ABSTRACT:
Disclosed is a process for making a cinder aggregate from neutralized PUREX waste. The PUREX waste is concentrated to about 30 to about 40 percent solids and a colloid of such de-alcoholated alkoxides of silicon, boron, and aluminum are added to the PUREX waste as are necessary to produce a mixture containing about 0.0001 to about 1 percent aluminum hydroxide, about 5 to about 15 percent silica, and about 1 to about 3 percent boric oxide. The resulting mixture is heated to about 400 to about 700.degree. C. which produces a cinder. The cinder will be transported to a vitrification center where it can be disintegrated in ammonium hydroxide and the nuclear waste can be permanently encapsulated in glass.
