Nuclear Watch Interactive Map – U.S. Nuclear Weapons Complex

Two conflicting developments arose this month in US efforts to produce new plutonium pits for its nuclear weapons: The National Nuclear Security Administration (NNSA) announced it had produced a warhead-ready pit—the explosive core of a nuclear weapon—for the first time in decades, and a federal court ruled that NNSA will be required to consider the cumulative environmental and health impacts of its pit production program.

Overshadowing these events is a vigorous debate over the necessity for new pits at all. Previous analyses have found that plutonium pits have viable lifespans well beyond the expected service life of the current stockpile, whereas production of pits for new weapons is part of a sweeping US nuclear modernization that raises concern over the future of arms control and any possibility for stockpile reductions at a time of deteriorating international relations.

U.S. energy officials illegally neglected to study impacts to the environment in efforts to increase plutonium production for nuclear weapons in New Mexico and South Carolina, a federal judge has ruled.

South Carolina District Court Judge Mary Geiger Lewis sided with environmental, anti-nuclear proliferation and community groups last week who sued the National Nuclear Security Administration (NNSA), which oversees the nuclear weapons stockpile as part of the U.S. Department of Energy.

The U.S. is investing billions into restarting the manufacture of plutonium “pits,” the grapefruit-sized spheres developed for nuclear weapons. The federal government halted its manufacturing program at the Rocky Flats Plant in Colorado in 1989 after an FBI raid due to safety concerns and environmental crimes.

The stated goal has been to produce 80 pits per year starting in 2030, split between Savannah River facility proposed in South Carolina and at Los Alamos National Laboratory in New Mexico. The project has faced safety concerns and delays. The Government Accountability Office, a federal watchdog agency, found the NNSA had no comprehensive timeline or cost estimate for pit production, but estimates it’s in the tens of billions of dollars.

Community, environment and anti-nuclear groups brought the lawsuit in 2021, alleging that the NNSA failed to consider alternatives to its two-site proposal and violated the law by not reviewing or changing its last analysis from 2008, when it approved the decisions to move forward in 2020.

A federal judge ruled this week that some nuclear weapons sites in the U.S. do violate environmental regulations.

On Thursday, a federal judge ruled that the National Nuclear Security Administration violated environmental regulations by failing to adequately assess the environmental impact of its plan to expand plutonium pit production at facilities in South Carolina and New Mexico.

The case involves a lawsuit that targeted a 2018 plan to establish two plutonium pit production sites—one at South Carolina’s Savannah River and the other at Los Alamos National Laboratory in New Mexico. Plaintiffs argued the plan was based on an outdated environmental impact study, which failed to properly assess the implications of simultaneous production at both locations. They also insisted the plan weakened safety and accountability measures for the multibillion-dollar nuclear weapons program and its associated waste disposal.

In the ruling on Thursday, Judge Mary Geiger Lewis said, “Defendants neglected to properly consider the combined effects of their two-site strategy and have failed to convince the court they gave thought to how those effects would affect the environment.”

In what advocates called a major win for frontline communities and the rule of law, a U.S. district court judge ruled on Monday that the federal government could not move forward with producing plutonium pits—”the heart and trigger of a nuclear bomb“—at two proposed sites in New Mexico and South Carolina.

Instead, Judge Mary Geiger Lewis agreed with a coalition of nonprofit community groups that the Department of Energy (DOE) and the National Nuclear Security Administration (NNSA) violated the National Environmental Policy Act (NEPA) by failing to fully consider alternatives to producing the pits at New Mexico’s Los Alamos National Laboratory and South Carolina’s Savannah River Site (SRS). Now, the federal government must conduct a full environmental impact statement of how pit production would work at sites across the U.S.

“This is a significant victory that will ensure NEPA’s goal of public participation is satisfied,” attorney for the plaintiffs Ben Cunningham, of the South Carolina Environmental Law Project, said in a statement. “Public scrutiny is especially important because the activities at issue here, by their very nature, result in the production of dangerous weapons and extensive amounts of toxic and radioactive waste. I hope the public will seize the upcoming opportunity to review and comment on the federal agencies’ assessment.”
