‘Her legs turned blue’: Nuclear plant radiation led to 12-inch blood clot in teen’s hip and deadly complications after she played in nearby creek, lawsuit says

An Ohio teenager died from complications of a bone marrow transplant after developing a “rare” genetic condition caused by radiation from a nuclear plant she lived by, her mother says in a lawsuit. The teen was diagnosed with a 12-inch blood clot in her hip and blood clots in her lungs before she died.

“Cheyenne Dunham, from birth until she was a teenager, regularly consumed food grown in a garden within close proximity to [the nuclear plant], including corn, tomatoes and beans,” lawyers for Cheyenne’s mother say in a 52-page legal complaint. “Cheyenne Dunham lived from age 4 or 5 until she was a teenager … in close proximity to [the nuclear plant]. At this home, Cheyenne Dunham played in a creek and ingested creek water.”

Cheyenne’s mother, Julia Dunham, is suing Centrus Energy in a wrongful death case for her 19-year-old daughter’s death in 2015. Julia became the administrator of Cheyenne’s estate in October and filed her complaint against Centrus Energy in late November. She says radiation from the company’s Portsmouth Gaseous Diffusion Plant, referred to as PORTS, led to Cheyenne’s condition and health problems.

Officials shut down the plant in 2001 due to environmental concerns, including the proximity of a school just two miles away and numerous nearby homes.

On May 13, 2019, Zahn’s Corner Middle School in Piketon was “suddenly closed” after “enriched uranium” was detected inside the building, according to Julia Dunham’s complaint. Cheyenne was a student there for three years, from fourth through sixth grade.

“While at Zahn’s Corner, Cheyenne was exposed to radionuclides in excess of federal regulatory limits,” the complaint alleges. “She was also exposed to radionuclides in the Piketon community.”

The AI Arms Race Is Cracking Open The Nuclear Fuel Cycle

  • The abstract “cloud” of artificial intelligence possesses a massive, structural demand for 24/7 “baseload” power that is equivalent to adding Germany’s entire power grid by 2026, a need intermittent renewables cannot meet.
  • Decades of underinvestment have resulted in a widening uranium supply deficit, with mined uranium expected to meet less than 75% of future reactor needs and an incentive price of $135/lb required to restart mothballed mines.
  • Big Tech hyperscalers are privatizing energy security by locking in clean baseload nuclear power via long-term agreements, effectively making the public grid’s “service” secondary to the “compute-ready” requirements of major platforms.

We are seeing a violent collision between two worlds: the high-speed, iterative world of artificial intelligence and the slow, grinding, capital-intensive world of nuclear physics. 

Data from a survey of over 600 global investors reveals that 63% now view AI electricity demand as a “structural” shift in nuclear planning. This isn’t a temporary spike or a speculative bubble. It is the physical footprint of every Large Language Model (LLM) query finally showing up on the global balance sheet.

For years, the energy narrative was dominated by “efficiency.” We were told that better chips would offset higher usage. That era is over. Generative AI doesn’t just use data; it incinerates energy to create it.

Why the “Efficiency” Narrative Failed

The “Reverse-Polish” reality of AI is that the more efficient we make the chips, the more chips we deploy, and the more complex the models become. This is Jevons Paradox playing out in real-time across the data centers of Northern Virginia and Singapore.

When you look at the energy density required for an AI hyperscale center, you aren’t looking at a traditional office building. You are looking at a facility that pulls as much power as a mid-sized city, but does so with a 99.999% uptime requirement.

Traditional demand models simply didn’t account for a single industry deciding to double its power footprint in less than five years. S&P Global Energy recently highlighted that data center electricity consumption could hit 2,200 terawatt-hours (TWh). 

Intermittent renewables…the darlings of the corporate ESG report…cannot provide the 24/7 “baseload” these machines require…

The hyperscalers have realized that if they want to dominate AI, they need to secure physical atoms before the other guy does.

Russia to build nuclear plant on Moon to power rovers, labs during 336-hour long nights

Russia has unveiled its plans to build a nuclear power plant on the Moon within the next 10 years to support its lunar program and a Russian-Chinese research station for future deep-space missions.

The proposal, confirmed by the country’s state space agency Roscosmos, would provide a sustained energy source for surface infrastructure, including rovers, scientific equipment, as well as a planned joint lunar research base with China.

The announcement followed as the US, India, Japan as well as several European nations increased efforts to establish a permanent presence on Earth’s only natural satellite. The renewed interest was prompted by the 2009 discovery of water ice on the lunar surface.

Power generation remains a great challenge for sustained lunar operations due to the two-week-long nights that restrict solar power. However, a nuclear power plant could offer continuous power regardless of lighting conditions, temperature extremes, or dust accumulation.

Nuclear energy for space

For the 2036 project, Roscosmos revealed that it has signed a contract with the Lavochkin Association, a Russian aerospace firm with decades of experience in planetary spacecraft development.

Even though the space agency did not explicitly describe the facility as a nuclear reactor, it confirmed the initiative involves Rosatom, the nation’s state nuclear corporation, as well as the Kurchatov Institute, Russia’s leading nuclear research center.

According to Roscosmos, the lunar power plant would support a broad range of activities tied to Russia’s lunar program. These include powering robotic rovers, an observatory and maintaining the infrastructure of the planned International Lunar Research Station.

“The project is an important step towards the creation of a permanently functioning scientific lunar station and the transition from one-time missions to a long-term lunar exploration programme,” Roscosmos said.

China Successfully Operates World’s First Thorium Molten Salt Reactor

An experimental Chinese nuclear plant reportedly just crossed a historic threshold, successfully operating the world’s first thorium-based molten salt reactor (TMSR). The Chinese Academy of Sciences’ Shanghai Institute of Applied Physics has broken a major scientific barrier by successfully converting thorium to uranium in a historic first.

The Hong Kong-based South China Morning Post reports that the breakthrough, which took place at an experimental reactor out in the Gobi Desert, is “poised to reshape the future of clean sustainable nuclear energy.” 

The process works by using a “precise sequence of nuclear reactions” in which naturally occurring thorium-232 absorbs a neutron, becoming thorium-233. Through a decay process, that isotope breaks down into protactinium-233 and then finally into uranium-233, a potent form of nuclear fuel that can sustain chain reactions for nuclear fission.

While this breakthrough was just publicized this month by a report by Science and Technology Daily, the TMSR has apparently been operational for years. Li Qingnuan, Communist Party secretary and deputy director at the Shanghai Institute of Applied Physics, told the outlet that “since achieving first criticality on October 11, 2023, the thorium molten salt reactor has been steadily generating heat through nuclear fission”.

If the reports are true, this breakthrough would signal an incredible leap forward in a nuclear technology race that China is already winning handily. Although the United States is still the world’s biggest producer of nuclear energy, that status won’t last much longer. In the same time period that the United States built the overdue and over-budget Plant Vogtle, China built 13 reactors of similar scale, and has 33 more on the way. Beijing is also making major forays into the nuclear sectors of emerging economies, with particularly concerted efforts in Africa.

“The Chinese are moving very, very fast,” Mark Hibbs, senior fellow at the Carnegie Endowment for International Peace and expert on the Chinese nuclear sector, told the New York Times. “They are very keen to show the world that their program is unstoppable.”

The Trump Administration’s Top Nuclear Scientists Think AI Can Replace Humans in Power Plants

During a presentation at the International Atomic Energy Agency’s (IAEA) International Symposium on Artificial Intelligence on December 3, a US Department of Energy scientist laid out a grand vision of the future where nuclear energy powers artificial intelligence and artificial intelligence shapes nuclear energy in “a virtuous cycle of peaceful nuclear deployment.”

“The goal is simple: to double the productivity and impact of American science and engineering within a decade,” Rian Bahran, DOE Deputy Assistant Secretary for Nuclear Reactors, said.

His presentation and others during the symposium, held in Vienna, Austria, described a world where nuclear powered AI designs, builds, and even runs the nuclear power plants they’ll need to sustain them. But experts find these claims, made by one of the top nuclear scientists working for the Trump administration, to be concerning and potentially dangerous. 

Tech companies are using artificial intelligence to speed up the construction of new nuclear power plants in the United States. But few know the lengths to which the Trump administration is paving the way and the part it’s playing in deregulating a highly regulated industry to ensure that AI data centers have the energy they need to shape the future of America and the world.

At the IAEA, scientists, nuclear energy experts, and lobbyists discussed what that future might look like. To say the nuclear people are bullish on AI is an understatement. “I call this not just a partnership but a structural alliance. Atoms for algorithms. Artificial intelligence is not just powered by nuclear energy. It’s also improving it because this is a two way street,” IAEA Director General Rafael Mariano Grossi said in his opening remarks.

In his talk, Bahran explained that the DOE has partnered with private industry to invest $1 trillion to “build what will be an integrated platform that connects the world’s best supercomputers, AI systems, quantum systems, advanced scientific instruments, the singular scientific data sets at the National Laboratories—including the expertise of 40,000 scientists and engineers—in one platform.”

Energy Department loans $1B to help finance the restart of nuclear reactor on Three Mile Island

The U.S. Department of Energy said Tuesday that it will loan $1 billion to help finance the restart of the nuclear power plant on Pennsylvania’s Three Mile Island that is under contract to supply power to data centers for tech giant Microsoft.

The loan is in line with the priorities of President Donald Trump’s administration, including bolstering nuclear power and artificial intelligence.

For Constellation Energy, which owns Three Mile Island’s lone functioning nuclear power reactor, the federal loan will lower its financing cost to get the mothballed plant up and running again. The 835-megawatt reactor can power the equivalent of approximately 800,000 homes, the Department of Energy said.

The reactor had been out of operation for five years when Constellation Energy announced last year that it would spend $1.6 billion to restart it under a 20-year agreement with Microsoft to buy the power for its data centers.

Constellation Energy renamed the functioning unit the Crane Clean Energy Center as it works to restore equipment including the turbine, generator, main power transformer and cooling and control systems. It hopes to bring the plant back online in 2027.

The loan is being issued under an existing $250 billion energy infrastructure program initially authorized by Congress in 2022. Neither the department nor Constellation released terms of the loan.

The plant, on an island in the Susquehanna River just outside Harrisburg, was the site of the nation’s worst commercial nuclear power accident, in 1979. The accident destroyed one reactor, Unit 2, and left the plant with one functioning reactor, Unit 1.

In 2019, Constellation Energy’s then-parent company Exelon shut down the functioning reactor, saying it was losing money and Pennsylvania lawmakers had refused to subsidize it to keep it running.

The plan to restart the reactor comes amid something of a renaissance for nuclear power, as policymakers are increasingly looking to it to shore up the nation’s power supply, help avoid the worst effects of climate change and meet rising power demand driven by data centers.

Trump Admin To Lend “Hundreds Of Billions” To Build Nuclear Power Plants

While the market is finally starting to grapple with the most unpleasant question of who will plug the funding gap needed to build out all the data centers required to make the AI dream a reality, a gap which Morgan Stanley recently calculated would be as large as $2.9 trillion in capex funding needs, of which at least $1 trillion will come in the form of debt (and mostly private debt)…

… there is another, just as critical question: who will fund the energy buildout that powers these data centers? 

Recall, last December Morgan Stanley calculated that the US would need at least 36GW in new power to be brought online by 2028 to energize all the (yet to be built) data centers, a number which one year later is surely far higher.

The largest project in the history of humanity is about to enter a key phase the final assembly of the reactor core led by an american giant

The world’s largest and most ambitious fusion energy project has reached a turning point as Westinghouse Electric Company begins assembling the heart of ITER’s fusion reactor in Cadarache, southern France. The international effort, designed to replicate the energy of the sun, could one day provide humanity with an endless supply of clean, sustainable power.

Westinghouse leads final assembly of ITER’s tokamak core

In August 2025, the ITER fusion project entered one of its most technically demanding phases — the final assembly of the reactor’s tokamak core. Westinghouse, a global leader in nuclear technology, secured a €168 million contract to oversee the installation and welding of nine giant steel sectors that will form the tokamak’s vacuum vessel, the central chamber where fusion will occur.

This donut-shaped vessel must be perfectly circular and hermetically sealed, as it will contain plasma heated to over 150 million degrees Celsius—hotter than the core of the sun. Each sector, weighing about 400 tons, requires millimeter-level precision to ensure the system’s stability and safety during operation.

Westinghouse’s experience spans over a decade of work with Ansaldo Nucleare and Walter Tosto through the AMW consortium, which produced five of the nine reactor sectors. Their expertise ensures precision in both construction and integration, as the vessel must endure enormous magnetic and thermal stresses.

As former ITER Director-General Bernard Bigot once said, “Assembling this is like putting together a three-dimensional puzzle on an industrial scale.” Every weld, joint, and component must perform flawlessly to contain a process capable of replicating stellar reactions on Earth.

Global collaboration of unprecedented scale

ITER (International Thermonuclear Experimental Reactor) represents one of the greatest examples of scientific collaboration in history. Bringing together 35 nations—including the European Union, the United States, China, Japan, Russia, India, and South Korea—the project unites over half the world’s population and 85% of global GDP toward a common goal: sustainable energy.

Each participating country contributes precision-built components manufactured across four continents, shipped to France for assembly. This global supply chain transforms ITER into a model for future international cooperation in large-scale science and technology projects.

The result is more than just a reactor—it’s a demonstration of how humanity can coordinate resources and knowledge to solve planetary challenges, setting a precedent for future global energy innovations.

Technical ambitions and timeline challenges

ITER’s goal is to produce 500 megawatts of fusion power from just 50 megawatts of input—a tenfold return that would confirm the commercial viability of nuclear fusion. Achieving this would redefine global energy systems and represent a technological breakthrough comparable to the invention of electricity itself.

However, progress hasn’t come without challenges. Since construction began in 2010, ITER’s timeline has been extended multiple times due to technical complexity, supply chain coordination, and the unprecedented scale of the project. Originally scheduled for first plasma by 2018, the target now stands at 2035 for the first deuterium-tritium fusion experiments.

This delay underscores fusion’s enduring difficulty: creating and maintaining the extreme conditions necessary for sustained reaction. As the saying goes in the industry, “Fusion is always 30 years away”—a reminder of both the ambition and patience required for such pioneering work.

DOE And NRC Sign Addendum To Fast Track Commercial Reactor Licensing

The Department of Energy (DOE) and the Nuclear Regulatory Commission (NRC) recently signed Addendum No. 9 to their 2019 Memorandum of Understanding (MOU), paving the way for faster follow-on licensing of advanced nuclear reactors and nuclear fuel technologies.

This agreement, signed Oct 24th and effective immediately, comes as major concerns have been raised by reactor development companies and industry observers regarding the double work that may be required of developers when they bring their tested products over to the NRC. Demand for clean, reliable energy by data centers and major industrial companies has created a stronger need for change in the path to reactor design commercialization, with companies like Microsoft, Google, and Amazon signing long-term offtake agreements with reactor operators Constellation, NextEra, and Talen.

The addition to the MOU comes from the directives out of Trump’s executive orders signed back in May of this year. From section 5.d of the executive order “Ordering the Reform of the Nuclear Regulatory Commission”:

“Establish an expedited pathway to approve reactor designs that the DOD or the DOE have tested and that have demonstrated the ability to function safely. NRC review of such designs shall focus solely on risks that may arise from new applications permitted by NRC licensure, rather than revisiting risks that have already been addressed in the DOE or DOD processes.”

Surprisingly, the DOE and NRC took the executive order one step further and included a streamlined licensing process for nuclear fuel facilities as well. It becomes less surprising when we remember the current administration has highlighted multiple times the desire to reduce the reliance on foreign nuclear fuel supplies. Even with the Russian uranium import ban, the US is still importing over a fifth of the required enriched uranium from Russia through last year. The US government is looking to expand the domestic capacity of every step in the fuel chain as quickly as possible.

The new addendum will directly impact the companies already announced by the DOE as participants in their pilot reactor and fuel programs:

  • Reactor developers: Aalo Atomics, Antares Nuclear, Atomic Alchemy, Deep Fission, Last Energy, Oklo (two projects), Natura Resources, Radiant Industries, Terrestrial Energy, Valar Atomics
  • Fuel facilities: Standard Nuclear, Oklo, Terrestrial Energy, TRISO-X, Valar Atomics

Additional companies are expected to be announced for both of the programs in the near future, as the DOE still looks to expand the number of participants as an effort to increase the chance of success.

Republican Socialism Goes Nuclear: Trump Bets $80 Billion on Government-Backed Energy

Since President Donald Trump’s return to the Oval Office, the federal government has trademarked its own version of Republican socialism by nationalizing steel production and taking equity stakes in chip manufacturers and mining projects. Now, it’s getting involved in the nuclear power sector. 

On Tuesday, Westinghouse Electric Company announced that it had entered “into a strategic partnership” with the federal government, Brookfield Asset Management, and uranium fuel supplier Cameco Corporation to build “at least” $80 billion worth of Westinghouse’s AP1000 nuclear reactors across the country. The agreement was made “in accordance” with Trump’s May executive order, which called for the deployment of 10 new large nuclear reactors in the U.S. by 2030, according to Westinghouse. 

The details of the agreement are still a bit murky, but the federal government will underwrite at least some of these projects, while others might be financed by Japan. On Tuesday, Japan’s trade ministry pledged to invest $550 billion into American projects, in exchange for lower tariff rates from the Trump administration. Included in this package was an “artificial intelligence and a nuclear reactor construction initiative that was expected to be worth up to $100 billion and involve Mitsubishi Heavy [Industries] and Toshiba,” reports The New York Times. 

The deal might also allow the federal government to take an equity stake in America’s largest nuclear power company. Bloomberg‘s Liam Denning writes that as long as the U.S. government follows through on its financial commitment, “it would then get a 20% share in any dividends paid out by Westinghouse above a $17.5 billion threshold.” If these projects are up and running within the next “three years or so” and “Westinghouse is deemed at that point to be worth at least $30 billion, the company may then be required to do an initial public offering with the government getting warrants that may convert into an equity stake,” according to Denning. 

Nuclear power is clean, reliable, and safe, but forcing taxpayers to bet on its future success is risky. After thriving throughout the ’60s, ’70s, and ’80s, the industry has been plagued by P.R. disasters and project failures that have hampered nuclear power for much of the last 30 years. 

Recent efforts to revive the industry have not done much to build public confidence. A failed nuclear power plant project in South Carolina, which featured two AP1000 reactors, left ratepayers on the hook for millions of dollars, although Brookfield Management is considering reviving the project, according to the Associated Press.
