The Department of Energy (DOE) completed an Environmental Impact Statement analysis in 2004 for a new project at the Los Alamos National Laboratory. This project, called the Chemistry and Metallurgy Research Replacement (CMRR) is a huge new plutonium pit facility for expanded nuclear weapons production.
As proposed, the CMRR project will cost close to $6 billion, a 1,000% increase over initial cost estimates. Beyond this, the DOE now recognizes that there is a greater risk of damage to such a facility from earthquakes. Both of these facts have caused enough pressure for the NNSA to conduct a Supplemental Environmental Impact Statement (SEIS) for this project.
