Take steps on SNF and HLW disposal

With a new administration and Congress, it is time once again to ponder what will happen—if anything—on U.S. spent nuclear fuel and high-level waste management policy over the next few years. One element of the forthcoming discussion seems clear: The executive and legislative branches are eager to talk about recycling commercial SNF. Whatever the merits of doing so, it does not obviate the need for one or more facilities for disposal of remaining long-lived radionuclides. For that reason, making progress on U.S. disposal capabilities remains urgent, lest the associated radionuclide inventories simply be left for future generations to deal with.

In March, Rick Perry, who was secretary of energy during President Trump’s first administration, observed that during his tenure at the Department of Energy it became clear to him that any plan to move SNF “required some practical consent of the receiving state and local community.”1

Rafael Mariano Grossi, director general of the International Atomic Energy Agency, has shared his concerns about the Iran-Israel conflict with the agency’s board of directors.

“Military escalation threatens lives, increases the chance of a radiological release with serious consequences for people and the environment and delays indispensable work towards a diplomatic solution for the long-term assurance that Iran does not acquire a nuclear weapon,” Grossi said on June 16. “Consistent with the objectives of the IAEA and its statute, I call on all parties to exercise maximum restraint to avoid further escalation.”

Trump administration begins overhaul of the NRC

Hanson

Since the president's inauguration in January, the Trump administration has been on course to make big changes at the Nuclear Regulatory Commission to realize its goals of deregulation, energy dominance, and deployment of advanced reactors. Given the executive orders (EOs) and the work that the Department of Government Efficiency has done in cutting the federal workforce, it was a surprise that NRC commissioner Christopher Hanson was dismissed on Friday, according to a statement Hanson posted on his LinkedIn profile early Monday.

Hanson said in the post that President Trump terminated his position “without cause, contrary to existing law and long-standing precedent regarding removal of independent agency appointments.”

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.

Fedorchak

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:

DOE opens Milestone fusion pilot plant program to new companies and teams

June 12, 2025, 12:00PMNuclear News

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.

“Today’s Challenge, Tomorrow’s Promise”

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.

“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:
