ALAMOS, NM – The
National Nuclear Security Administration (NNSA) has issued an Amended Record of
Decision (ROD) concerning the Nuclear Facility portion of the Chemistry and
Metallurgy Research Replacement project (CMRR-NF).
Following a supplemental environmental impact
analysis and public input process, NNSA has selected the Modified CMRR-NF Alternative
described in the Final Supplemental Environmental Impact Statement (SEIS) to
proceed forward with the design and construction of the nuclear facility at Los
Alamos National Laboratory.
As described in the final SEIS,
the facility will be constructed at Technical Area 55 and co-located with the
other component of the Chemistry and Metallurgy Research Replacement project - the
recently completed Radiological Laboratory/Utilities/Office Building (RLUOB).
RLUOB was constructed directly east of the prospective CMRR-NF site consistent
with the 2004 ROD.
NNSA has incorporated updated
seismic safety design information into development of the Modified CMRR-NF
design that is described in the final SEIS. Two construction options were considered and
analyzed under this alternative: the Deep Excavation Option and the Shallow
Excavation Option. NNSA will select the appropriate Excavation Option for
implementing the construction of this building after initiating final design
activities, when additional geotechnical and structural design calculations and
more detailed engineering analysis will be performed to support completing the
and RLOUB will replace the 60-year-old Chemistry and Metallurgy Research Building
and consolidate existing research capabilities at LANL to ensure continuous
support of NNSA stockpile stewardship and strategic objectives. The new
facility will provide labs for analytical chemistry, materials characterization
and actinide research and development activities that not only support the
safety, security, and reliability of existing nuclear weapons but also benefit
nonproliferation, fundamental physics, basic science, medical isotopes, and
technology development for waste treatment and minimization.

by Congress in 2000, NNSA is a semi-autonomous agency within the U.S.
Department of Energy responsible for enhancing national security through the
military application of nuclear science in the nation’s national security
enterprise. NNSA maintains and enhances the safety, security, reliability, and
performance of the U.S. nuclear weapons stockpile without nuclear testing;
reduces the global danger from weapons of mass destruction; provides the U.S.
Navy with safe and effective nuclear propulsion; and responds to nuclear and
radiological emergencies in the U.S. and abroad. Visit http://www.nnsa.energy.gov/ for more information.
