Abstract (en)
[origin: EP0327691A2] The invention relates to a process for the disposal of radioactive wastes, in which the wastes are consolidated or compressed and then enclosed in a container. The object of the invention is to improve the process so that the formation of a hydrogen atmosphere in the free gas volume of the container is prevented. This is achieved, according to the invention, by a method in which the wastes are at least partially surrounded by cement containing potassium permanganate in order to eliminate the hydrogen formed during storage. Porous, non-reducing substrate material on the surface of which potassium permanganate is applied is used as an alternative covering material. The waste material and the covering material are placed in a common container.
