Abstract
This paper offers a preliminary evaluation of the recent post-irradiation-examination (PIE) results collected for the low enriched uranium (LEU)-molybdenum (U-Mo)
dispersion fuel test, EMPIrE, with emphasis on PVD coated U-7Mo particles. The fuel swelling up to a burnup of ~80% U-235 was stable and in the expected range of
values, as compared to other irradiation experiments to similar burnups. Plateaveraged non-destructive examination results did not reveal a difference in swelling
performance between the 700 series plates (non-heat treated particles) and the 800 series plates (heat treated particles). Preliminary destructive examination results
found that the addition of a ZrN coating on the fuel particles resulted in a reduction in the fuel-Al interaction at high burnup, as determined by comparison of a limited
number of cross-section images from EMPIrE to dispersion fuel plates without coating from previous tests. The preliminary destructive examination results indicate
that the condition (thickness, level of coverage, etc) of the coating may impact the level of interaction layer thickness formation in the fuel.
