National Nuclear Security Agency confirms 152 furloughed at offices in Albuquerque, Los Alamos

Only 14 employees remain at the two sites By: Danielle Prokop-October 22, 2025

The federal government this week sent home more than 150 federal New Mexico employees charged with overseeing national laboratories’ nuclear weapons work, with only 14 employees across two sites remaining at work, the National Nuclear Security Agency confirmed to Source NM.

The furloughs include 71 employees at NNSA’s Los Alamos field office and 81 at the Sandia National Laboratories location, NNSA Deputy Director of Communications Laynee Buckels told Source NM in an email. Seven employees remain at each site, working without pay, she said.

The field offices are responsible for “ensuring compliance with federal contracts to manage and operate the national security assets,” according to the NNSA website

To date there doesn’t appear to be furloughs at LANL, whose employees technically work for a contractor rather than the federal government. Congress is not furloughed, but Speaker Mike Johnson has kept the House out of session. As a result, legislation has come to a screeching halt.

NukeWatch in DC Lobbying for Nuclear Disarmament and Non-Proliferation

Your Nuclear Watch New Mexico team has just returned from a weeklong trip to Washington D.C. (we went so you don’t have to!). The Alliance for Nuclear Accountability (ANA) hosts an annual “DC Days” conference and following Spring Meeting, and we proudly joined as part of a record number of groups this year. Over 60 individuals from 30+ organizations journeyed to DC to lobby congress on nuclear weapons, energy, and waste policy on behalf of the frontline nuclear communities we represent. Members were present from groups representing the entire U.S. nuclear complex, including sites in Georgia, New Mexico, Tennessee, California, Missouri, Colorado, Idaho, Nevada and beyond. NukeWatch NM brought all three staff members—Jay Coghlan, Scott Kovac, and Sophia Stroud (whose participation was made possible by a youth scholarship from ANA)—to participate in DC Days and the subsequent two-day spring meeting. The ANA DC Days schedule included over 70 meetings with senators, representatives, and other relevant agencies, such as the Department of Energy, the Government Accountability Office, and the Defense Nuclear Facilities Safety Board. Our NukeWatch team attended nearly 30 of these meetings. The Alliance for Nuclear Accountability put together a new report to present our “asks” to congress as a coalition, including analysis and recommendations for nuclear weapons, nuclear waste, and nuclear energy policy and funding. Please click HERE for the full report, and HERE for a short summary.

I was glad to see increased representation from Nevada this year, and especially Indigenous representation. In light of the current administration’s attacks on Environmental Justice, it is more important than ever that ANA as a whole, as well as individual member groups, continue to prioritize uplifting Native American voices, not only because of their deep cultural, spiritual, and social connections to the land, including sacred sites and traditional knowledge essential to religious freedom and access, but also because of the violent legacy and ongoing reality of nuclear colonialism, in which Indigenous lands and peoples have been deliberately and disproportionately targeted in the nuclear industry with uranium mining, nuclear weapons testing and production, and the disposal of radioactive waste.

DNFSB Recommendation February 8, 2024 – Excerpts Pertaining to LANL

DNFSB Recommendation 2003-01

Onsite Transportation Safety

[TSD = “Transportation Safety Document”

MAR = “Materials at Risk”, typically plutonium]

Page 2: however, more work is necessary to ensure the LANL TSD appropriately identifies all hazards, analyzes all pertinent accident scenarios, and evaluates the effectiveness of all credited safety controls.

3: the risk remains that LANL or other defense nuclear sites may regress to inadequate TSDs that fail to provide an effective set of safety controls

4: These safety issues are particularly concerning given the high material-at-risk (MAR) allowed by the TSD, the proximity of LANL’s onsite transportation routes to the public, and the nature of several credible accident scenarios. These factors result in high calculated unmitigated dose consequences to the public without an adequate safety control strategy.

DOE Repeatedly Asks Safety Board for Time Extensions, Los Alamos Lab Asked for >150 Cleanup Milestone Extensions, But During Pandemic NNSA Rejects NM Senators’ Request for Extension of Public Comment on Plutonium Bomb Core Production

Lisa Gordon-Hagerty, head of the National Nuclear Security Administration (NNSA), has rejected a request by New Mexico Senators Tom Udall and Martin Heinrich to extend the public comment period on expanded plutonium “pit” bomb core production because of the COVID-19 pandemic. In contrast, even in normal times NNSA and its parent Department of Energy routinely ask other government agencies for major time extensions when it comes to cleanup and independent oversight.

The two Senators requested a 45 day comment period extension on behalf of more than 120 organizations and individuals. Before that, Tom Udall and Martin Heinrich were among 24 Senators who asked the Office of Management and Budget to extend all federal public comment periods during the coronavirus national emergency.

LANL Plans to Release Up To ~100,000 Curies of Radioactive Gas

Santa Fe, NM – On March 11, the Los Alamos National Laboratory (LANL) sent the federal Environmental Protection Agency a formal notice that the Lab will intentionally release up to some 100,000 curies of tritium, a radioactive isotope of hydrogen gas, beginning April 17, 2020.

An internal Lab document states that actual “anticipated emissions” could be half that because of tritium remaining behind in equipment but offers no documentation to substantiate it. During the 1980’s LANL arbitrarily used a self-declared “building shielding factor” not approved by the EPA that reduced its legally required annual calculated radioactive air dose to the public by a third. When that reduction was disallowed LANL was in fact in legal violation of the Clean Air Act. With that as an example, undocumented reductions in radioactive doses claimed by LANL should be viewed with suspicion.

Proposed New Exhaust at WIPP Designed to Release Radiation

19 seconds – the amount of time airborne radiological contamination could be released before the safety dampers close. This assumes that all other components work perfectly.

A recent report from the Defense Nuclear Facilities Safety Board (DNFSB) explains the DNFSB’s calculations on the proposed new (estimated at nearly $300 million) safety significant confinement ventilation system (SSCVS).

Faulty Radioactive Liquid Waste Valves Raise Crucial Plutonium Pit Production and Safety Board Issues

Scott KovacMay 31, 2019June 3, 2019DNFSB, DOE, Modernization, Pit Production, Plutonium, Plutonium Pit Production

There should be no expanded pit production until nuclear safety is fully assured by an independent, unrestricted Safety Board, and our congressional delegation should be the first to demand that.

WIPP Receives Notice of Upcoming Investigation for Chemical Overexposures to Workers

Scott KovacFebruary 1, 2019October 21, 2025DNFSB, Nuclear Safety, Nuclear Waste, WIPP

On January 29, 2019, DOE’s Office of Enterprise Assessments notified Nuclear Waste Partnership, LLC (NWP), the managing and operating contractor for the Waste Isolation Pilot Plan (WIPP), of its intent to investigate heat stress-related events and chemical exposures at WIPP. The events, occurring from July through October 2018, include multiple overexposures to hazardous chemicals, including carbon tetrachloride, nitrogen dioxide, and sulfur dioxide, as well as a series of heat-stress incidents.

Los Alamos Cleanup At the Crossroads: Treat All Los Alamos Lab Radioactive Wastes Consistently

Los Alamos Cleanup At the Crossroads:

Treat All Los Alamos Lab Radioactive Wastes Consistently

The Defense Nuclear Facilities Safety Board’s role and responsibility includes gathering information regarding the hazards to the public and workers posed by the management of transuranic (TRU) wastes at Los Alamos National Laboratory (LANL), as well as the Department of Energy’s (DOE) plans to address those hazards. The Board will examine DOE’s actions taken or inadequacies addressed in the current safety policies of the various facilities that manage or store TRU wastes at LANL. The Board is also interested in understanding actions taken to improve TRU waste management at LANL after the improper handling and treatment of TRU wastes that resulted in a ruptured barrel that shut down the Waste Isolation Pilot Plant (WIPP).
