ABSTRACT
U-Mo dispersed fuel can not fulfill the U density
requirements for high flux reactors. Besides, in-pile
experiments have shown a large interaction between the
fuel particles and the matrix. Replacing dispersed fuel
by an U-Mo foil has been proposed and is currently under
investigation as a possible solution to these problems.
Friction stir welding is being experimented at ANL to
fabricate fuel plates. Supported by the ENDE - CAC -
CNEA experience in FSW, experiments have been started.
Successful weld were obtained between aluminum and
stainless steels (as subrogate material instead U-Mo)
which allowed the selection of optimum parameters. This
were applied to encase stainless steel and U-Mo foils in
aluminum plates. The first objective was the
implementation of the process, optimization of operative
parameters and selection of the adequate tests to
qualify the welding. The second objective was to apply
these techniques to fabricate U-Mo /Al alloys diffusion
couples. First results are presented.
