UCOR Monthly Progress, October 2026

Cleanup momentum continues as demolition of Y-12’s Old Steam Plant is officially underway. The 13,000-square-foot facility was constructed in 1943. It was used for a variety of missions including uranium enrichment activities and fuels testing. After deactivation concluded in 2021, crews utilized the facility for maintenance and storage operations. Workers at Y-12 are deactivating the 313,000-square-foot former uranium enrichment and weapons production facility, Beta-4. Crews are conducting deactivation activities such as asbestos removal, electrical isolations, and much more. Transuranic Waste Processing Center (TWPC) crews are safely and compliantly processing transuranic and high activity waste for permanent disposal. Operators are conducting size reduction of the final containers of waste from National Fuel Services.
