Title: Significant results of neutronics analysis for fuel conversion of the UFTR

Abstract

The University of Florida Training Reactor (UFTR) is a 100-kW light-water-cooled, graphite and light-water-moderated Argonaut-type reactor that utilizes high-enriched (93%) materials test reactor-type (uranium-aluminum alloy) fuel plates in a two-slab core configuration consisting of 11-plate fuel bundles loaded into six fuel boxes. The purpose of this work was to perform the neutronics analysis necessary to support a licensing submittal to the US Nuclear Regulatory Commission (NRC) for conversion of the UFTR from high-enriched uranium (HEU) to low-enriched uranium (LEU) fuel as required by 1986 revisions to the Code of Federal Regulations (10CFR50.64). After elimination of pin-type SPERT fuel as an option, the fuel selected for the conversion analysis was the uranium silicide-aluminum dispersion standard plate-type fuel, which has been well evaluated for use in nonpower reactor fuel conversions.
