| Abstract Scope |
Voloxidation of spent nuclear fuel (SNF) is being considered as an alternative front end for separation of volatile fission products and recovery of actinides. Several studies have described using air alone or air in combination with NO2 for this processing. However, despite research being performed on these techniques, questions remain about the chemical mechanism of the voloxidation process. Thus, Oak Ridge National Laboratory (ORNL) is researching the process to determine the optimal voloxidation process conditions, while identifying the products at various stages of the process. These efforts will also assist in the determination of the partitioning behavior of volatile fission products during voloxidation. A special focus is given to elucidating the uranium crystal phases and associated morphological features during the voloxidation process. The results of tests with representative SIMFUEL will be discussed in this presentation. |
