Research Summary: Current research in our group
emphasizes chemical processes for used nuclear fuel. 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
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
