U.S. Nuclear Agency Releases Environmental Impact Statement, a “Legal Fig Leaf” for Plutonium Pit Program Decisions

In 2018, the NNSA announced plans to seek to produce a total of 80 plutonium pits per year at two locations: the Savannah River Site in South Carolina (50 pits) and Los Alamos Nuclear Laboratory in New Mexico (30 pits). This would be the first large scale production of pits since the heights of the Cold War. Following a lawsuit from a coalition of community and nuclear safety advocates, a court ruling in 2024 found that the NNSA had "neglected to properly consider the combined effects of their two-site strategy," and a legal settlement required the agency to conduct a PEIS and outlined the ways it must engage with the public.

Far from considering all the environmental and health impacts of plutonium pit production across the U.S. nuclear complex, the NNSA's draft PEIS focuses on two production sites, with only passing acknowledgement of the increased impacts at other sites, including nationwide transportation and impending waste management bottlenecks, according to the Union of Concerned Scientists (UCS).

"It's disappointing to see the NNSA pushing out a legal fig leaf, with what amounts to a belated justification for decisions taken years before, which violates the intent and purpose of such analyses under the National Environmental Policy Act," said Dr. Dylan Spaulding, a senior scientist in the Global Security Program at UCS. "Cost and schedule should factor into the final decisions that result from the PEIS, but the NNSA has already been acting on foregone decisions for nearly eight years."

Despite lacking this environmental impact statement and concerns over cost and schedule overruns, the agency has been rapidly pursuing its expansion plans. News emerged recently that NNSA is already doubling the quota for pits at Los Alamos to 60 a year, beyond what was analyzed in a site-wide environmental impact statement released just two weeks ago. The pit production program has cost tens of billions of dollars in recent years and the FY27 budget ramps up the program budget by roughly 80%.

The draft PEIS clearly highlights an increased risk of radiation in the environment and across communities near facilities and workers. The NNSA attempts to write these off as negligible increases and selects the most harmful and risky option of continued multi-site operations.

"No community should be forced to bear the health burdens of a costly and technically unnecessary expansion of the United States' international threat of nuclear war white-washed as 'nuclear deterrence'-especially the people already residing near nuclear facilities and transportation routes," said Dr. C.A. Forté, a scientist in the Global Security Program at UCS. "Frontline communities in New Mexico, South Carolina, Georgia, and elsewhere still face real consequences from past radiation exposures and ongoing lack of contamination remediation due to U.S. government negligence."

A UCS analysis found that the United States does not need new pits to maintain its nuclear arsenal at the present time, that program costs could balloon to exorbitant levels, and that renewed production at elevated levels could put workers and communities in real danger of further radiation exposure-without a clear outline of the environmental burdens these communities already face. The United States has over 15,000 pits currently in reserve, thousands of which are suitable for reuse.

"The NNSA failed to fully consider viable alternatives to new pit production, including available avenues for reuse of existing pits," said Dr. Spaulding. "Instead, they claim their hands are tied by existing legal directives rather than responding to very real technical, logistical, and fiscal realities that plague the current program."
