Published since 1959, Nuclear News is recognized worldwide as the flagship trade publication for the nuclear community. News reports cover plant operations, maintenance and security; policy and legislation; international developments; waste management and fuel; and business and contract award news.
Talen Energy Corporation and Amazon have signed an expanded power purchase agreement (PPA) whereby Talen agrees to supply electricity from its Susquehanna nuclear power plant for AI operations and other cloud technologies at Amazon Web Services’ data center campus next to the power plant.
In the fall of 2023, a small Zeno Power team accomplished a major feat: they demonstrated the first strontium-90 heat source in decades—and the first-ever by a commercial company.
Zeno Power worked with Pacific Northwest National Laboratory to fabricate and validate this Z1 heat source design at the lab’s Radiochemical Processing Laboratory. The Z1 demonstration heralded renewed interest in developing radioisotope power system (RPS) technology. In early 2025, the heat source was disassembled, and the Sr-90 was returned to the U.S. Department of Energy for continued use.
The Massachusetts Institute of Technology’s Plasma Science and Fusion Center (PSFC) has launched the Schmidt Laboratory for Materials in Nuclear Technologies (LMNT). Backed by a philanthropic consortium led by Eric and Wendy Schmidt, LMNT is designed to speed up the discovery and evaluation of cost-effective materials that can withstand extreme fusion conditions for extended periods.

North Dakota’s sole member of the U.S. House of Representatives, Republican freshman Congresswoman Julie Fedorchak, has introduced the Baseload Reliability Protection Act.
The bill aims to “amend the Federal Power Act to prohibit retirements of baseload electric generating units in any area that is served by a Regional Transmission Organization or an Independent System Operator and that the North American Electric Reliability Corporation [NERC] categorizes as at elevated risk or high risk of electricity supply shortfalls, and for other purposes.”
A summary of the legislation is available on Fedorchak’s House website.
Amendments: The Baseload Reliability Protection Act would amend the Federal Power Act in the following ways:
Eight companies were chosen to develop fusion pilot plant designs through the Department of Energy’s Milestone-Based Fusion Development Program just over two years ago. It wasn’t until June 2024 that the DOE announced that protracted negotiations over program metrics had been concluded. Now, two years on, the original eight are “making great progress,” according to Colleen Nehl, program manager for public-private partnerships in the DOE’s Office of Fusion Energy Sciences (FES). Nehl spoke during a June 4 webinar convened on short notice to discuss the latest fusion Milestone news: a fast-tracked opportunity for additional teams to access remaining Fiscal Year 2025 funding for the Milestone program.
Idaho National Laboratory this week signed a memorandum of understanding with the Missouri University of Science and Technology that highlights the joint commitment of the institutions to the Strategic Understanding for Premier Education and Research (SUPER) initiative.

The title for this year’s waste management issue of Nuclear News is, in my opinion, the perfect framing to consider spent fuel and waste management as we know it now and how we imagine it could look in the future. So, let’s break it down.
What really is “today’s challenge”? It’s certainly not safety. Since 1955, we have conducted more than 2,500 cask shipments without a single radiological release or incidence of harm to a member of the public. Despite what antinuclear evangelists (in dwindling numbers) might shriek, the industry’s record of storing and transporting used fuel is unassailable.
The lack of progress on a geologic repository isn’t necessarily a challenge to new nuclear development. We already have systems capable of storing used fuel assemblies for more than a century, proven technology with no moving parts.
The Nuclear Regulatory Commission is providing the opportunity to request a hearing on Dow Chemical Company’s application to construct a 320-MWe nuclear power plant at the company’s Seadrift site in Calhoun, Texas. Long Mott Energy, a wholly owned subsidiary of Dow Chemical, submitted its construction permit application to the NRC in March. It was accepted for review by the agency on May 12.
It’s a move that “brings to an end decades of dithering and delay, with the government backing the builders.” That’s how the U.K. government announced, with alliterative fanfare, its £14.2 billion (about $19.2 billion) investment in Sizewell C, where EDF Energy plans to build two 1,600-MWe EPRs.
Rolls-Royce SMR has emerged as the United Kingdom’s preferred bidder to build the country’s first small modular reactors following a two-year competition, the U.K. government announced June 10. Rolls-Royce SMR expects to build three SMRs with Great British Energy–Nuclear, subject to contracting later this year and regulatory approvals. Great British Energy–Nuclear will “aim to allocate a site later this year and connect projects to the grid in the mid-2030s.”
While attendance at the 2025 Waste Management Conference was noticeably down this year due to the ongoing federal retrenchment, the conference, held March 9–13 in Phoenix, Ariz., still drew a healthy and diverse crowd of people working on the back end of the nuclear fuel cycle, both domestically and internationally.

“As we enter the 21st century, the status of the U.S. nuclear energy industry is in flux, dependent on actions by industry, government, circumstance . . . and public opinion. Its renewal coincides with several initiatives taken by government and capitalized in particular ways by energy organizations, be they utilities, engineering firms, professional societies, educational institutions, national laboratories, trade organizations, and/or research and regulatory governmental branches . . . Nuclear fission has unleashed upon society benefits and cautionary tales that are currently being privately and publicly debated.”
These words, which I wrote almost a decade ago as part of my master’s thesis, are as true today as they were then. I have a long-standing relationship with the nuclear energy landscape. And so, as I reflect on my journey to and as your ANS president, there are some truths that have stood the test of time, serving as signposts that must remain in sight for the nuclear community:
In the weeks since President Donald Trump issued four nuclear energy–-focused executive orders (EOs), stakeholders across the nuclear industry weighed in on the plans and details. The American Nuclear Society convened an expert advisory group to study the directives and provide constructive input for the pending implementation.
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.
A group of nine former commissioners of the Nuclear Regulatory Commission sent a letter Wednesday to the chairs and ranking members of the Senate Environment and Public Works Committee and the House Energy and Commerce Committee, lending their support to efforts to remove mandatory hearings from the reactor licensing process. The move could speed up the new reactor licensing process by about three to six months and save millions of dollars.
The Department of Energy announced on June 5 that three companies—all of which are new to the Gateway for Accelerated Innovation in Nuclear (GAIN) voucher program—will receive vouchers to support their research on advanced fuels, materials, and sensors. The second round fiscal year 2025 vouchers will let the companies access specialized research facilities and expertise in the DOE’s national laboratory complex.
NuScale Power Corporation has opened another Energy Exploration (E2) Center—this one at George Mason University in Arlington, Va. Just last month, a NuScale E2 Center opened at South Carolina State University in Orangeburg, S.C. The newest E2 at George Mason is the company’s 11th center.

In late 2024, Canada’s Nuclear Waste Management Organization announced the selection of a site in northwestern Ontario for its deep geological repository for the country’s used nuclear fuel.
This is a major step in a plan that was first laid out in 2010. From the beginning, the plan had been clear that any selected site must be technically safe, must be accessible for fuel transportation, and must have informed and willing host communities.
By 2020, potential sites had been narrowed from an initial set of 22 communities that had indicated interest in learning more down to two specific sites.
My primary involvement was on the technical safety side. We wanted to know that we could safely build and operate the repository at the chosen site.
The Nuclear Regulatory Commission is conducting a special inspection at Constellation’s Quad Cities nuclear plant to review two events caused by battery issues. Neither event had any impact on public health or plant workers.
