PROCESS FOR COATING RADIOACTIVE WASTE TO PROVIDE SAFE TRANSPORT AND STORAGE

摘要

P The invention relates to the field of treatment of residues from the nuclear industry and having a dangerous radioactivity. /P P According to the coating process, a metallic container containing the radioactive waste is wedged in a larger metallic external barrel and a slag or a molten slag is poured into the free space formed between the two containers. Slag and slag can come from various sources (blast furnaces, foundry, manufacture of ferro-alloys and non-ferrous metals ...) and are advantageously chosen from molten products with a low basicity index. Substances can be added to them to lower the solidification temperature. /P P Application to the treatment of solid or pasty waste with low or medium radioactivity. /P
