Additional Use of Blended Low-Enriched Uranium (BLEU) in Reactors at TVA’s Browns Ferry and Sequoyah Nuclear Plants

On May 18, 2011, TVA issued a final environmental assessment (EA) and finding of no significant impact (FONSI) for the additional use of blended low-enriched uranium (BLEU) in reactors at TVA’s Browns Ferry (BFN) and Sequoyah (SQN) Nuclear Plants in Limestone County, Alabama, and Hamilton County, Tennessee, respectively.  At BFN and SQN, TVA utilizes nuclear fuel that is derived from either commercially-available low-enriched uranium (LEU) or from weapons-usable highly enriched uranium (HEU) declared surplus to defense needs of the United States government.  The HEU is made suitable for nuclear reactor fuel through a process known as “downblending” to produce blended low-enriched uranium (BLEU).   Under an existing agreement, TVA has previously acquired about 33 metric tons of HEU from the U. S. Department of Energy, contracted to have it converted to BLEU, and used it as a partial fuel supply at BFN and SQN since 2005. 

Under the currently proposed action, TVA would acquire an additional 28 metric tons of HEU from the DOE for downblending to BLEU and subsequent use as reactor fuel at BFN and SQN through about 2022.  The subject EA considers the impacts of this proposed action as well as taking no action.  Under both alternatives, TVA would continue to fulfill most of its need for reactor fuel from commercial sources of LEU.
