    摘要: Apparatus and methods for treating radioactive material, in particular for cleaning radioactive contaminated water, are described. One apparatus comprises a process chamber with a combustion zone for generating an oxygen rich gas and an oxidation zone, which is arranged to receive the oxygen rich gas from the combustion zone. The process chamber further comprises a feed opening for feeding the radioactive material into the oxidation zone and is configured to use the oxygen rich gas for oxidizing the radioactive material to obtain oxidized material. The apparatus further comprises a separation device operationally connected to an outlet of the process chamber and configured to at least partly separate the oxidized material into a gaseous fluid and a non-gaseous residue. This way a greatly reduced volume of the radioactive material is achieved, enabling safe and efficient handling and/or compact and space-saving disposal of the radioactive material.

    摘要: The present invention provides a polymeric extractant with pendant chelator groups for selective sequestration of actinides and/or lanthanides comprising: a first block polymer comprising one or more CMPO monomers each having a first backbone bound to a pendant carbomylmethylphosphine oxide group; a second block polymer comprising one or more second monomers each having a second backbone bound to a second pendant group, wherein the first backbone is polymerized to the second backbone to form a polymer backbone with pendent blocks of the second pendant group and pendent blocks of pendent carbomylmethylphosphine oxide group that sequester the actinides and/or lanthanides; and optionally a third block polymer comprising one or more third monomers each having a third backbone bound to a third pendant group, wherein the one or more third monomers is polymerized to the first backbone and the second backbone.
