analysis of Cr-doped UO2 samples with additions of Cr2O3as
0, 500, 1000, 1500, 2500 to 3500 ppm prepared under
sintering conditions of -420 kJ/mol and 1700 ◦C
isreported. The lattice dependence from Cr doping is
established through the Rietveld refinement method wherethe
rate of linear lattice parameter contraction from Cr doping,
Δacr, was found to be considerably smaller andmore subtle
than previously described. This investigation highlights the
need for high resolution and precisespecimen preparation
when measuring and interpreting subtle changes to nuclear
material crystal structures dueto trace doping.},
