New ultrasonic testing equipment being used by the Department of Energy’s Idaho Cleanup Project (ICP) to confirm the integrity of thousands of legacy waste drums is saving taxpayers tens of millions of dollars, the DOE’s Office of Environmental Management announced.

The technology allows ICP personnel to inspect the thickness transuranic waste drums held in storage at the DOE’s Idaho National Laboratory Site, ensuring they meet Department of Transportation minimum thickness requirements to be shipped for disposal at the Waste Isolation Pilot Plant in New Mexico. According to DOE-EM, if drums meet the DOT thickness requirements, they can be loaded directly into shipping casks without the need for an expensive overpack container, leading to a minimum cost savings of $26 million.

BWX Technologies Inc. has purchased about 97 acres of land in an Oak Ridge, Tenn., industrial park where the company expects to build a uranium enrichment facility using a technology called DUECE, or, Domestic Uranium Enrichment Centrifuge Experiment. DUECE was developed at Oak Ridge National Laboratory to provide enriched uranium for the Department of Energy’s National Nuclear Security Administration, and BWXT is several months into a yearlong engineering study to evaluate options for deploying a centrifuge pilot plant using DUECE.

Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.

TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Oak Ridge National Laboratory has successfully removed legacy radioactive waste stored for more than five decades, marking a significant cleanup milestone. The Oak Ridge Office of Environmental Management (OREM) and cleanup contractor UCOR processed and shipped highly radioactive source material, including radium-226 and boron, out of state for permanent disposal.

A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”

By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

Leaders in Ghana announced recently that the country has a “framework agreement” with U.S.-based companies NuScale and Regnum Technology Group.

The announcement made by Stephen Yamoah, executive director of Nuclear Power Ghana, was reported by the Ghana News Agency on March 31. He also said Japanese firms will be working in partnership with NuScale and Regnum on the small modular reactors while the China National Nuclear Corporation will construct a large reactor.

The University of Missouri announced today that it has signed a $10 million contract for the initial design phase of the $1 billion-plus state-of-the-art NextGen MURR research reactor project.

The Federal Energy Regulatory Commission has doubled down on its rejection of an interconnection service agreement (ISA) between Amazon Web Services and Talen Energy in Pennsylvania.

Plans to bring a university research reactor like no other to the campus of the University of Illinois at Urbana-Champaign (UIUC) were punctuated last fall by the news that Ultra Safe Nuclear, the developer of the gas-cooled reactor technology selected for the Illinois Microreactor Project, had declared bankruptcy.

Researchers at GE Hitachi Nuclear recently completed a successful test on potential new building blocks made of steel-concrete composite.

The Defense Innovation Unit announced April 10 next steps in the Advanced Nuclear Power for Installations (ANPI) program, launched in 2024 to deploy microreactor nuclear systems for increased power reliability at select military locations.

Jarrell

Roger Jarrell will lead the Department of Energy’s Office of Environmental Management as the new principal deputy assistant secretary. Jarrell, who served in the office during the first Trump administration, was named DOE-EM senior advisor in January. Prior to that, he served as the general counsel and previously was the government and stakeholder interface at DOE cleanup contractor UCOR, of Oak Ridge, Tenn.

Jarrell takes over the assistant secretary position, listed on DOE-EM’s organizational chart as EM-2, from Dae Chung, a long-serving DOE-EM executive who was tapped by the Trump administration in March to lead the office as acting principal deputy assistant secretary following the departure of Candice Robertson, who had led the office since June 2024.

Mike Mlynarek believes in this expression: “In the end it will be OK; and if it’s not OK, it’s not the end.”

As the site vice president at Palisades nuclear power plant in Covert Township, Mich., Mlynarek is overseeing one of the most exciting projects in the United States nuclear power industry. If all goes according to plan, Holtec’s Palisades plant will be splitting atoms once again by the end of 2025 and become the first U.S. nuclear facility to restart after being slated for decommissioning.

Southern Nuclear recently loaded nuclear fuel with uranium-235 enriched up to 6 percent—higher than the usual 3–5 percent enrichment—into Vogtle-2 to test it through irradiation.

Brandon Williams appeared before the U.S. Senate’s Committee on Armed Services this week to answer questions on how he would lead the Department of Energy’s National Nuclear Security Administration, if confirmed for the job.

President Donald Trump announced Williams as his pick for the NNSA role in January. Energy Secretary Chris Wright said he was personally involved in the selection of Williams for the role, telling the Exchange Monitor in January, “He’s a smart, passionate guy [who] wants to defend our country.”

The Department of Energy has announced its first round of conditional commitments to provide high-assay low-enriched uranium to five U.S. nuclear developers. According to the DOE, the delivery of HALEU will support the commercialization of advanced nuclear technologies, aiming to deliver secure, affordable, and reliable energy to Americans.

Subsequent license renewal (SLR) authorizes nuclear power plants to operate for an additional 20 years beyond the 60 years of the initial license (years 1–40) and the first license renewal (years 41–60). NUREG-2191, Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR), and NUREG-2192, Standard Review Plan for Review of Subsequent License Renewal Applications (SRP-SLR), were issued in July 2017 and provide guidance for generic evaluation of plant aging management programs and reviews of SLR applications, respectively, by Nuclear Regulatory Commission staff.

The first SLR application was submitted to the NRC for review in January 2018. A total of 10 additional SLR applications addressing 20 operating units have been submitted to the NRC. Nine operating units have been approved by the NRC, and 13 units are under review. These 22 units do not have any issues, including operating experience issues, precluding them from achieving a renewed license.

A bill that would create a nuclear energy task force in Delaware has passed the state Senate and is now being considered in the House of Representatives.

When Exelon Generation shut down Three Mile Island Unit 1 in September 2019, managers were so certain that the reactor would never run again that as soon as they could, they had workers drain the oil out of both the main transformer and a spare to eliminate the chance of leaks. The company was unable to find a buyer because of the transformers’ unusual design. “We couldn’t give them away,” said Trevor Orth, the plant manager. So they scrapped them.

Now they will pay $100 million for a replacement.

The turnaround at the reactor—now called the Crane Clean Energy Center—highlights two points: how smart Congress was to step in with help to prevent premature closures with the zero-emission nuclear power production credit of 0.3 cents per kilowatt-hour (only two years too late), and how expensive it is turning out to be to change course.

The Canadian Nuclear Safety Commission has announced its approval for Ontario Power Generation to construct a General Electric Hitachi BWRX-300 small modular reactor at its Darlington site in Clarington, Ontario.
