The West Texas metropolis of Abilene is best identified for nation music and rodeos than superior nuclear physics. However that’s the place scientists are coming into the ultimate stretch of a race besides up the following technology of American atomic vitality.
Amid a flurry of nuclear startups across the nation, Abilene-based Natura Sources is certainly one of simply two firms with permits from the U.S. Nuclear Regulatory Fee to assemble a so-called “advanced” reactor. It should construct its small, one megawatt molten salt reactor beneath a newly-completed laboratory at Abilene Christian College, in an underground trench 25 ft deep and 80 ft lengthy, lined by a concrete lid and serviced by a 40-ton building crane.
The opposite firm, California-based Kairos Energy, is constructing its 35 megawatt take a look at reactor in Oak Ridge, Tennessee, the 80-year capital of American nuclear energy science. Each goal completion in 2027 and hope to usher in a brand new chapter of the vitality age.
“A company and school no one has heard of has gotten to the forefront of advanced nuclear,” mentioned Rusty Towell, a nuclear physicist at Abilene Christian College and lead developer of Natura’s reactor. “This is going to bless the world.”
The U.S. Division of Power has been working for years to resuscitate the American nuclear sector, advancing the event of recent reactors to satisfy the big incoming electrical calls for of massive new industrial services, from knowledge facilities and Bitcoin mines to chemical crops and desalination services.
Leaders in Texas, the nation’s largest vitality producer and shopper, have declared intentions to courtroom the rising nuclear sector and settle it in state. The challenge at Abilene Christian College is only one of a number of early superior reactor deployments already deliberate right here.
Dow Chemical plans to position small reactors made by X-energy at its Seadrift advanced on the Gulf Coast. Final month, Natura introduced plans to energy oilfield infrastructure within the Permian Basin. And in February, Texas A&M College introduced that 4 firms, together with Natura and Kairos, would construct small, 250 megawatt commercial-scale reactors at a large new “proving grounds” close to its campus in School Station.
“We need energy in Texas, we need a lot of it and we need it fast,” mentioned state Sen. Charles Perry, chair of the Senate Committee on Water, Agriculture and Rural Affairs. “The companies that are coming here are going to need a different type of energy long term.”
Throughout this 12 months’s biennial legislative session, state lawmakers are hoping to make billions of {dollars} of public financing accessible for brand spanking new nuclear initiatives, and to cross different payments in help of the sector.
“If we do what we’re asked to do from industry groups out here, if we do what we think we should do and we know we should do, we could actually put a stake in the ground that Texas is the proving ground for these energies,” Perry mentioned, talking this month within the state Capitol at a nuclear energy discussion board hosted by PowerHouse Texas, a nonprofit that promotes vitality innovation.
However, he added, “Texas is going to have to decide: At what level of risk is it prudent for taxpayer dollars to be risked?”
The primary new reactors could be commercially prepared inside 5 years, he mentioned; most are 10 to twenty years away.
Dozens of proposed new reactor designs promise improved effectivity and security over conventional fashions with much less hazardous waste. Whereas present nuclear reactors use cooling programs full of water, so-called “advanced” reactor designs use alternate options like molten salt or metallic. It allows them, in concept, to function at the next temperature and decrease stress, rising the vitality output whereas reducing the dangers of leaks or explosions.
Earlier than it may be constructed, every design is extensively reviewed by the Nuclear Regulatory Fee in a yearslong course of to make sure they meet security necessities.
“We understand how much work we’re facing and getting that done means finding every appropriate efficiency in our reviews,” mentioned Scott Burnell, public affairs officer for the NRC.
The fee can be reviewing a allow software by Washington-based TerraPower, based by Invoice Gates in 2006, to construct a full industrial nuclear energy plant in Wyoming. It expects to obtain a building allow software for the X-energy reactor at Dow in Texas this 12 months, Burnell mentioned.
After building, the businesses would require a separate allow to function their initiatives. None have sought an working license for a sophisticated nuclear reactor, however Natura plans to file its software this 12 months.
For Towell, an Abilene native and the son of two ACU college members, this second was a decade within the making. In 2015 he based the NEXT Lab at ACU for superior nuclear testing, received a $3 million donation from a rich West Texas oilman in 2017, entered into partnership with the Power Division in 2019 and shaped the corporate Natura in 2020. Development completed in 2023 on NEXT’s shimmering new facility. And in 2024, the NRC issued a allow to construct the primary superior reactor at an American college.
What are superior nuclear reactors?
Rusty Towell, director of the Subsequent Lab, explains the molten salt expertise that will probably be employed in Abilene Christian College’s forthcoming nuclear analysis reactor to U.S. Sen. John Cornyn on April 2, 2024. The pit in entrance of them is the place the reactor will probably be put in.

Towell, a former teacher on the U.S. Naval Nuclear Energy College, mentioned these new initiatives signify the primary main development in American nuclear energy expertise in 70 years. Whereas layers and layers of security programs have been added, the essential reactor design has remained unchanged.
It makes use of a cooling system of circulating water to keep away from overheating, melting down and releasing its radioactive contents into the ambiance. The system operates at extraordinarily excessive stress to maintain the water in liquid state far above its boiling level. If circulation stops resulting from energy loss or malfunction, a buildup of stress may cause an explosion, because it did on the Fukushima Daiichi nuclear plant in Japan in 2011.
In distinction, new “advanced” reactor designs use alternate options to water for cooling, like liquid metallic or particular gases.
Natura’s design, like many others, makes use of molten salt. It’s not desk salt however fluoride salt, a corrosive, crystalline substance that melts round 750 levels Fahrenheit and stays liquid till 2,600 levels underneath common stress.
Because of this, the reactor can function at extraordinarily excessive temperatures with out excessive stress. If the system ruptures, it gained’t jettison a plume of steam, however as a substitute leak a molten sludge that hardens in place.
“It doesn’t poof into the air and drift around the world,” Towell mentioned. “It drips down to a catch pan and freezes to a solid.”
Fairly than strong gasoline rods, Natura’s design additionally makes use of a liquid uranium gasoline that’s dissolved into the molten coolant. In accordance with Towell, a former analysis fellow at Los Alamos Nationwide Laboratory, that decreases the quantity of radioactive waste produced by the reactor and makes it simpler to recycle.
The Kairos reactor design makes use of molten salt coolant with a whole lot of 1000’s of uranium gasoline “pebbles,” whereas the X-energy design makes use of gasoline pebbles with a gasoline coolant.
Critically, many new reactor designs are additionally small and modular. As a substitute of large, customized building initiatives, they’re meant to be inbuilt factories with meeting line effectivity after which shipped out on truck trailers and put in on web site. That may enable massive industrial services or knowledge facilities to function their very own energy sources unbiased from public electrical grids.
Natura president Doug Robison, a retired oil firm govt who labored 13 years as an ExxonMobil landman, mentioned small reactors might run oilfield infrastructure within the Permian Basin, from pumpjacks to compressor stations.
“By powering the oil and gas industry, which uses a tremendous amount of power for their operations, we’re helping alleviate the grid pressure,” he mentioned.
He additionally desires to energy new therapy crops for the big portions of wastewater produced every day within the Permian Basin. In January, Natura introduced a partnership with the state-funded Texas Produced Water Consortium at Texas Tech College aimed toward utilizing small reactors to purify oilfield wastewater, most of which is presently pumped underground for disposal.
“It always gets back to the funding”
The brand new reactor initiatives match into plans by state leaders to determine Texas as a worldwide chief of superior nuclear reactor expertise. In 2023, Gov. Greg Abbott directed the state’s Public Utility Fee to review the query and produce a report.
“Texas is well-positioned to lead the country in the development of ANRs,” mentioned the 78-page report, issued late final 12 months. “Texas can lead by cutting red tape and establishing incentives to accelerate advanced nuclear deployment, overcome regulator hurdles and attract investment.”
The report made a number of suggestions, and state lawmakers this 12 months have already filed payments to enact a number of of them, together with the creation of a Texas Superior Nuclear Authority and a nuclear allowing officer. Most importantly, the report additionally advisable two new public funds to help nuclear vitality deployment, together with one modeled after the Texas Power Fund, which was created in 2023 and made $5 billion in financing accessible for brand spanking new gasoline energy crops.
“When I talk to folks, it always gets back to the funding,” mentioned Thomas Gleeson, chair of the Public Utility Fee, throughout the PowerHouse discussion board. “All of those issues are somewhat ancillary to: How are we going to fund this?”
Gleeson mentioned builders will anticipate the state to place up at the least $100 million per challenge by way of public-private partnerships in an effort to assist cut back monetary threat.
“Given the load growth in this state that we’re projecting, if you want clean air and you want a reliable grid, you have to be in favor of nuclear,” he mentioned.
Critics of the plan oppose the usage of public cash on personal initiatives and fear about security.
“We don’t use tax dollars to fund a bunch of experimental and pie-in-the-sky designs that should be the responsibility of private industry,” mentioned John Umphress, a retired Austin Power program specialist who’s evaluating the nuclear efforts on contract for the patron advocacy group Public Citizen. “Nobody has really penciled out the cost because there’s still a lot of proof of concept that’s going to have to be pursued before these things get built.”
Umphress raised issues over supplies in growth to resist the astronomical temperatures and intensely corrosive qualities of molten salt coolants.
He additionally famous that the U.S. nonetheless lacks a everlasting repository for nuclear waste following many years of unsuccessful efforts. Most waste at the moment is saved on web site in specialised interim services at nuclear energy crops, which wouldn’t be potential if small reactors had been deployed to particular person industrial initiatives.
“That’s the big issue that we still haven’t solved, but it’s not stopping some of these developers from pushing forward with their designs,” he mentioned. “They’re hoping the federal government will take ownership of the waste and be responsible for its storage and disposal.”
Throughout the PowerHouse discussion board, officers expressed hope that the personal sector would develop an answer after new reactor initiatives create demand for waste disposal.
The vitality proving floor
These reactor initiatives are nonetheless a few years away. To date, the NRC has solely licensed superior reactor building for college analysis. Subsequent it should challenge permits for bigger industrial reactors earlier than they are often deployed.
Maybe the most important early deployment of business superior reactors is about to happen at Texas A&M College. In February, the varsity introduced that 4 firms had dedicated to put in their industrial reactor designs at a brand new 2,400-acre “Energy Proving Ground” close to its School Station campus.
The positioning is an outdated Military air base, presently house to automobile crash take a look at services and a sophisticated warfare growth advanced.
The college will construct infrastructure there and assist streamline allowing for the reactor initiatives, mentioned Joe Elabd, vice chancellor for analysis on the Texas A&M System. The college is requesting $200 million in state appropriations to assist develop the location, he mentioned.
“We’re providing a little bit more of a plug-and-play site for these companies, as opposed to them going to a true greenfield and having to do everything for themselves,” he mentioned.
Reactors on the location will probably be linked to Texas’ electrical girdle, Elabd mentioned.
A&M started searching for proposals from firms to construct on the web site final August, and a panel of college specialists chosen the 4 finalists, which embrace Natura and Kairos.
A Kairos spokesperson, Christopher Ortiz, mentioned the corporate is constructing a producing facility in Albuquerque, New Mexico, which can produce the reactors deployed to Texas A&M. He mentioned the corporate is presently working to establish websites for future industrial reactors, evaluating components like workforce availability, present infrastructure and neighborhood help.
“The Texas A&M site presents a unique opportunity to site multiple commercial power plants in one location, which makes it particularly attractive,” he mentioned.
The positioning can even embrace Terrestrial Power, a Canadian firm. And it’ll embrace Aalo Atomics, a 2-year-old investor-funded startup that’s presently constructing a 40,000-square-foot reactor manufacturing facility in Austin, which it plans to unveil in April.
Greater than modular reactors, Aalo plans to supply complete modular energy crops, referred to as Aalo Pods, together with a number of reactors, a turbine and a generator, that are designed to be put in at knowledge facilities.
“It’s made in the factory, shipped to the site and assembled like LEGOs,” mentioned Aalo CEO Matt Loszak.
He estimated 5 to 10 years for deployment on the A&M web site however mentioned that relied on continued monetary help from traders. Aalo is growing its reactor design on the Division of Power’s Idaho Nationwide Laboratory, a 70-year-old nationwide nuclear analysis middle.
However Loszak, a former software program engineer from Canada, determined to find his manufacturing facility in Texas, he mentioned, to be near large incoming vitality calls for and to benefit from the state’s business-friendly strategy to regulation.
“Politicians here are really pro-nuclear, they want to see nuclear get built, and that’s not the case in other places across the country,” he mentioned. “From a regulatory and permitting perspective, it’s a great place to build stuff.”
