The Energy Department says a small nuclear reactor under development at a national lab has reached a crucial milestone that could allow it to produce electricity within a few years.

The microreactor being developed by Antares Nuclear Inc. at the Idaho National Lab reached “criticality” on Thursday, Energy Secretary Chris Wright said. The milestone occurs when a nuclear reactor achieves a self-sustaining chain reaction capable of producing a steady release of energy.

Antares is the first private company to bring an advanced reactor to criticality under a pilot program begun last year by the Trump administration meant to supercharge nuclear energy production in the U.S. The demonstration was conducted in partnership with the Energy Department and other contractors with support from the U.S. Army.

The Trump administration is in “active dialogue” on creating a petroleum reserve in California, Energy Secretary Chris Wright told POLITICO on Friday, a move that would boost oil infrastructure in the state and undermine Democratic Gov. Gavin Newsom’s bid to shrink the state’s fossil fuel footprint.

A June 2 document that lawyers for Sable Offshore Corp., which owns a trio of oil platforms off the California coast, sent to the Energy Department and seen by POLITICO shows the company has proposed a West Coast Strategic Petroleum Reserve “in response to the inquiries made by the Trump administration and in the furtherance of Sable’s ongoing discussions with the Department of War for the supply of oil and gas to California.”

Urenco USA, operator of the only U.S. commercial-scale uranium enrichment facility, will expand low-enriched uranium (LEU) capacity at its National Enrichment Facility (NEF) in Eunice, New Mexico, by nearly 50% through a privately funded, multibillion-dollar investment that includes construction of a new enrichment plant. The project will add 2.1 million separative work units (SWU) of new enrichment capacity.

The expansion, announced June 2, will install up to 24 gas centrifuge cascades at the licensed New Mexico site. While construction is slated to begin at the new plant in 2029, the first cascades are scheduled to begin production in 2032, and additional cascades are slated for installation through 2036. The NEF site is already licensed by the Nuclear Regulatory Commission (NRC) for up to 10 million SWU of capacity—well above the projected buildout, Urenco told POWER.

The Trump administration on Friday auctioned off rights to drill in a pristine wildlife refuge in Alaska, but the lease sale attracted only two bidders on a few tracts of land.

Of the about 60 tracts of land opened up for leasing by the Trump administration, only five received bids. Only Hex Energy and the state-owned Alaska Industrial Development and Export Authority bid on tracts.

Overall, the lease sale netted about $3.7 million, half of which will go to the state of Alaska.

large data center

This piece was initially published in the MS Biz Journal.

With the AI and data boom underway, electricity has become the top economic infrastructure for growth. Electricity has long been foundational to our society, powering our homes and businesses, but now, it is the primary infrastructure on which the digital economy, advanced manufacturing and an American industrial resurgence depend.

In an era of data centers, AI, and electrified production, the ability to generate and deliver large quantities of reliable power is quickly becoming the difference between regions that grow and those that struggle.

The unprecedented electricity demand growth rate has critics claiming electricity bill increases will be the result of it all. Such claims ignore how electric systems trended prior to 2020, especially in Mississippi. From 2000 to 2020, U.S. electricity consumption only increased 11%, and in Mississippi, the growth was only about half that. Over the next 10 years, U.S. electricity demand growth is projected at an astronomical 40%.

Electricity is a capital-intensive business. When we pay for kilowatt hours, what we’re actually paying for is the vast infrastructure required to make and deliver it—generation plants, high-voltage transmission lines, substations, local distribution lines, transformers and a specialized workforce. A system is built for growth, so when there is little or no growth in sales of kilowatt hours, those same kilowatt hours, or us consumers, must bear the increasing costs of maintenance and replacement.

That’s why data centers can be ideal additions to an electric system and good for the other customers on the system. When more electricity is flowing over the same lines, the fixed costs of the entire system are now spread over many more kilowatt hours, just by adding one or several large customers.

That’s precisely what’s happening with Mississippi Power Company serving the Compass Data Center under construction in Meridian. Compass will be consuming surplus electric capacity already available on Mississippi Power’s system. By picking up such a large-load customer in Compass, existing Mississippi Power customers will benefit in the future as costs are spread over more kilowatt hours.

In the case of Amazon Web Services’ (AWS) multiple campuses in Canton, Ridgeland, Clinton and Vicksburg and AVAIO in Brandon, all within Entergy Mississippi’s service area, there are unprecedented infrastructure additions underway to meet the new capacity needs but still to the benefit of other customers on the system.

Three new natural gas generating plants are being in Greenville, Ridgeland and Vicksburg. Plants in Greenville and Vicksburg were 50+ years old needing replaced, where AWS is picking up a huge share of the cost while paying for their added electric power needs. Existing Entergy customers will benefit for decades from the new, more efficient plants, at a far lower cost than what would have been without the large industrial customers.Due to the data projects, Entergy recently announced a projected $5 billion in savings over 20 years to existing customers across their multi-state system with $2 billion of that to Mississippi customers. Further, Entergy Mississippi announced a $300 million upgrade to system reliability and storm strengthening efforts entirely due to new revenue from data centers.

Considering the path electric systems were on just a few years ago, large-load data centers are just the thing needed to take pressure off of rising electricity rates. Over the last few years, you may have noticed, electricity rates have risen, but why? Not data centers. Not higher natural gas prices. Inflation. The cost of just about everything rose much more sharply than normal from 2022-2025, and electricity followed.

Still, Mississippi comes in with electricity rates 16% lower than the national average. We want to keep it that way, right? The best way to do that is by growing the system, making the pie bigger and spreading costs across a growing consumer base. By the way, the same principle applies to taxes and public revenue, of which data center development can be a tax windfall, especially locally.

The benefits of electricity-based development are just too great to turn away, and to turn away likely means to fall behind. Whether data centers or advanced manufacturing, forward thinking and more energy development could continue to pay off for years to come.

A year ago, President Donald Trump issued four executive orders aimed at restoring America’s lost global leadership in nuclear energy—a worthy goal. Over 80 years ago, the United States unlocked the secrets of atomic fission through the Manhattan Project and then, pursuant to President Dwight D. Eisenhower’s historic Atoms for Peace vision, harnessed that awesome power to benefit humanity through abundant clean energy.  

In the 1950s, Admiral Hyman Rickover launched the world’s first nuclear-powered submarine, the USS Nautilus. The nuclear Navy laid the groundwork for the world’s first commercial nuclear reactor at Shippingport, Pennsylvania. By the late years of the Cold War, over 300 US commercial and naval reactors were operational, and the United States was the world’s unquestioned nuclear leader. US designs underpinned the reactor deployments in Europe and Asia.  The United States also dominated the world market in supplying the enriched uranium required by most of the world’s reactors.

The U.S. has announced a new partnership with Japan on science and artificial intelligence.

Energy Department Under Secretary for Science Darío Gil told reporters Thursday that each country would invest $500 million in the joint venture.

“This is the defining moment for the next era of science,” he said. “We’re linking our brightest minds and the most advanced tools — both in the U.S. and in Japan, and around the world — into a cohesive engine of discovery.”

The announcement comes as part of the administration’s “Genesis Mission”, which seeks to advance the use of AI for scientific research.

The Trump administration’s push to expand oil and gas development in Alaska faces a new test Friday, with the latest lease sale set for the Arctic National Wildlife Refuge.

Opponents of drilling in the refuge’s coastal plain have pointed to a lack of industry interest in the prior two sales held there and ongoing changes in Alaska’s arctic region due to climate change as proof the region should be off-limits to drilling. But supporters of drilling see the coastal plain, which is roughly the size of Delaware, as a potential untapped resource that could boost U.S. oil production and generate new revenue and jobs.

America’s geothermal energy sector sits on a paradox. The technology is ready, the reserves are vast, and the demand for clean, reliable power has never been higher, but outdated federal regulations act as a bottleneck on projects for years before they can ever deliver electricity. Two bills recently passed by the U.S. House—H.R.5631, the Geothermal Energy Advancement Act, and H.R.1687, the CLEAN Act—take direct aim at this regulatory dysfunction. Together, they represent a consequential step toward realizing the full extent of the geothermal opportunity as the legislation now moves to the Senate for consideration.

The scale of that geothermal potential is hard to overstate. The Department of Energy estimates that U.S. geothermal reserves could produce up to 300 gigawatts of electricity. That potential represents over 20% of all capacity on the U.S. grid and is equivalent to powering New York City more than 50 times over. The technology also produces near-zero operational carbon emissions and delivers round-the-clock electricity to residential and commercial customers.

What is holding it back is not the technology, but a failure of regulatory governance.

Duplicative permitting requirements, inconsistent federal lease sales, and numerous other bureaucratic challenges have created a system that frustrates serious developers and rewards inaction. Projects stall under procedural costs; many are never financed because of the lack of a predictable, regulatory runway. Reforming these regulatory failures will provide the consistency and speed the market needs to invest and scale this industry with confidence.

The Geothermal Energy Advancement Act tackles the permitting side of this equation. During exploration and development, federal environmental review requirements can trigger as many as six separate interventions. These impose a significant administrative burden on under-resourced permitting offices, particularly for categories of low-risk exploration activity that rarely surface meaningful environmental impacts. The bill takes targeted action to exclude such activities from reviews, while reserving full environmental scrutiny for more disruptive stages of development. It also directs fees collected for permitting and leasing services back into the Interior offices doing that work. This cost-recovery method is already used for oil, natural gas, solar, and wind development, making it a proven way to give permitting staff the resources they need to move efficiently. Additionally, the bill adds an appointed Geothermal Ombudsman tasked with facilitating internal and external coordination, including for permitting, across the Bureau of Land Management and its field offices.

The CLEAN Act addresses a separate but equally critical failure before permitting even occurs: inconsistent federal lease sales. Infrequent and unpredictable auctions of federal lands have historically created an opportunity for rich, speculative bidders to drive up lease prices. This raises the cost and risk of exploration for developers who actually intend to build. Requiring annual lease sales and timely replacement sales—two key provisions of the CLEAN Act—provides discipline and consistency to the leasing process. The result is a market more accessible to serious developers and less hospitable to speculation.

The case for reform is straightforward. American economic competitiveness hinges on the availability of reliable, affordable electricity. Geothermal has the potential to deliver it, and America leads in its development for now. But that leadership is not guaranteed. Scaling deployment requires the federal government to modernize regulations that have not kept pace with the technology. Following the House’s decisive action on these two bills, the Senate should maintain this momentum and catapult both pieces of legislation to the Oval Office.

Since 1998, the federal government has paid nuclear reactor owners more than$10.6 billion in court-ordered damages over a broken contract of its own making. The tab grows by roughly $2 million a day, and total federal exposure may eventually reach $39.2 billion. The cause isn’t a safety failure or a market collapse but rather political failures.

The Nuclear Waste Policy Act of 1982 imposed a legal obligation on the federal government to take custody of commercial used nuclear fuel by January 31, 1998, and to dispose of it permanently. The law designated Yucca Mountain in Nevada as the repository site, a choice the state’s leaders fought from the start. However, residents and local politicians in Nye County, home to Yucca Mountain, have consistently voiced support for the licensing process. 

Even so, in response to sustained opposition from Nevada’s congressional delegation, the Obama administration moved to withdraw the Yucca Mountain license application in 2010. The Government Accountability Office (GAO) later concluded that the decision rested on no safety or technical finding against the site, but was driven by politics rather than science. 

No replacement plan was offered. The fuel stayed where it was, at reactor sites never designed for long-term storage. Ratepayers had already paid into a federal fund for disposal and now had to spend their own money to store the waste the government was supposed to take care of. The courts have ordered the government to cover those costs, meaning the bill for taxpayers keeps growing as long as Washington fails to live up to its obligation for a long-term storage option.

In the meantime, the private sector is helping to address the change. Holtec International and Interim Storage Partners (ISP) each secured licenses from the Nuclear Regulatory Commission for privately funded interim storage facilities. Both had the support of their host communities and cleared federal regulatory review. State-level political challenges then worked their way into federal court, and the Fifth Circuit Court of Appeals vacated ISP Texas’slicense in August 2023 and Holtec New Mexico’s license in March 2024.

In June 2025, the Supreme Court held that the challengers lacked standing to contest the NRC’s licensing decision, thereby clearing the way for both licenses. But the Court decided the case on procedural grounds and left the underlying question of NRC’s statutory authority unsettled. That unresolved question is precisely why a legislative fix is still needed. Holtec canceled its New Mexico project anyway in October 2025, citing an untenable path forward amid continued state opposition. That a fully licensed project could still collapse is clear evidence that the current framework is too fragile.

The Trump administration is steering policy in the right direction. In May 2025, President Trump signed executive orders directing DOE to evaluate the transfer of commercial used fuel to a government-owned, privately operated reprocessing facility and to develop a national policy for used fuel management. That policy report was due in January 2026, but it has not been publicly released.

Two steps could turn this into a concrete policy solution. The first is amending the 1982 law to establish a stable statutory footing for waste repositories. For example, a consent-based siting framework requiring affirmative agreement from the host state and community, with the federal licensing decision as the final determination and no legal avenue for outside actors to relitigate after the fact. 

The bipartisan Nuclear Waste Administration Act of 2024, introduced by Representatives Pfluger and Levin, proposed exactly this framework, drawing on recommendations from the Blue Ribbon Commission on America’s Nuclear Future, the National Academies of Sciences, and the GAO. Holtec and ISP had the community support that the model requires. What they lacked was a legal foundation stable enough to survive litigation.

The second is for Congress to press the administration to release the overdue spent fuel policy report and use it as a basis for updating the 1982 law. The administration has framed the problem correctly. Congress can add permanence with a statutory fix that future administrations cannot reverse. 

Any future nuclear buildout needs a real solution for spent fuel. Ultimately, comprehensive policy reform should shift full responsibility for the private sector to pay for and manage spent fuel. The private sector has shown it is ready to build one, and the administration has shown a willingness to address the problem. Congress should provide a durable foundation to help those solutions stick.
