U.S. utility Constellation Energy has signed a memorandum of understanding with ULC-Energy, an Amsterdam-based nuclear development company, to support deployment of a fleet of Rolls-Royce small modular reactors in the Netherlands.

Global Laser Enrichment (GLE) signed separate, nonbinding letters of intent in June with the two largest nuclear power operators in the United States—Constellation and Duke Energy—to assess potential nuclear fuel supply chain cooperation, including support for GLE’s deployment of laser enrichment technology in the United States. According to GLE president and chief commercial officer James Dobchuk, who delivered a presentation on June 7 at the World Nuclear Fuel Market Annual Meeting, the company’s baseline deployment schedule could be accelerated by about three years (under favorable market conditions) to supply the nuclear fuel market with uranium in a range of enrichment levels in 2027.

Using nuclear power technology to produce clean hydrogen is getting a visibility boost as the Department of Energy hosts a virtual three-day (June 6–8) Annual Merit Review and Peer Evaluation Meeting on the agency’s efforts to accelerate clean hydrogen production. On June 6, the DOE announced a notice of intent (NOI) to fund the Bipartisan Infrastructure Law’s $8 billion program to develop regional clean hydrogen hubs (H2Hubs) and the launch of a new Hydrogen Shot Incubator Prize that seeks “disruptive technologies” to reduce the cost of clean hydrogen production. That same day, Westinghouse Electric Company and Bloom Energy Corp. (a maker of solid oxide electrolyzer technology) announced a letter of intent to develop electrolyzers for use in the commercial nuclear power market and said they are “well positioned to support the U.S. Department of Energy’s developing hydrogen hubs.”

The United States has just 93 operating power reactors at this writing. The fleet last numbered 93 in 1985, when nuclear generation topped out at 383.69 TWh, less than half of the 778.2 TWh produced in 2021.

While the 93 reactors operating today have more capacity, on average, than in 1985, most of that increased productivity is down to operational improvements that pushed the fleet’s average capacity factor from just 57.5 percent in the three-year period 1984–1986 to near 90 percent by the early 2000s.

Kairos Power announced today that it has assembled an advanced nuclear development advisory consortium with four North American nuclear operators—Bruce Power, Constellation, Southern Company, and the Tennessee Valley Authority—dubbed Kairos Power Operations, Manufacturing and Development Alliance (Kairos Power-OMADA).

In a major change to its subsequent license renewal process, the Nuclear Regulatory Commission last week ruled that reviews of SLR applications must rely on a more extensive environmental analysis than that provided by the agency’s Generic Environmental Impact Statement for License Renewal of Nuclear Plants (GEIS). According to the ruling, the GEIS, properly understood, does not cover the SLR period.

Constellation, formerly Exelon Generation, owner and operator of the nation’s largest nuclear reactor fleet, announced this morning the completion of its separation from Exelon Corporation and its launch as a stand-alone, publicly traded company. Headquartered in Baltimore, Md., the new company began trading today on the Nasdaq Global Select Market under the symbol “CEG.”

Exelon announced last February that it had begun the effort to separate its utility businesses from its competitive power generation and customer-facing energy businesses.

Exelon Generation—owner and operator of the nation’s largest power reactor fleet—held an online event yesterday outlining the company’s business strategy as it prepares to separate from Exelon Corporation under the name Constellation. The separation is expected to become final on February 1.

Nuclear power plants are not quick to change. So when four utilities announce they will make room for shiny new electrolyzers and consider tweaking their business model, that’s news.

Nuclear power plants can leverage the energy stored in some of the world’s heaviest elements to generate the lightest: hydrogen. That is not news, but it casts an aura of alchemy over straightforward engineering. Amid the hype, and the hope of significant federal funding, it’s worth acknowledging that hydrogen has an industrial history over 100 years old. In the potential matchup of hydrogen and nuclear power, it’s nuclear that would be the newcomer.

The Nuclear Regulatory Commission has approved the indirect transfer of the licenses for 23 operating and five decommissioning reactors, as well as their associated independent spent fuel storage installations, from Exelon Corporation to a new company as part of a corporate restructuring, the agency announced yesterday.
