The motivation is to reduce the hazard associated with the used nuclear fuel, to reduce the storage time needed for the material, and to reuse and recycle some of the useful raw material still existing in the spent nuclear fuel thereby improving the utilization of existing natural resources. Our research involves: 1.Developing a fundamental understanding of the extraction processes to improve selectivity and efficiency. We are also working on extraction contactor studies to improve and understand kinetics and fluid dynamics in typical equipment used for this work. 2.Improvement in the remote monitoring of nuclear processes. 3.The specific effect of radiolytic degradation of the chemicals used in the process and how this effect can be addressed in process calculations. 4.Preparation of radioisotopes for medical purposes. Radioactive material can be used for a variety of purposes in medicine including cancer therapy, pain relievers and imaging.
