520 3 |a A unique process was developed for preparing multi-kilogram quantities of > 90% dense fragments of enriched and depleted UO/sub 2/ sized 20 mm to 0.038 mm for fuel debris experiments. Precipitates of UO/sub 4/ . xH/sub 2/O were treated to obtain UO/sub 2/ powders that would yield large cohesive green pieces when isostatically pressed to 206 MPa. The pressed pieces were crushed into fragments that were about 30% oversized, and heated to 1800/sup 0/C for 24 h in H/sub 2/. Oversizing compensates for shrinkage during densification. Effort was dramatically reduced by working on a large scale and by presizing the green UO/sub 2/ instead of directly crushing densified pellets.
