ABSTRACT

High-density dispersion fuel experiment, RERTR-4, was removed from the Advanced Test Reactor (ATR) after reaching a peak U-235 burnup of ~80% and is presently undergoing postirradiation examination at the ANL Alpha-Gamma Hot Cell Facility.  This test consists of 32 mini fuel plates of which 27 were fabricated with nominally 6 and 8 g cm^-3 atomized and machined uranium alloy powders containing 6.5 wt% to 10 wt% molybdenum.  In addition, two miniplates contained solid U-10wt%Mo foils. Recent results of the postirradiation examination and analysis of RERTR-4 in conjunction with data from a companion test performed to 50% burnup, RERTR-5, are presented.
