Resumo
Due to its best irradiation and metallurgical processing performance, gamma
uranium-molybdenum alloys are the best candidates for the use as high density /
low enriched research reactor fuels. To the fabrication of U-Mo / Al dispersion fuel
plates, gamma uranium-molybdenum powder obtention is one of the main
processing steps, and to reach this goal, the route considered is hydrationdehydration (H-DH). In this work, some of the experimental results related to the
hydration-dehydration of gamma uranium-molybdenum alloys are presented.
Additions of 5, 6 and 7% wt% Mo were prepared by arc and induction melting, its
as cast structures characterized by optical microscopy, MEV and X-ray diffraction,
and related to the results obtained after being thermally treated under hydrogen
atmosphere, for several conditions of time and temperature. First examinations
showed that the gamma U-Mo alloy hydrogen susceptibility and the yielding in the
powder production increases with the decrease in the Mo addition. Since the
traditional pre-treatment before the hydration was not considered here, some
important conclusions concerning the steps to produce the powder by the HDH
process could be taken.
