National Nuclear Security Administration September 2, 2020 – Federal Register Recent Federal Regulation Documents

The National Nuclear Security Administration (NNSA), a semi- autonomous agency within the U.S. Department of Energy (DOE), is announcing this amendment to the December 19, 2008, Record of Decision (ROD) for the Complex Transformation Supplemental Programmatic Environmental Impact StatementOperations Involving Plutonium, Uranium, and the Assembly and Disassembly of Nuclear Weapons (Complex Transformation SPEIS2008 Programmatic ROD). In this Amended ROD, NNSA announces its programmatic decision to implement elements of a Modified Distributed Centers of Excellence (DCE) Alternative whereby Los Alamos National Laboratory (LANL) will produce a minimum of 30 war reserve pits per year for the national pit production mission during 2026 and implement surge efforts to exceed 30 pits per year as needed. NNSA will implement this decision without construction of the Chemistry and Metallurgy Research and Replacement Nuclear Facility (CMRR-NF). NNSA has previously evaluated this action at the programmatic level in the Complex Transformation SPEIS and at the site-specific level in the LANL Sitewide Environmental Impact Statement (SWEIS), and recently completed a review of those prior analyses in a separate Supplement Analysis (SA) for each document. Pit production alternatives were previously analyzed in the Complex Transformation SPEIS.
