Uranium transport at the Nopal I uranium deposit in the Sierra Peña Blanca has been studied to evaluate how high-level waste components could be transported through silicic tuff over long time periods. Transport of uranium from areas of primary mineralization was studied using radiometric surveys and analyses of uranium concentrations and distributions in rock samples and minerals within and outside the ore deposit. Results of these studies provide insight into transport processes that could occur at the proposed high-level nuclear waste repository at Yucca Mountain, Nevada.

CNWRA staff published results of uranium transport studies in Applied Geochemistry (Abstract) and presented data and analyses of a major fracture set that crosscuts the uranium deposit at Nopal I in the Journal of Contaminant Hydrology (Abstract). Further details of these studies are available (pdf).
