The LANL Director mentioned Non-proliferation is a big part of their work. However, the Nuclear Nonproliferation program budget is a mere 6.5% of the total Lab budget (Nuclear Weapons is 84%, with a Billion dollar increase for FY26). https://nukewatch.org/wp-content/uploads/2025/09/FY26-Lab-Table-spreadsheets-Chart-1.pdf Nuclear Nonproliferation is a valuable program that LANL does well, and its funding should not be cut to provide more money for nuclear weapons production (literally the opposite of nonproliferation). The Nuclear Nonproliferation budget should be increased, especially if the Lab director agrees on its importance. NukeWatch NM is entirely supportive of LANL’s Sealed Sources program, which serves as the nation’s lead for collecting potentially dangerous radioactive materials that are no longer needed, securing them, and ensuring they don’t fall into the wrong hands, protecting communities and enhancing security.

On the discussion of AI missions at the lab:

The lab is partnering with NVIDIA for their hardware and ChatGPT/Open AI for their models. “The goal is to harness the power of the next evolution of high performance computing and apply it to our national security science and technology. Big development on this front is the “genesis” mission…” and in an answer to a question, want to “use artificial intelligence to [for example] help us develop the molecules that could deliver a therapeutic isotope to a cancer cell with high specificity so that when that undergoes radioactive decay the decay products basically kill the cancer cell but no surrounding tissue”

Again, the lab’s nuclear weapons budget ate up almost all else this year – how does the lab propose to work on this kind of work when its’ science budget is less than 1%? How will this advancement of AI be applied to our national security science and technology in terms of nuclear weapons? NukeWatch has serious concerns and questions regarding the tangible risks associated with integrating commercial AI infrastructure to be with active national security and nuclear defense programs. Beyond this, a $1.25 billion advanced computing campus is planned in Michigan to support far-away Los Alamos Lab in high-performance computing and AI research.

Planned Nuclear Weapons Activities Increase to 84% of Lab’s Budget; All Other Programs Cut

Sophia MerynBudget, Climate Change, DOE, LANL Cleanup, Los Alamos Nat'l Lab., NNSA, Nuclear Waste, Nuclear Weapons, Pit Production at LANL

The Department of Energy and Los Alamos National Laboratory have released the LANL congressional budget request for the upcoming fiscal year, 2026, which begins on October 1, 2025. The request shows a continued major increase and expansion of the plutonium pit production program (plutonium pits are the triggers of nuclear weapons). LANL is frantically trying to increase its capabilities to begin making 30 pits per year by 2028.

NukeWatch created the attached chart to give a visual of how taxpayer dollars are annually spent at the Lab. LANL’s FY 2026 total budget request is $6 billion, which is a 17% increase over the FY 2025 $5.2 billion total budget. This includes a 24% increase in the nuclear weapons budget over FY 2025.

AIKEN, S.C. — Today the National Nuclear Security Administration (NNSA), the semi-autonomous nuclear weapons agency within the Department of Energy, published a formal Notice of Intent in the Federal Register to complete a nationwide “programmatic environmental impact statement” on the expanded production of plutonium “pit” bomb cores. Pits are the essential radioactive triggers of modern nuclear weapons. The NNSA is aggressively seeking their expanded production for new-design nuclear weapons for the new nuclear arms race.

The South Carolina Environmental Law Project (SCELP) successfully represented the Gullah/Geechee Sea Island Coalition and Nuclear Watch New Mexico, Savannah River Site Watch and Tri-Valley Communities Against a Radioactive Environment in a legal challenge to NNSA’s attempt to improperly jump start dual site pit production. On September 30, 2024, United States District Court Judge Mary Geiger Lewis ruled that the NNSA had violated the National Environmental Policy Act (NEPA) by failing to properly consider alternatives before proceeding with its plan to produce at least 30 pits per year at the Los Alamos National Laboratory (LANL) in New Mexico and at least 50 pits per year at the Savannah River Site (SRS) in South Carolina.

Nonprofit public interest groups have reached an historic settlement agreement with the Department of Energy’s semi-autonomous nuclear weapons agency, the National Nuclear Security Administration (NNSA). This is the successful result of a lawsuit against NNSA over its failure to complete a programmatic environmental impact statement on the expanded production of plutonium “pit” bomb cores, as required by the National Environmental Policy Act (NEPA). This agreement and a joint motion to dismiss have been submitted to Judge Mary Lewis Geiger of the Federal District of South Carolina. Should the Court enter the dismissal and retain jurisdiction to enforce the settlement, the agreement will go into effect.

This lawsuit was first filed in June 2021 by co-plaintiffs Savannah River Site Watch of Columbia, SC; Nuclear Watch New Mexico of Santa Fe, NM; Tri-Valley Communities Against a Radioactive Environment (CAREs), based in Livermore, CA; and the Gullah/Geechee Sea Island Coalition of coastal Georgia. NNSA promptly moved to have the case dismissed which in February 2023 Judge Lewis rejected, calling her decision “not a close call.”

In September 2024, Judge Lewis ruled that DOE and NNSA had violated NEPA by failing to properly consider alternatives before proceeding with their plan to produce plutonium pits, a critical component of nuclear weapons, at the Los Alamos National Laboratory (LANL) in New Mexico and, for the first time ever, at the Savannah River Site (SRS) in South Carolina. The Court found that the plan’s purpose had fundamentally changed from NNSA’s earlier analyses which had not considered simultaneous pit production at two sites. Judge Lewis directed the Defendants and Plaintiffs to prepare a joint proposal for an appropriate remedy which fostered additional negotiations.

New Draft LANL Site-Wide Environmental Impact Statement is Released

Sophia MerynLos Alamos Nat'l Lab., NEPA, Nuclear Policy, Nuclear Waste, Pit Production, Pit Production at LANL, Plutonium Pit Production

NNSA’s Preferred Future for the Lab is Radically Expanded Nuclear Weapons Programs

The National Nuclear Security Administration (NNSA) has finally released its Draft Site-Wide Environmental Impact Statement (SWEIS) for Continued Operation of the Los Alamos National Laboratory. This is more than two years after it was first announced and sixteen years after the last site-wide EIS. During that time the Lab has become more and more a nuclear weapons production site for the new global nuclear arms race. Accordingly, the central point of the new draft LANL SWEIS is “NNSA has identified the Expanded Operations Alternative as the preferred alternative for the continuing operations of LANL.” Draft LANL SWEIS, page S-13.

As policy background, the draft LANL SWEIS pays lip service to the 1970 NonProliferation Treaty (NPT):

“In Article VI of the NPT, treaty parties “undertake to pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament…” The U.S. takes this commitment seriously and has emphasized dedication to both the long-term goal of eliminating nuclear weapons and the requirement that the U.S. has modern, flexible, and resilient nuclear capabilities that are safe and secure, until such a time as nuclear weapons can prudently be eliminated from the world.” P. 1-7.

Left unsaid is that no nuclear power, including the United States, has ever even tried to enter into good faith negotiations toward nuclear weapons disarmament, pledged to more than a half-century ago. Instead, all nuclear weapons states are now engaged in massive “modernization” programs to keep nuclear weapons forever, leading to today’s accelerating nuclear weapons arms race. Also, very much left unsaid is the Treaty on the Prohibition of Nuclear Weapons, ratified by 73 countries, nearing its fourth anniversary since it went into effect.

Court Rules U.S. Nuclear Weapons Production Plan Violates Federal Law

Sophia MerynDOE, Environmental Impact, Los Alamos Nat'l Lab., NEPA, New Mexico, Nuclear Weapons, Pit Production, Pit Production at LANL, Pit Production at SRS, Plutonium Pit Production

On September 30, United States District Court Judge Mary Geiger Lewis ruled that the United States Department of Energy (“DOE”) and its semi-autonomous nuclear weapons agency, the National Nuclear Security Administration (“NNSA”), violated the National Environmental Policy Act (“NEPA”) by failing to properly consider alternatives before proceeding with their plan to produce plutonium pits, a critical component of nuclear weapons, at the Los Alamos National Laboratory (“LANL”) in New Mexico and, for the first time ever, at the Savannah River Site (“SRS”) in South Carolina.

The Court found that the plan’s purpose had fundamentally changed from NNSA’s earlier analyses which had not considered simultaneous pit production at two sites.  These changes necessitated a reevaluation of alternatives, including site alternatives, which Defendants failed to undertake prior to moving forward while spending tens of billions of taxpayers’ dollars. Therefore, the Court entered judgment in favor of Plaintiffs, the nonprofit public interest groups Savannah River Site Watch, Nuclear Water New Mexico and Tri-Valley Communities Against a Radioactive Environment (CAREs); the Gullah/Geechee Sea Island Coalition; and Tom Clements as an individual plaintiff.

As a result of this ruling, the Defendants are required to newly assess pit production at a nation-wide programmatic level which will mean undertaking a thorough analysis of the impacts of pit production at DOE sites throughout the United States, including radioactive waste generation and disposal. Under the National Environmental Policy Act (NEPA), this will provide the opportunity for public scrutiny of and formal comment on their assessments.

NNSA Town Hall July 22nd – Hruby: “We have to limit the growth of Los Alamos Laboratory…”

The U.S. Department of Energy (DOE) Office of Environmental Management (EM) Los Alamos Field Office held a Town Hall event hosted by the DOE National Nuclear Security Administration (NNSA) and EM on Monday, July 22, in Santa Fe. The Town Hall was led by NNSA’s Jill Hruby and EM’s Senior Advisor Candice Robertson. The intent according the event flier was to “engage with the community, provide updates, and address concerns related to the DOE’s activities and initiatives.”

The public comment period began with Jay Coghlan, executive director of NukeWatch NM, reading aloud a statement from Archbishop John C. Wester to the DOE, NNSA and EM.

“Nuclear disarmament is a right to life issue. No other issue can cause the immediate collapse of civilization. In January 2022 I wrote a pastoral letter in which I traced the Vatican’s evolution from its uneasy conditional acceptance of so-called deterrence to Pope Francis’ declaration that the very possession of nuclear weapons is immoral.  https://archdiosf.org/living-in-the-light-of-christs-peace “Therefore, what does this say about expanded plutonium pit production at the Los Alamos Lab? And what does it say about the obscene amounts of money that are being thrown at pit production, often excused as job creation?

“What does this say about the fact that the [NNSA] is pursuing expanded pit production without providing the public the opportunity to review and comment as required by the National Environmental Policy Act? I specifically call upon NNSA to complete a new LANL Site-Wide Environmental Impact Statement.

“I have a simple message for NNSA and the nuclear weapons labs. You’re very good at creating them. Now show us how smart you are by demonstrating how to get rid of nuclear weapons. Stop this new arms race that threatens all of civilization. Let’s preserve humanity’s potential to manifest God’s divine love toward all beings.

READ FULL STATEMENT

NNSA adminstrator Jill Hruby began the event with a spiel about Russia continuing their nuclear saber rattling and China aquiring over 1500 nuclear weapons by 2025. She said NNSA is putting the pressure on to develop 7 weapons

Jill Hruby intro:

A lot has changed in the last 15 months. At the highest level Russia continues its full scale invasion of Ukraine including nuclear Saber rattling and the takeover of the Zaporizhia nuclear power plant. It has violated most nuclear norms and most recently seems to be exploring using nuclear weapons in space. China is projected to have 1500 nuclear warheads by the year 2035 and continue to express an intent to take over Taiwan, their technology advancement is significant, and the combination of China and Russia now means that parity in the number of nuclear weapons doesn’t make any sense. In addition, we have North Korea and Iran that are still players in this world and the cooperation between all of them is also advancing. But what I want to say is despite these advances, we do not want an arms race, this administration doesn’t want a new arms race, the NNSA doesn’t want an arms race. We’re trying to exercise leadership and transparency, but we also can’t sit on our hands, and so we’re trying to find the balance.

FEDERAL BUDGET NEWS

Release of federal FY 2025 budget expected March 11 (it will initially be just topline numbers).

Meanwhile on the FY 2024 budget: House and Senate Armed Services Committee authorized funding exceeding Biden’s request, including money for the Sea-Launched Cruise Missile and nuclear warhead (reminder: that the President doesn’t want), plus adding $$ for plutonium pit production at the Savannah River Site. But appropriations bills are still not happening because of ever increasing congressional dysfunction. This is now best exemplified by Republicans rejecting an immigration bill they initially drafted but that Trump denounced because he wanted immigration to remain a hot issue during the presidential election campaign.

The current second “laddered” Continuing Resolution that is keeping the government running expires March 1 and 8.

As New Mexicans Struggle, Sen. Heinrich is Proud of Nuclear Weapons Money

Sophia MerynBudget, Los Alamos Nat'l Lab., New Mexico, Pit Production at LANL, Plutonium Pit Production, Sandia National Laboratories

Sen. Heinrich is so proud of all of the nuclear weapons money in New Mexico. He is one of the chief congressional architects of expanded production of plutonium “pit” bomb cores and sits on the Senate Energy and Water Appropriations Subcommittee from where he can direct $$billions to the Sandia and Los Alamos Labs.

But during the Department of Energy’s long presence in the Land of Enchantment, according to Census Bureau data New Mexico has slid in per capita income from 32nd in 1959 to 47th in 2022. New Mexico has the most children living in poverty (30%) and is rated dead last in well-being of children and quality of public education. Finally, in a report that the Los Alamos Lab tried to suppress, six county governments surrounding Los Alamos County suffer a net economic loss from LANL.

In fiscal year 2024 DOE will spend $10 billion in New Mexico, 75% for core nuclear weapons research and production programs and 5% for dumping related radioactive wastes in our state. DOE’s budget is 6% greater than the entire operating budget of the State of New Mexico ($9.4 billion).

Senator Heinrich, please explain what good all that nuclear weapons money does for average New Mexicans, and not just for the privileged nuclear weapons enclaves.

Nuclear weapons issues

Final conference by Senate and House Armed Services Committee deleted expansion of the Radiation Exposure Compensation Act that would have covered Trinity Test Downwinders, among others. In contrast, it authorized tens of billions for expanding nuclear weapons programs. So, it’s nothing for those harmed by nuclear weapons testing and production in New Mexico, but radical expansion of those programs that did harm them.

The FY 2024 Defense Authorization Act added money above Biden’s request for pit production at the Savannah River Site and the Sea-Launched Cruise Missile and its new nuclear warhead. The Biden Administration opposed the SLCM, but Congress authorized it anyway.

LANL SWEIS

The 2020 Supplement Analysis that we had robustly critiqued with comprehensive formal comments, which DOE/NNSA have ignored, contains analysis of pit production based solely off the 2008 SWEIS pit analysis. Our single biggest point in the 2020 SA comments was the need for a programmatic environmental impact statement on expanded plutonium pit production.

New bomb: The Pentagon has announced a new nuclear bomb, the B61-13. The B61-12 is now in production and will be forward deployed in Europe. But it has a dial-a-yield that maxes out at 50 kilotons. The new B61-13 will max out at 360 kt to get at hardened deeply buried targets (both have limited earth-penetrating capabilities). At one time, production of the B61-12 at least potentially signified retirement of the 1.2 megaton surface burst B83 strategic bomb, but now production of the B61-13 will probably be relatively quick at the tail end of already scheduled B61-12 production.

Los Alamos Lab’s Future at a Crossroads: Cleanup or More Nuclear Weapons? NukeWatch Applauds NM State Rejection of Fake Cleanup

Sophia MerynDOE, GAO, High-level Radioactive Waste, LANL Cleanup, Los Alamos Nat'l Lab., New Mexico, NMED, Nuclear Waste, Nuclear Weapons, Pit Production at LANL

Santa Fe, NM – In an important win for genuine cleanup at the Los Alamos National Laboratory (LANL), the New Mexico Environment Department (NMED) has rejected the Lab’s plans for so-called cleanup through “cap and cover.” LANL’s plan would leave existing radioactive and toxic wastes uncharacterized and forever buried in unlined pits and trenches as a permanent threat to groundwater. At issue is remediation of the Lab’s “Material Disposal Area C” waste dump that has 7 pits and 108 shafts of radioactive and toxic wastes. Area C is located in the heart of nuclear weapons production at LANL, contiguous to the Lab’s main plutonium facility which is expanding production of plutonium “pit” bomb cores.

In a September 7, 2023 “Public Notice of Statement of Basis,” the Environment Department ruled:

“For maximum protection of human health and the environment and to ensure that the drinking water resource can be conservatively protected, NMED has determined that the selected [cleanup] remedy for MDA C must consist of waste excavation, characterization, and appropriate disposal of the buried waste… Excavation will ensure that the source of contamination at MDA C is removed…”

National Nuclear Security Administration: New Assessments of Major Projects from the Government Accountability Office

Sophia MerynGAO, Pit Production at LANL, Pit Production at SRS, Plutonium Pit Production

National Nuclear Security Administration: Assessments of Major Projects

GAO-23-104402 Published: Aug 17, 2023. Publicly Released: Aug 17, 2023.

The National Nuclear Security Administration plans to invest over $30 billion in its major projects to modernize the research and production infrastructure supporting the nation’s nuclear weapons stockpile. This is our first biennial assessment of NNSA’s major projects.

As of March 2023, NNSA’s major projects collectively exceeded their cost estimates by over $2 billion. They also surpassed their collective schedules by almost 10 years. Cost growth and schedule delays had multiple causes, such as lower levels of worker productivity than planned.

The Department of Energy has been on the Government Accountability Office’s “High Risk List” for project mismanagement since 1991. A January 2023 GAO report says it all: NNSA Does Not Have a Comprehensive Schedule or Cost Estimate for Pit Production Capability. Congress has made its ongoing concern over the lack of pit aging studies explicit in legislation. The FY 2021 Consolidated Appropriations Act enacted the following provision:

“Pit and Plutonium Aging.-There is concern with the apparent lack of focus on advancing knowledge regarding pit and plutonium aging since the JASONs conducted its first study in 2006. Given the future needs of the nation’s nuclear deterrent, a robust program of research and experimentation is needed. Therefore, NNSA is directed to develop a comprehensive, integrated ten-year research program for pit and plutonium aging that represents a consensus program among the national laboratories and federal sponsors. Such a plan shall include estimated cost of ongoing research, new or upgraded capability needs, and key near-, mid-, and long-range milestones. The plan shall be submitted to the Committees on Appropriations of both Houses of Congress not later than 180 days after enactment of this Act.”

As far as is publicly known no such plan has been submitted to Congress despite its statutory requirement. That said, a ten year plan to have plutonium pit aging studies is not sufficient to begin with when uncertainty over pit aging is being used as the rationale for an aggressive plutonium pit production program costing at least $60 billion over the next thirty years. The recent GAO report states, “…Six projects in the design phase are implementing significant changes that may increase their cost and schedule beyond NNSA’s preliminary estimates. These include a project to modify existing plutonium processing facilities at Los Alamos National Laboratory in New Mexico.”

Furthermore, the entire U.S. $2 Trillion “Modernization” plan includes new intercontinental ballistic missiles, new cruise missiles, heavy stealth bombers and
submarines, which entails rebuilding warheads with new military capabilities plus completely new-design nuclear weapons. This is not just for “deterrence” but instead for nuclear warfighting capabilities. No production of plutonium pits is scheduled to maintain the safety and reliability of the existing nuclear stockpile; instead it is for new-design nuclear weapons. The US is inspiring a new arms race with nuclear weapons forever.

Independent Government Accountability Office Releases Scathing Report on Expanding Plutonium Pit Production; Pressure Mounts on Los Alamos Lab to Increase Production

Sophia MerynGAO, Los Alamos Nat'l Lab., MOX, NNSA, Pit Production at LANL, Pit Production at SRS, Plutonium Pit Production, Savannah River Site

Santa Fe, NM – Today, the independent Government Accountability Office (GAO) released a scathing report entitled NNSA Does Not Have a Comprehensive Schedule or Cost Estimate for Pit Production Capability. The National Nuclear Security Administration (NNSA) and its parent Department of Energy have been on the GAO’s High Risk List for project mismanagement since 1991.

Plutonium pits are the essential radioactive cores of nuclear weapons. There has been only limited production at the Los Alamos National Laboratory (LANL) since 1989 when a FBI raid investigating environmental crimes abruptly shut down production at the Rocky Flats Plant near Denver. NNSA now plans to spend $2.9 billion in FY 2023 alone to establish production of at least 30 pits per year at LANL and 50 pits per year at the Savannah River Site (SRS) in South Carolina.

The two main findings of GAO’s report are:

  • NNSA’s Plutonium Pit Production Scope of Work Includes Dozens of Programs, Projects, and Other Activities Managed by Multiple NNSA Offices at Multiple Sites (p 19)

BY JAY COGHLAN

Good article indeed. Kudos to Scott Wyland.

But to add to it:

The National Nuclear Security Administration (NNSA) cannot do, or rather will not do, good governance 101 for its largest program ever (i.e., expanded plutonium pit production), which is credible cost estimates and schedules. Why won’t NNSA do that? Because of PR and political concerns when their flaky cost estimates (such as they are) get blown up by inevitable escalating costs. NNSA knows that if it gave accurate projected costs Congress and the public would balk. Thus, the agency goes in lowballing costs, which always inevitably rise. I could rattle off a dozen NNSA projects over the last 15 years in which costs have exploded, wasting tens of billions of taxpayers’ dollars.

But get this, future pit production is also unnecessary and may actually degrade national security. To begin with, independent experts have found that pits have serviceable lifetimes of at least a century (their average age is now around 40). And we already have at least 15,000 existing pits stored at the Pantex Plant near Amarillo, TX.

A Guide to “Scoping” the New LANL SWEIS

Sophia MerynPit Production at LANL, Plutonium Pit Production, Sandia National Laboratories

“Scoping” means determining the issues that should be included in public analyses required by the National Environmental Policy Act (NEPA) of proposed major actions by the federal government. According to the Department of Energy ‘s own NEPA implementation regulations, DOE must prepare a new or supplemental site-wide environmental impact statement (SWEIS) for its major sites when there are “significant new circumstances or information relevant to environmental concerns.” The last site-wide EIS for the Los Alamos National Laboratory (LANL) was completed in 2008 and is badly outdated. Moreover, since 2018 the National Nuclear Security Administration (NNSA), DOE’s semi-autonomous nuclear weapons agency, has been aggressively expanding the production of plutonium “pit” bomb cores for nuclear weapons at the Lab.

On August 19, 2022, NNSA finally announced its intent to prepare a new LANL SWEIS, but apparently the agency will not address expanded plutonium pit production.1 NNSA’s dubious argument is that it performed the legally required NEPA analysis for expanded plutonium pit production in a 2008 Complex Transformation Programmatic Environmental Impact Statement, the 2008 LANL SWEIS and a woefully inadequate “Supplement Analysis” in 2020 that concluded a new SWEIS was not needed. 2 3

Issues That Must Be Addressed in a New LANL SWEIS

This is meant to be a guide to (or list of) the issues that must be addressed in a new draft LANL SWEIS. It is not completely exhaustive, nor is it a comprehensive fact sheet on the substance of the issues.

Signs Calling for a Future of Peace Through a Reminder of the Past

Sophia MerynJapan, Los Alamos Nat'l Lab., New Mexico, Nuclear Policy, Nuclear Weapons, Pit Production at LANL, Plutonium Pit Production, Sandia National Laboratories

Less than a week before the Christmas holiday, over 125 people came together at the statue of Our Lady of Guadalupe in the afternoon of Sunday, December 19th to listen to Archbishop John C. Wester of the Archdiocese of Santa Fe give a blessing to two “signs of peace” he unveiled on-site during a short ceremony. The signs were revealed to show an image of Pope Francis and a quote uttered by the pope in Hiroshima in 2020: “The possession of nuclear arms is immoral.” During the blessing, the Archbishop spoke on his memories of “those days during the Cuban missile crisis when I would walk home from school having been instructed what to do in the event of a nuclear attack within a few thousand yards of a nuke missile site in San Francisco,” before issuing a call for the world to rid itself its nuclear weapons.

“We need to be instruments of peace,” he said, especially as we head into the Christmas season, a “season of peace.”

Wester said that the current arms race “is more ominous” than any that came before. He touched on the growing tension around the Russia-Ukraine border in mentioning that there are at least “40 active conflicts in the world,” and said “our archdiocese needs to be facilitating, encouraging an ongoing conversation” about nuclear disarmament. This is especially true in light of the fact that two of the US’s three nuclear weapons laboratories are to be found in the dioceses of Sandia and Los Alamos, and on top of that there are more nuclear warheads in his dioceses from the 2,500-some count stored in reserve at the Kirtland Air Force Base at Albuquerque. All of this means that more money is spent in his dioceses than any other dioceses in the country and perhaps the world.

Sophia MerynLos Alamos Nat'l Lab., New Mexico, Pantex Plant, Pit Production, Pit Production at LANL, Pit Production at SRS, Plutonium Pit Production, Savannah River Site, WIPP

The original mission of the Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico had two specific stipulations: it was to be the FIRST and only operating underground nuclear waste repository in U.S; and it is ONLY authorized to take a certain kind of nuclear weapons waste – legacy transuranic (TRU) waste. In December of last year, the U.S. Department of Energy published a notice of intent to expand WIPP. The notice details expansion of the plant in two ways: capacities and types of waste permissible, as well as extended storage/operation timelines. The federal government’s plans would expand the size of the nuclear weapons dump to more than twice its current size and more than is allowed: Federal law and legal agreements with New Mexico clearly limit the amount of waste at WIPP, but the expansion would allow more than that capacity (as described in the April 2020 National Academy of Sciences Report “Review of the Department of Energy’s Plans for Disposal of Surplus Plutonium in the Waste Isolation Pilot Plant.”) This means an increased volume of waste, as well as an increased number of shipments travelling to WIPP over the entire rest of the century.

The original complete set of legal permits, contracts and laws governing WIPP includes the Federal Resource Conservation and Recovery Act (RCRA), which 1) gives the New Mexico Environment Department regulation over the permit for DOE operation of WIPP and 2) limits amount of waste and how long WIPP operates (2024);

South Carolina Environmental Law Project and Nuclear Watchdogs Virtual Press Conference

Sophia MerynLos Alamos Nat'l Lab., Pit Production at LANL, Pit Production at SRS, Plutonium Pit Production, Savannah River Site

Nuclear Watch New Mexico, along with other watchdog groups, has announced a lawsuit against the Biden administration over its expanded production of plutonium cores for the U.S. nuclear weapons “modernization” plans. There has been inadequate environmental review by federal agencies, who have failed to detail potential impacts of the projects around communities in New Mexico and South Carolina.

The lawsuit was filed against the Energy Department and the National Nuclear Security Administration demanding the federal agency that oversees U.S. nuclear research and bombmaking must “take a legally required ‘hard look’ at impacts on local communities and possible alternatives before expanding manufacturing of the plutonium cores used to trigger nuclear weapons.”

The push from U.S. officials to “modernize” the country’s nuclear arsenal cites only general global security concerns that do not justify the science and brand new, untested technology that will be necessary to the task. citing global security concerns. Although “most of the plutonium cores currently in the stockpile date back to the 1970s and 1980s,” scientific experts estimate that plutonium pits will last 100 years or more., and on warhead type, the best estimate of minimum pit life is 85–100 years.minimum.

Los Alamos National Laboratory in northern New Mexico and the Savannah River Site near Aiken, South Carolina face enormous (and, frankly, unrealistic) deadlines to produce a massive number of plutonium cores in coming years – 50 or more cores at South Carolina and 30 or more at Los Alamos National Lab. The Savannah River Site location now has estimated costs up to $11.1 billion, with a completion date ranging from 2032 to 2035. The U.S. doesn’t need the new plutonium cores with the taxpayer bearing the burden for the expense of lagging deadlines and bloated budgets.

“The watchdog groups said Tuesday that the agency took a piecemeal approach to decide on locating the production at Los Alamos and the Savannah River Site, where nearby communities are already underrepresented and underserved.”

Tom Clements of Savannah River Site Watch said the South Carolina location was picked for political reasons following the failure of a facility designed to convert weapons-grade plutonium into commercial nuclear fuel. As the Savannah River Site has never served as a storage or production site for the pits in its history, establishing pit construction there would be “a daunting technical challenge that has not been properly reviewed,” Clements said.

With very real, current threats the U.S. is facing right now, we don’t need another Rocky Flats situation in New Mexico or South Carolina where a $7 billion, yearslong cleanup is required after the facilities fail due to leaks, fires and environmental violations, doing irreparable damage to the earth and placing communities there in unequivocal peril.

Nuclear Watch New Mexico virtually visited Washington, DC this month to participate in the Alliance for Nuclear Accountability’s “DC Days,” an annual event where organizations from across the nation, whose members are directly affected by nuclear weapons production and the incidental health and environmental consequences, make their voice heard to federal policy makers.

Nuclear Watch NM was focused on opposing new plutonium pit production at Savannah River Site and Los Alamos, pushing for safe and secure toxic cleanup and prioritizing public health while saving billions by terminating ill-conceived new nuclear weapons programs. View more information on these issues in the Alliance for Nuclear Accountability’s new report, “Safety, Security, and Savings,” which describes in detail the foundation of our 2021 advocacy. The report includes a series of fact sheets and recommendations covering new warheads, bomb plants, nuclear waste, cleanup, and more.

Notice of Impending Lawsuit to DOE & NNSA Over Nuclear Bomb Core Plans from Environmental Groups

Nuclear Watch New Mexico, as part of a larger coalition of environmental groups, has threatened the federal government with a lawsuit over cross-country plans to produce plutonium pits, the cores at the heart of modern nuclear weapons.

A more comprehensive review should have been done on the plans to produce plutonium cores at Los Alamos and at the Savannah River Site in South Carolina. This lack of review violates the National Environmental Policy Act (NEPA) and would saddle already-burdened communities nearby the two DOE sites with significant quantities of toxic and radioactive waste, contravening President Biden’s executive order of making environmental justice a part of the mission of every agency. Here in New Mexico, we are well aware of how much our local community has already have been burdened with legacy contamination from previous defense work. While the budget continues to be cut and slashed for cleanup funding, the astronomical cost of modernizing the U.S. nuclear weapons arsenal continues to balloon out of proportion without NNSA or DOE batting an eyelash. The federal government’s plans are unnecessary and provocative – more plutonium pit production will result in more waste and help to fuel a new arms race.

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.

Santa Fe, NM – Today the Department of Energy’s semi-autonomous nuclear weapons agency, the National Nuclear Security Administration (NNSA), announced that it will not complete a new site-wide environmental impact statement for the Los Alamos National Laboratory (LANL). The last site-wide environmental impact statement was in 2008.

Since that time a catastrophic wildfire burned to the western boundary of the Lab (likely to occur more frequently with climate change); an exploding radioactive waste drum improperly prepared by LANL shut down the Waste Isolation Pilot Plant for three years, costing taxpayers ~$3 billion to reopen; the full extent and depth of a hexavalent chromium plume contaminating the regional groundwater is still not fully determined; and LANL’s long track record of chronic nuclear safety incidences remain unresolved.

The Department of Energy’s semi-autonomous National Nuclear Security Administration (NNSA) has formally announced that it is proceeding with aggressive plans to expand the production of plutonium pits without required nation-wide “programmatic” public review. The Natural Resources Defense Council, Nuclear Watch New Mexico, Savannah River Site Watch and Tri-Valley CAREs assert this is in direct violation of the legal requirements of both the National Environmental Policy Act and a 1998 court order that stipulates that DOE must prepare a “programmatic environmental impact statement” (PEIS) when it plans to produce more than 80 pits per year. Plutonium pits are the radioactive cores or “triggers” of nuclear weapons.
