ABSTRACT
Recent irradiation tests of U3Si-Al dispersion fuel have shown performance
limitations of this fuel when high volume fractions of U3Si2 operate
at high temperatures and high fission rates. This potential problem is associated with
high rates of Al-U3Si2 interdiffusion that may lead to complete
consumption of matrix aluminum and the formation of excessive porosity.
