaporation heat treatment by injecting the suspension onto a hot bed of a powder of a metal or an alloy chosen from the group including copper, nickel, zinc, copper alloys, nickel alloys, zinc alloys and stainless steel, and the dry mixture of powder and metal particles obtained after this heat treatment undergoes a melting process at a temperature adequate for melting the metal or alloy powder and for forming clearly defined compounds between the metal of the powder and at least part of the metal constituents of the radioactive particles.
