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

Cook, William M.; Lutz, Elijah; Foulk, James W.; Raster, Ashley R.; Miller, John; Cole, James

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.

Integral Experiment Request 523 CED – 1 Report

Cook, William M.; Foulk, James W.; Lutz, Elijah; Cole, James; Raster, Ashley R.; Miller, John; Harms, Gary A.; Marshall, William J.; Zerkle, Michael

This report documents the preliminary design phase of the Critical Experiment Design (CED-1) conducted as part of integral experiment request (IER) 523. The purpose of IER-523 is to determine critical configurations of 35 weight percent (wt%) enriched uranium dioxideberyllium oxide (UO₂-BeO) material with Seven Percent Critical Experiment (7uPCX) fuels at Sandia National Laboratories (Sandia). Preliminary experiment design concepts, neutronic analysis results, and proposed paths for continuing the CED process are presented. This report builds on the feasibility and justification of experimental need report (CED-0) completed in December 2021.

IER-523: Design of a UO₂-BeO Critical Experiment at Sandia [Slides]

Cook, William M.; Lutz, Elijah; Foulk, James W.; Raster, Ashley R.; Cole, James; Harms, Gary A.; Miller, John

This lecture is on the design of a Uranium Dioxide-Beryllium Oxide UO₂-BeO Critical Experiment at Sandia. This presentation provides background info on the Annular Core Research Reactor (ACRR). Additionally, this presentation shows experimental and alternative designs and concludes with a sensitivity analysis.

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

Foulk, James W.; Cole, James; 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.
