Method for avoiding malfunctions in the solidification of aqueous, radioactive wastes in a glass, glass ceramic or glass ceramic-like matrix

摘要

Method for preventing malfunctions in the solidification of radioactive wastes contained in an aqueous waste solution in a glass, glass ceramic or glass ceramic-like matrix wherein the wastes are spray- dried and calcinated. Diatomaceous earth or diatomaceous earth-like substances in solid form are added to the aqueous waste solution before the spray drying step in quantities of 45g/l to 70g/l and in grain sizes of which more than 85 percent by weight of the grain size distribution are grain sizes from 6 to 75&mgr;.
