The effects of initial stoichiometry on the character and extent of fuel-cladding chemical interaction (FCCI) for mixed-oxide fuels at O/M's of 1.984 and 1.966 irradiated in EBR-2 to peak burnup are described. The strong effect of initial O/M character and extent of FCCI persists to high burnup. Wastage correlations for mixed-oxide fuel based on data from higher O/M fuel must be reduced accordingly to account for the lower O/M levels typical of current LMFBR fuel designs. (FS)
