A Small Town Is Fighting a $1.2 Billion AI Datacenter for America's Nuclear Weapon Scientists

Hey there,

Across the country, communities are learning about the reality of having an AI datacenter erected in their town. We've heard stories about energy prices, impacts on drinking water, and the environmental cost of rapidly built AI infrastructure. Today, Matthew Gault has a story about a small town's unique fight against an AI datacenter that's being built by the same laboratory that developed America's nuclear weapons.

Ypsilanti, Michigan resident KJ Pedri doesn’t want her town to be the site of a new $1.2 billion data center, a massive collaborative project between the University of Michigan and America’s nuclear weapons scientists at Los Alamos National Laboratories (LANL) in New Mexico.

“My grandfather was a rocket scientist who worked on Trinity,” Pedri said at a recent Ypsilanti city council meeting, referring to the first successful detonation of a nuclear bomb. “He died a violent, lonely, alcoholic. So when I think about the jobs the data center will bring to our area, I think about the impact of introducing nuclear technology to the world and deploying it on civilians. And the impact that that had on my family, the impact on the health and well-being of my family from living next to a nuclear test site and the spiritual impact that it had on my family for generations. This project is furthering inhumanity, this project is furthering destruction, and we don’t need more nuclear weapons built by our citizens.”

At the Ypsilanti city council meeting where Pedri spoke, the town voted to officially fight against the construction of the data center. The University of Michigan says the project is not a data center, but a “high-performance computing facility” and it promises it won’t be used to “manufacture nuclear weapons.” The distinction and assertion are ringing hollow for Ypsilanti residents who oppose construction of the data center, have questions about what it would mean for the environment and the power grid, and want to know why a nuclear weapons lab 24 hours away by car wants to build an AI facility in their small town.

Attack surfaces are expanding fast—driven by shadow IT, supply chains and rapid cloud adoption. Intruder’s 2025 Exposure Management Index—built from data across 3,000+ organizations—reveals how security teams are adapting to this new reality. Key findings: AI is helping attackers weaponize the back catalog of CVEs, turning old vulnerabilities into new opportunities for exploitation. In a reversal from 2024, European organizations are pulling ahead of North America in critical vulnerability management, facing fewer critical issues. Thousands of CVEs are published each year, but only a handful truly matter. We’ve identified the five vulnerabilities that defined 2025 and what they teach defenders about real-world risk.

“What I think galls me the most is that this major institution in our community, which has done numerous wonderful things, is making decisions with—as I can tell—no consideration for its host community and no consideration for its neighboring jurisdictions,” Ypsilanti councilman Patrick McLean said during a recent council meeting. “I think the process of siting this facility stinks.”

For others on the council, the fight is more personal.

“I’m a Japanese American with strong ties to my family in Japan and the existential threat of nuclear weapons is not lost on me, as my family has been directly impacted,” Amber Fellows, a Ypsilanti Township councilmember who led the charge in opposition to the data center, told 404 Media. “The thing that is most troubling about this is that the nuclear weapons that we, as Americans, witnessed 80 years ago are still being proliferated and modernized without question.”

It’s a classic David and Goliath story. On one side is Ypsilanti (called Ypsi by its residents), which has a population just north of 20,000 and situated about 40 minutes outside of Detroit. On the other is the University of Michigan and Los Alamos National Laboratories (LANL), American scientists famous for nuclear weapons and, lately, pushing the boundaries of AI.

The University of Michigan first announced the Los Alamos data center, what it called an “AI research facility,” last year. According to a press release from the university, the data center will cost $1.25 billion and take up between 220,000 to 240,000 square feet. “The university is currently assessing the viability of locating the facility in Ypsilanti Township,” the press release said.

On October 21, the Ypsilanti Township City Council considered a proposal to officially oppose the data center and the people of the area explained why they wanted it passed. One woman cited environmental and ethical concerns. “Third is the moral problem of having our city resources towards aiding the development of nuclear arms,” she said. “The city of Ypsilanti has a good track record of being on the right side of history and, more often than not, does the right thing. If this resolution passed, it would be a continuation of that tradition.”

A man worried about what the facility would do to the physical health of citizens and talked about what happened in other communities where data centers were built. “People have poisoned air and poisoned water and are getting headaches from the generators,” he said. “There’s also reports around the country of energy bills skyrocketing when data centers come in. There’s also reports around the country of local grinds becoming much less reliable when the data centers come in…we don’t need to see what it’s like to have a data center in Ypsi. We could just not do that.”

The resolution passed. “The Ypsilanti City Council strongly opposes the Los Alamos-University of Michigan data center due to its connections to nuclear weapons modernization and potential environmental harms and calls for a complete and permanent cessation of all efforts to build this data center in any form,” the resolution said.

Ypsi has a lot of reasons to be concerned. Data centers tend to bring rising power bills, horrible noise, and dwindling drinking water to every community they touch. “The fact that U of M is using Ypsilanti as a dumping ground, a sacrifice zone, is unacceptable,” Fellows said.

Ypsi’s resolution focused on a different angle though: nuclear weapons. “The Ypsilanti City Council strongly opposes the Los Alamos-University of Michigan data center due to its connections to nuclear weapons modernization and potential environmental harms and calls for a complete and permanent cessation of all efforts to build this data center in any form,” the resolution said.

As part of the resolution, Ypsilanti Township is applying to join the Mayors for Peace initiative, an international organization of cities opposed to nuclear weapons and founded by the former mayor of Hiroshima. Fellows learned about Mayors for Peace when she visited Hiroshima last year.

Both LANL and the University of Michigan have been vague about what the data center will be used for, but have said it will include one facility for classified federal research and another for non-classified research which students and faculty will have access to. “Applications include the discovery and design of new materials, calculations on climate preparedness and sustainability,” it said in an FAQ about the data center. “Industries such as mobility, national security, aerospace, life sciences and finance can benefit from advanced modeling and simulation capabilities.”

The university FAQ said that the data center will not be used to manufacture nuclear weapons. “Manufacturing” nuclear weapons specifically refers to their creation, something that’s hard to do and only occurs at a handful of specialized facilities across America. I asked both LANL and the University of Michigan if the data generated by the facility would be used in nuclear weapons science in any way. Neither answered the question.

“The federal facility is for research and high-performance computing,” the FAQ said. “It will focus on scientific computation to address various national challenges, including cybersecurity, nuclear and other emerging threats, biohazards, and clean energy solutions.”

LANL is going all in on AI. It partnered with OpenAI to use the company’s frontier models in research and recently announced a partnership with NVIDIA to build two new super computers named “Mission” and “Vision.” It’s true that LANL’s scientific output covers a range of issues but its overwhelming focus, and budget allocation, is nuclear weapons. LANL requested a budget of $5.79 billion in 2026. 84 percent of that is earmarked for nuclear weapons. Only $40 million of the LANL budget is set aside for “science,” according to government documents. 

“The fact is we don’t really know because Los Alamos and U of M are unwilling to spell out exactly what’s going to happen,” Fellows said. When LANL declined to comment for this story, it told 404 Media to direct its question to the University of Michigan.

The university pointed 404 Media to the FAQ page about the project. “You'll see in the FAQs that the locations being considered are not within the city of Ypsilanti,” it said.

It’s an odd statement given that this is what’s in the FAQ: “The university is currently assessing the viability of locating the facility in Ypsilanti Township on the north side of Textile Road, directly across the street from the Ford Rawsonville Components plant and adjacent to the LG Energy Solutions plant.”

It’s true that this is not technically in the city of Ypsilanti but rather Ypsilanti Township, a collection of communities that almost entirely surrounds the city itself. For Fellows, it’s a distinction without a difference. “[Univeristy of Michigan] can build it in Barton Hills and see how the city of Anne Arbor feels about it,” she said, referencing a village that borders the township where the university's home city of Anne Arbor.

“The university has, and will continue to, explore other sites if they are viable in the timeframe needed for successful completion of the project,” Kay Jarvis, the university’s director of public affairs, told 404 Media.

Fellows said that Ypsilanti will fight the data center with everything it has. “We’re putting pressure on the Ypsi township board to use whatever tools they have to deny permits…and to stand up for their community,” she said. “We’re also putting pressure on the U of M board of trustees, the county, our state legislature that approved these projects and funded them with public funds. We’re identifying all the different entities that have made this project possible so far and putting pressure on them to reverse action.”

For Fellows, the fight is existential. It’s not just about the environmental concerns around the construction project. “I was under the belief that the prevailing consensus was that nuclear weapons are wrong and they should be drawn down as fast as possible. I’m trying to use what little power I have to work towards that goal,” she said.
