The invention concerns an apparatus and a method for treating radioactive material (36), in particular for cleaning radioactive contaminated water. The apparatus comprises a process chamber (10) with a combustion zone (12) for generating an oxygen rich gas (34) and an oxidation zone (14), which is arranged to receive the oxygen rich gas (34) from the combustion zone (12). The process chamber (10) further comprises a feed opening (16) for feeding the radioactive material (36) into the oxidation zone (14) and the process chamber (10) is configured to use the oxygen rich gas (34) for oxidizing the radioactive material (36) to obtain oxidized material (38). The apparatus further comprises a separation device (50) operationally connected to an outlet of the process chamber (10) and configured to at least partly separate the oxidized material (38) into a gaseous fluid (56) and a non.sup.− gaseous residue (58). This way a greatly reduced volume of the radioactive material (36) is achieved, enabling safe and efficient handling and/or compact and space-saving disposal of the radioactive material (36).

A basket for incinerating waste inside an incinerator for a duration longer than fifteen minutes with no need for waste to be molten earlier, particularly when waste is introduced inside the incinerator. The basket includes mainly of a glass fiber envelope: it is preferably stiffened by a lightweight metal structure located inside or outside the envelope or built into it. A gripping handle is installed on top of the assembly that is stiffened at the top by a metal tube to which a lightweight metal structure is fixed and by a base formed from a drip pan fixed to the base of the lightweight metal structure.
