Development advances in uranium-molybdenum monolithic and dispersed fuels are presented so as to look forward additional alternatives to cover HEU-LEU conversion possibilities.
Preliminary results on post-irradiation examination of one zircaloy-4 cladded U- 7Mo monolithic 20% enriched miniplate irradiated during the RERTR-7A experiment shows good performance.
With this encouraging results, new developments in monolithic fuels are being designed.
Process capabilities and performance prediction in dispersed fuels are being tried with the following characteristics:
- Aluminum matrix alloyed with germanium, instead of silicon.
- Coated U-Mo particles with silicon, germanium and nickel, and aluminum alloyed with these elements, so as to reduce interaction kinetics.
- Incorporation of porous alumina in the matrix, to adsorb gaseous fission products.
