ABSTRACT:
A method and apparatus for removing waste products from solutions of fission products, especially nitric solutions, which contain ruthenium. The method utilizes concentration and solidification, especially vitrification, with the solution being concentrated to a solid content of at least about 15 to 20% in a vacuum at a pressure of at most about 50 mm Hg. The apparatus includes a vacuum evaporator, a subsequent mixing device which is fed by nitrate decomposing agents and vitrifiers, and a vitrifying oven. A drying device may be interposed between the mixing device and the oven. Preferably an ammonia derivative, especially urea, is added to the concentrate before solidification.
