Amended Record of Decision for the Nuclear Facility Portion of the Chemistry and Metallurgy Research Building Replacement Project at Los Alamos National Laboratory, Los Alamos, NM

Résumé

The National Nuclear Security Administration (NNSA) of the U.S. Department of Energy (DOE) is issuing this Amended Record of Decision (AROD) for the Nuclear Facility portion of the Chemistry and Metallurgy Research Building Replacement (CMRR) Project at the Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico. After completing an EIS, NNSA issued a ROD for the CMRR Project on February 3, 2004, deciding to construct a two-building, partially above-ground, CMRR Facility in Technical Area-55 (TA-55) at LANL. This new facility would replace the aging 60-year-old Chemistry and Metallurgy Research (CMR) Building at LANL, and would ensure the ability to continue to perform analytical chemistry and materials characterization operations using plutonium and other actinides in a safe, secure manner in support of NNSA mission activities. As the CMRR Project planning and design process has progressed over the past 8 years, the first building of the two-building CMRR Facility (the Radiological Laboratory/Utility/Office Building, also known as the RLUOB) has been constructed. During this same time period, primarily as a result of efforts to better understand the seismic environment at
