description | Alpha decontamination of waste zircaloy cladding hull was studied using electrochemical dissolution with divalent silver. It was investigated that the electrochemical dissolution process of non-radioactive zircaloy cladding hull, it was found that the zircaloy cladding hull was insoluble in divalent silver and nitric acid solution, probably because the surface layer of the zircaloy cladding hull oxidized to zirconium oxide by the divalent silver in the divalent silver and nitric acid system, which inhibited the dissolution of the zircaloy cladding hull. The electrochemical dissolving process of waste zircaloy cladding hull was established, and the alpha decontamination test of waste zircaloy cladding hull shear section was carried out. The residual specific alpha activity of the waste zircaloy cladding hull is 2.0×105 Bq/kg after electrochemical dissolution. The source items of waste zircaloy cladding hull were analyzed. 241Am and 238Pu are the main nuclides contributing to the specific alpha activity of the waste zircaloy cladding hull. |
