Abstract
As large amounts of uranium-containing (both high and low-level) waste are generated from activities such as fuel fabrication, fuel reprocessing, and R&D, concern is growing over the safe disposal of these radioactive materials. Over the past few decades, numerous disposal options have been investigated, including pyrometallurgical high-temperature fusion/vitrification, hydrometallurgical processing, biological remediation, polymerization, clay back-filling, and zeolite adsorption. This paper reviews the techniques, thermodynamics, and kinetic aspects of processing uranium-containing waste. In particular, the removal of uranium waste by zeolite adsorption and mechanisms are discussed. In addition, the pyro- and hydrometallurgical conceptual flow sheet is proposed for the disposal of uranium-containing waste.
