The Canadian Medical Isotope Ecosystem, which is backed by the Canadian federal government’s Strategic Innovation Fund, has announced funding for a collaboration between Promation, Astral Systems, and McMaster University to establish a proof-of-concept approach for a fusion reaction–based copper-67 production process with automated postirradiation isotope separation and purification.

Sweden-based advanced reactor developer Blykalla has applied to build a site in its home country that would feature six lead-cooled small modular reactors. The 330-MWe facility would house a half-dozen 55-MWe Sealer reactors, which the company said are designed for hyperscalers and energy-intensive industries.

At the end of April, TerraPower announced that it had officially begun construction on its Natrium power plant in Kemmerer, Wyo.—one of the two full-scale demonstration projects in the Department of Energy’s Advanced Reactor Demonstration Program.

Now, the second ARDP-backed demonstration project, which aims to see the deployment of X-energy’s Xe-100 at a Dow chemical facility, has reached a new milestone of its own. On May 18, X-energy announced that the Nuclear Regulatory Commission has completed its environmental assessment of the proposed Long Mott Generating Facility and issued a finding of no significant impact (FONSI).

In response to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” the NRC is proposing sweeping changes to its rules governing the use of nuclear materials that are widely used in industry, medicine, and research. The changes would amend NRC regulations for the licensing of nuclear byproduct material, some source material, and some special nuclear material.

As published in the May 18 Federal Register, the NRC is seeking public comment on this proposed rule and draft interim guidance until July 2.

The Maine Maritime Academy (MMA) is set to become the first maritime academy in the United States to offer a major in nuclear engineering technology. The college characterized it as “an important step in addressing workforce needs and advancing clean energy solutions” in a LinkedIn post announcing the major.

Oak Ridge National Laboratory announced the completion of a set of experiments measuring the viscosity and thermal conductivity of several uranium-bearing molten salts, filling in gaps that could help with the development of molten salt reactors.

The noticeable exuberance within the nuclear community as a whole appears to have spilled over into the waste management sphere as well, judging from the 2026 Waste Management Conference, held March 8–12 in Phoenix, Ariz., and sponsored by Waste Management Symposia.

The theme of this year’s conference was “Efficient and Innovative Nuclear Materials and Technology Solutions,” and many of the scheduled panels and technical sessions revolved around how nuclear growth and technological advancements are affecting the back end of the fuel cycle, as well as how the cleanup of legacy sites is enabling new nuclear development.

NextEra Energy is set to acquire Dominion Energy, the two utilities announced earlier today in an approximately $67 billion merger that will alter the energy landscape—including for nuclear power—in the United States.

The Department of Energy’s Office of Environmental Management has received concurrence from regulators that Tank 14 at the Savannah River Site has reached preliminary cease waste removal (PCWR) status after radioactive liquid waste was successfully removed from the tank. PCWR is a regulatory milestone in the closure of SRS’s old-style waste tanks, which were built in the 1950s to store waste generated by the chemical separations of plutonium and uranium.

The University of Missouri’s President’s Distinguished Lecture Series featured a talk by William D. Magwood IV, director general of the OECD Nuclear Energy Agency and a former NRC commissioner, on May 13 at the Columbia campus’s Bond Life Sciences Center. Magwood speech was titled “The Next Nuclear Energy Era: Opportunities and Challenges.”

Lawmakers in Congress have introduced a pair of bills this month targeting different aspects of nuclear construction, with one proposal focusing on construction material and the other on tax credits.

For 45 years, Duane Arnold Energy Center operated in Linn County, Ia., near the town of Palo and just northwest of Cedar Rapids. The facility, owned by NextEra Energy, was the only nuclear power plant in the state.

In August 2020, a historic derecho swept across eastern Iowa with winds approaching 140 miles per hour. Damage to the plant’s cooling towers accelerated a shutdown that had already been planned, and the facility entered decommissioning soon after, with its fuel removed in October of that year. Iowa’s only nuclear plant had gone off line.

Today the national energy landscape looks very different than it did just six short years ago. Electricity demand is rising rapidly as data centers, artificial intelligence infrastructure, advanced manufacturing, and electrification expand across the country. Reliable, carbon-free baseload power has become increasingly valuable. In that context, Linn County has approved the rezoning necessary to support the recommissioning and restart of Duane Arnold and is actively supporting NextEra’s efforts to secure the remaining state and federal approvals.

The project team for the world’s largest operational tokamak, JT-60SA, has announced that it is getting ready to resume operations. The machine has been undergoing upgrades since 2024, with testing of newly installed equipment occurring since February 27.

The Nuclear Regulatory Commission will hold a regulatory conference Tuesday, May 19, with Vistra Operations Company officials to discuss a preliminary “white” safety finding at Comanche Peak-2.

Eight companies will collectively receive more than $94 million in cost-share funding to expedite the near-term deployment of small light water modular reactors, the Department of Energy announced Thursday.

Indianapolis-based reactor development start-up First American Nuclear (FANCO) announced on May 13 that it has entered into a strategic alliance with Montreal-based nuclear engineering company AtkinsRéalis.

Together, the companies now plan to jointly develop, test, and license FANCO’s EAGL-1 reactor design. For FANCO, the agreement comes as a chance to bring in a partner with decades of experience in nuclear project development. For AtkinsRéalis, the partnership provides the opportunity to establish a presence in Indiana.

Utah State University and Battelle Energy Alliance, an Idaho National Laboratory contractor, have signed a memorandum of understanding, committing to a Strategic Understanding for Premier Education and Research (SUPER) agreement, which formalizes and expands the university’s collaboration with INL.

Last month, all five commissioners of the Nuclear Regulatory Commission went before the U.S. House Committee on Energy & Commerce’s Energy Subcommittee to discuss the agency’s fiscal year 2027 budget and share priorities and activities key to the agency.

On Wednesday, the five took the NRC’s $892.3 million budget request for FY 2027 to the U.S. Senate’s Environment and Public Works Committee, where the focus shifted more toward the attrition of NRC employees and attempts to recruit and retain.

The Department of Energy’s Office of Environmental Management announced that its Oak Ridge Office of Environmental Management (OREM) is setting a new benchmark in cleanup progress at the Tennessee nuclear site—conducting demolition of two former Manhattan Project–era uranium enrichment facilities in a single year.

This week, the United States and South Korea have taken two steps toward deepening their nuclear partnership through two notable announcements. First, the majority-state owned Korea Hydro & Nuclear Power signed a memorandum of understanding with Birmingham, Ala.–based Southern Nuclear.
