Hot Plutonium Pit Bomb Redux

Last week U.S. District Judge Mary Lewis Geiger, South Carolina, faulted the Department of Energy and the National Nuclear Security Agency for ignoring the National Environmental Protection Act and rushing plans to fabricate plutonium pit bombs at Savannah River Site, near Aiken, South Carolina.

Newly designed plutonium pits will serve as “triggers” for the next generation of nuclear warheads mounted atop Sentinel, the next generation of intercontinental ballistic missile, and for new submarine-launched nuclear weapons. Combined, these projects comprise major components in the trillion-dollar “modernization” of the U.S.  strategic deterrence force.

Plaintiffs including Savannah River Site Watch, South Carolina Environmental Law Project Gullah/Geechee Sea Island Coalition, Nuclear Watch New Mexico and Tri-Valley CAREs forced NNSA to halt construction on many phases of its plutonium pit facility near Aiken, SC, to hold public scoping meetings, solicit public comments, and produce a Programmatic Environmental Impact Statement within thirty months.

Plaintiffs successfully argued that the plutonium pit modernization project was complex, involving diverse entities, was spread over wide geographical regions and therefore, by definition, required a “programmatic environmental impact statement, PEIS.

The proposed plutonium pit facility at Savannah River Site will reconstruct a massive 500-room partially completely abandoned building designed for the Mixed Oxide Plant. The spectacularly failed MOX plant would have processed old plutonium pits from de-commissioned US nuclear weapons per a nuclear weapons agreement with the Russians in 2000. Poor management and engineering revisions multiplied costs exceeding $7 billion when DOE finally terminated the MOX project in 2019. DOE recently paid the State of South Carolina an extra $600 million fine for failure to remove 10 tons of plutonium delivered to the MOX plant and stored at SRS. Ironically SRS is importing a different 10 tons of plutonium pits from the PANTEX pit storage site in Texas to manufacture new pits.

NNSA’s plan for plutonium pit production at Savannah River Site involves complex coordination between Los Alamos, the Waste Isolation Pilot Plant in Carlsbad NM, the Lawrence Livermore National Laboratory in CA and the Kansas City National Security Campus, and therefor requires a NEPA “programmatic environmental impact statement”. NNSA refused repeated calls to perform the PEIS, which resulted in the successful lawsuit agreed last week.

NNSA has yet to satisfy Government Accounting Office best practice guidelines for the SRS pit project. GAO’s repeated calls for NNSA to create quality Integrated Master Schedules and Life Cycle Cost Estimates for its plutonium pit modernization program remain unfulfilled. These plans and guidelines establish best practices for building an efficient cost-effective project, something MOX consistently ignored, leading to its disastrous failure. Congress subsequently ordered NNSA meet these GAO parameters by July 2025.

Congress had mandated in 2019 that Los Alamos National Laboratory in New Mexico manufacture 80 plutonium pits per year by 2030.  Because LANL is a research facility, it has not produced any plutonium pits since 2011, and never at scale. It was unprepared to fulfill this Congressional mandate, authored by Senator John McCain. In response, NNSA then divided the plutonium pit project in two: Savannah River Site would produce 50 pits per year by 2030, and LANL 30 pits. SRS has never manufactured plutonium pits, though it did produce 10 tons of plutonium for pit fabrication at Rocky Flats, CO beginning in 1957. Thirty million gallons of highly radioactive wastes from that project, more than 200 million curies* of radiation, remain stored on- site at SRS, making it one of the most radioactive Superfund sites in the U.S.

Rocky Flats had produced one to two thousand plutonium pits per year for decades until it was closed in 1989. After whistleblower leaks, (see Jon Lipsky, James Stone) the FBI and EPA raided Rocky Flats discovering gross fraud and egregious violations of environmental regulations by contractor, Rockwell International. Rocky Flats was closed and will remain a superfund site into the far distant future.

Parts of Los Alamos National Lab, wedged on a tabletop mesa, comprises a superfund site with residual plutonium still found around the site and in surrounding canyons from operations and waste dumping begun in the 1940’s “Oppenheimer years”.

DOE recently signed a consent decree with the State of New Mexico to assume greater responsibility for the clean-up of waste deposit wells and trenches that threaten nearby towns like White Rock, the San Ildefonso Pueblo and the Rio Grande River with radiological contamination. DOE paid New Mexico a $420,000 fine for mishandling hazardous wastes is 2024.

LANL itself has experienced numerous and serious safety accidents, including a plutonium fire, flooding, glove box contamination and a plutonium “criticality” accident, in recent years. The most recent 2023 safety report for LANL, operated by Triad LLC, showed improvement in its safety operations, though in that same year LANL was fined $420,000 by New Mexico for improper handling of hazardous materials.

Plutonium, Pu, is a man-made metallic element. It is highly toxic, highly radioactive, pyrophoric, (spontaneously ignites on contact with air) and fissionable. It is extremely challenging to produce, purify, mill, melt, mold, weld, control and store. All these processes have taken place at sites across the U.S. since the 1940’s and are now catalogued by DOE as “legacy hazardous waste sites”.

Because plutonium ignites on contact with air, it must be handled in “glove boxes”, self-contained hermetically sealed boxed filled with inert gases. Impervious rubber sleeves extend into the box, and workers slip their arms into these sleeves, then manipulate the plutonium through different phases of pit production. Any nicks or cracks in the rubber gloves can and have resulted in plutonium leaks, and serious illnesses.

Glove boxes and gloves for the plutonium pit project, in example, are already is short supply, demonstrating how integral and integrated every aspect of the plutonium pits program is, and how poor planning could disrupt the program; the basic tenant of the lawsuit against NNSA.

Training a skilled glove box worker at LANL can take four years. A shortage of skilled workers at LANL poses a regular challenge, one that will intensify as LANL workers will also train unskilled SRS workers. A shortage of workers at WIPP in Carlsbad NM has been a chronic problem despite significant wage increases from DOE.

Historically, sites involved with the production, refining, milling or fabrication of plutonium or plutonium pits for nuclear weapons have left a voluminous legacy of radionuclide pollution. Radioactive wastes generated in weapons production beginning with the 1940’s Manhattan Project, by statute, are destined for the Waste Isolation Pilot Plant, WIPP, in Carlsbad, New Mexico. Because plutonium has a half life of 24,000 years and remains lethal for much longer, plutonium waste products trucked over millions of highway miles to WIPP are stored in vaults excavated into salt domes 2000 feet underground. While WIPP is the sole repository for defense department transuranic wastes, the Government Accounting Office cautioned that WIPP may not have the capacity to accept all the plutonium pit wastes generated at LALN and SRS. Timely removal of plutonium waste from SRS and LANL is crucial for uninterrupted pit production.

A fire in WIPP’s salt dome closed the facility for 3 years in 2014.  A fire at LANL closed its operation for 3 years in 2013.

Both SRS and LANL will recycle surplus plutonium pits from the strategic reserve at PANTEX near Amarillo, TX. Currently 4000 reserve pits and 10,000 surplus pits waiting disposal are stored at PANTEX. Re-engineered pits from SRS and LANL will be returned to PANTEX for final assembly into W87-1 and W 88 nuclear warheads.

The rate of deterioration of plutonium pits, 30 or more years old, has concerned and motivated lawmakers to legislate a complete replacement of all 3,600 deployed and reserve nuclear warheads. Independent scientific groups like JASON and the Livermore National Lab have estimated that plutonium pits maintain their viability for 100 or even 150 years. Hardware within the nuclear warhead corrodes much more quickly than the pits themselves, focusing doubt on the race to replace the pits themselves.

The programmatic environmental statement ordered by federal Judge Geiger may resolve many questions posed by the rush to produce new plutonium pits. The pits produced at SRS and LANL will trigger new W87-1 nuclear warheads. What need is there for a new warhead when the old W87-0 has the same safety features? Why are SRS and LANL adopting an aggressive production schedule when the new Sentinel ICBM deliver systems is way over budget and at least a decade away from deployment?  Why does the production of new plutonium pits take priority over cleaning up the hazardous legacy of previous pit production? Has any plutonium production site ever not become a hazardous waste site?    Will NNSA slow pit production to engineer safety improvements instead of placing workers in risky dangerous situations? Do we really want to spend a trillion dollars and start a new nuclear arms race?
