Criticality of moderated and undermoderated low-enriched uranium oxide systems
Technical Report
·
OSTI ID:6927532
Uranium oxide was enriched to 4.46 wt % /sup 235/U compacted to a density of 4.68 g/cm/sup 3/. The uranium oxide was packed into cubical aluminum cans and water added to the oxide until an H/U atomic ratio of 0.77 was achieved. A 5 x 5 x 5 array of uranium oxide cans for the experiments were used when no plastic moderator material was placed between cans. High enriched uranium drivers were used to achieve criticality. Criticality was achieved for smaller arrays without a driver when 24.5 mm plastic moderator material was placed between the cans. Twelve critical experiments are reported, six in each reflector.
