ABSTRACT
The evolution of a cellular dislocation structure and
subsequent recrystallization have been identified as important aspects of the
irradiated UMo alloy microstructure that can have a strong impact on dispersion
fuel swelling. Dislocation kinetics
depends on the preferential bias of dislocations for interstitials compared to
vacancies. This paper presents theoretical calculations for the evolution of a
cellular dislocation structure, and recrystallization in U-10Mo. Implications for fuel swelling are
discussed.
