Design of UO₂-BeO Critical Experiment at Sandia [Poster]

Cook, William M.; Lutz, Elijah L.; Laros, James H.; Raster, Ashley R.; Miller, John A.; Cole, James R.

The purpose of this proposal is to design a new integral critical experiment to investigate the effects of beryllium oxide and high assay low-enriched uranium fuels. this proposal considers using several existing resources at Sandia: (1) the Critical Experiments (SCX) facility and water tank, (2) spare UO₂-BeO fuel for the Annular Core Research Reactor (ACRR), and 7uPCX fuel rods from previous benchmark experiments.

IER-523: Feasibility of Experiments Focused on Measuring the Effects of UO₂BeO Material on Critical Configurations using 7uPCX [Slides]

Laros, James H.; Cole, James R.; Cook, William M.

Sandia National Labs has access to unused ACRR fuel, which is unique in its enrichment 35% and material composition BeO. ACRR fuel is available in quantities well above what is needed for experiments. Two experiment concepts have been investigated: UO₂BeO fuel elements and pellets with 7uPCX fuel. The worth of UO₂BeO is large enough to be well above the anticipated experiment uncertainties.
