| Summary: | In order to develop a production process of exp 99 Mo by fission of low-enriched uranium, the first purification step, which consists of dissolution of a uranium metal foil target, was studied. It was found that alkaline NaClO gave good results, reaching the dissolution of up to 300 mu m of uranium foil. The different conditions for the dissolution were studied and the optimum ones were found. The influence of NaClO and NaOH concentration, temperature, dissolving solution volume per unit of surface and dissolution time were investigated. During this step, a gas, identified as H sub 2 , was generated, and a precipitate characterized as Na sub 2 U sub 2 O sub 7 was observed. A stoichiometric reaction for this uranium dissolution is proposed. |
