Section: claims

1. Process for the treatment of solid products or liquid products containing plutonium and/or other radioactive elements, comprising the steps of: a) introducing the solid or liquid products into an aqueous, acid solution that is free of acids containing more than one fluorine moiety per molecule, said products comprising organic or mineral waste materials contaminated by plutonium, metallic plutonium or plutonium oxide with said solid products including plutonium or plutonium dioxide, and  b) microwave heating the aqueous, acid solution containing these products at a temperature and for a time adequate for destroying the solid products and for dissolving the plutonium and/or radioactive elements in the aqueous solution, said aqueous solution being a solution containing 5 to 14 mole/l HNO.sub.3 and 0.01 to 0.1 mole/l of HF.  a) introducing the waste products into an aqueous, acid solution that is free of acids containing more than one fluorine moiety per molecule, said waste products being contaminated by plutonium, metallic plutonium or plutonium oxide, said waste products including at least one contaminated organic solvent, and  b) microwave heating the aqueous, acid solution containing these products at a temperature and for a time adequate for destroying the waste products and for dissolving the plutonium and/or radioactive elements in the aqueous solution. 2. Process for the treatment of waste products containing plutonium and/or other radioactive elemental, comprising the steps of: 3. Process according to claim 2, wherein the aqueous solution is a nitric acid solution.
