EA-1381: Final Environmental Assessment

Atlas Relocation and Operation at the Nevada Test Site

The National Nuclear Secuxity Administration (NNSA) prepared an Environmental Assessment (EA) (DOEIEA-1381) to analyze the proposed action to relocate the Atlas pulse power machine from Los Alamos National Laboratory (LANL) to the Nevada Test Site (NTS). At the NTS, Atlas would be reassembled in a newly constructed building within a designated Industrial, Research, and Support site in Area 6. After reassembly, Atlas would be commissioned to ensure proper operation and then used to conduct approximately 40 pulsed power experiments per year, with a potential to increase to approximately 100 experiments per year, should the Stockpile Stewardship Program require it. The EA also addresses alternatives to the proposed action and analyzes the noaction alternative wherein the Atlas pulse power machine would remain in Los Alamos, New Mexico and continue to be operated at the LANL site.
