Engineering spent-fuel shipments at the UMR reactor facility
- Univ. of Missouri, Rolla, MD (United States)
In July of 1992, the University of Missouri-Rolla Reactor (UMRR) converted from highly enriched uranium (HEU) to low-enriched uranium (LEU) fuel. The on-site inventory of irradiated HEU fuel consisted of 28 materials test reactor plate-type elements, each containing {approximately}170 g of 90% enriched {sup 235}U. Each element weighed {approximately}5.4 kg and measured 7.6 x 7.6 x 84 cm. The HEU fuel filled the fuel storage rack, leaving no room to offload LEU fuel elements from the core for various maintenance activities. A priority effort was initiated to ship the HEU fuel off-site. Finally, during the summer of 1996, the HEU fuel was shipped to the U.S. Department of Energy`s Savannah River site.
