Tailings containing non extracted U and its radioactive progenies are currently stored under water in a basin extending over 18ha. To predict U (100-400 ppm) and <sup>226</sup>Ra (10-70Bq.g<sup>-1</sup>) mobility, a detailed chemical, mineralogical and radiological characterization of the phases is required. For this, tailings sampling was performed to collect undisturbed samples close of <em>in situ</em> conditions. Preliminary characterizations evidenced good correlation between facies (to link with the extraction mode), granulometry, U concentration and <sup>226</sup>Ra activity. U and <sup>226</sup>Ra are concentrated in the silty-clay facies mainly as inherited monazites and neoformation of uranyl phosphates known for their low solubility. Clay minerals and Fe-oxi-hydroxides are also encountered and may play an important role in radionuclide trapping by sorption processes. These preliminary results confirm the immobilization of U and <sup>226</sup>Ra within the tailings, even though, additional experiments are needed to determine the extent of U and <sup>226</sup>Ra sorbed on Fe-oxi-hydroxides and on clay minerals.</p></div>","PeriodicalId":101039,"journal":{"name":"Procedia Earth and Planetary Science","volume":"17 ","pages":"Pages 308-311"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeps.2016.12.067","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80963546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
