Amended Record of Decision for the Continued Interim Operation of the Y-12 National Security Complex

Résumé

The National Nuclear Security Administration (NNSA), a separately organized agency within the U.S. Department of Energy (DOE), is amending its July 2011 Record of Decision for the Continued Operation of the Y-12 National Security Complex (2011 ROD) to reflect its decision to continue to implement on an interim basis a revised approach for meeting enriched uranium requirements (while addressing issues related to seismic analysis), by upgrading existing enriched uranium (EU) processing buildings and constructing a new Uranium Processing Facility (UPF). Additionally, NNSA has decided to separate the single-structure UPF design concept into a new design consisting of multiple buildings, with each constructed to safety and security requirements appropriate to the building's function. This revised approach is combining elements of the two alternatives previously analyzed in the Final Site-Wide Environmental Impact Statement for the Y-12 National Security Complex, DOE/EIS-0387 (Y-12 SWEIS).
