ABSTRACT
Initial results from the postirradiation
examination of high-density dispersion fuel test RERTR-3 are discussed. The U-Mo alloy fuels in this test were
irradiated to 40% U-235 burnup at temperature ranging from 140ēC to 240ēC. Temperature has a significant effect on
overall swelling of the test plates. The magnitude of the swelling appears acceptable and no unstable irradiation
behavior is evident.
