Constellation Energy has announced an agreement with Commonwealth Edison (ComEd), Illinois’s largest electric utility, to power the latter’s 54 offices and metered facilities with locally produced nuclear energy, 24/7.

In the last few weeks of 2021, when it was clear that the Russian invasion of Ukraine had put this country’s uranium fuel supply in jeopardy, nuclear energy advocates lobbied hard to attach provisions to various pieces of “must-pass” legislation—such as the National Defense Appropriations Act (NDAA), the Ukraine Supplemental Appropriations Act, the Infrastructure Investment and Jobs Act, and the CHIPS and Science Act—to have the government get the ball rolling on new domestic uranium fuel production capacity. Four times they thought they had succeeded, that Congress was going to allocate enough money to start the United States on the road to a secure supply of reactor fuel, including the higher-enriched fuel needed for advanced reactors.

When Ken Petersen is asked what he sees as the biggest challenges facing nuclear today and in the future, he immediately turns the question around. The 69th president of the American Nuclear Society prefers to focus on the positives of nuclear power instead of dwelling on the biggest challenges facing nuclear’s future prospects. That’s because there’s a lot to celebrate within the nuclear community—especially recently.

Most everything is trending up—from advanced technologies such as SMRs and microreactors to the promise of fusion energy to new ways of creating medical isotopes to progress in space exploration. “There’s huge momentum for nuclear right now,” Petersen said. “We're getting support from the environmentalist community and from legislation. I see it as a huge opportunity for us to continue to grow. It’s an exciting time. And it’s not just the U.S. It’s worldwide, too.”

Officially established on November 15, 2021, with the signing of the $1.2 trillion Infrastructure Investment and Jobs Act—aka the Bipartisan Infrastructure Law, or BIL—the Department of Energy’s Civil Nuclear Credit Program was designed to give owners/operators of commercial U.S. reactors the opportunity to apply for certification and competitively bid on credits to help support the continued operation of economically troubled units. Finally, the federal government, and not just certain farsighted state governments, would recognize nuclear energy for its important grid reliability and decarbonization attributes.

Constellation Energy, operator of the largest U.S. reactor fleet, is acquiring NRG Energy’s 44 percent ownership stake in the South Texas Project nuclear plant, the Baltimore, Md.–based company announced this morning.

The Nuclear Energy Institute—along with Constellation, Energy Harbor, PSEG, and Vistra—submitted a 19-page letter on May 24 to the Treasury Department and Internal Revenue Service, taking issue with April 10 comments to those agencies from the Clean Air Task Force (CATF) and Natural Resources Defense Council (NRDC) concerning the Inflation Reduction Act’s clean hydrogen production tax credit (Internal Revenue Code sec. 45V). (The Treasury and the IRS released a notice last November requesting public input on the credit’s implementation.)

Helion Energy, based in Everett, Wash., today announced an agreement to use its first fusion power plant to provide electricity to Microsoft. Constellation, which operates 21 commercial nuclear reactors in the United States, will serve as the power marketer and will manage transmission for the project.

In the new year, ANS launched Trustees of Nuclear, a corporate partnership program ANS executive director/chief executive officer Craig Piercy announced in the January issue of Nuclear News (p. 25). The goal of Trustees of Nuclear is to directly support ANS’s programs aimed at improving nuclear literacy, like the Society’s K-12 nuclear STEM activities, public engagement, and discussions with policymakers. As the main professional organization for the whole nuclear discipline, ANS is in a unique position to unite leaders in the nuclear community to focus on these long-term programs and help the country realize the full potential of the atom.

The naturalist John Muir is widely quoted as saying, “When we try to pick out anything by itself, we find it hitched to everything else in the Universe.” While he was speaking of ecology, he might as well have been talking about nuclear fuel.

At the moment, by most accounts, nuclear fuel is in crisis for a lot of reasons that weave together like a Gordian knot. Today, despite decades of assertions from nuclear energy supporters that the supply of uranium is secure and will last much longer than fossil fuels, the West is in a blind alley. We find ourselves in conflict with Russia with ominous implications for uranium, for which Russia holds about a 14 percent share of the global market, and for two processes that prepare uranium for fabrication into reactor fuel: conversion (for which Russia has a 27 percent share) and enrichment (a 39 percent share).

“Right now, our country is deficient in nearly every aspect of the fuel cycle. This must change and it must change quickly,” said Sen. Joe Manchin (D., W.V.), chairman of the Senate Committee on Energy and Natural Resources (ENR), as he opened a Full Committee Hearing to Examine the Nuclear Fuel Cycle on March 9. “Whether it is uranium mining, milling, conversion, enrichment, nuclear fuel fabrication, power generation, or nuclear waste storage and disposal, there is much work to be done, starting with conversion and enrichment. Simply put, Russia dominates the global market, representing nearly half of the international capacity for both processes.”

Constellation Energy has announced that it intends to invest $800 million in new equipment at the Braidwood and Byron nuclear plants in Illinois to raise their combined output by a total of about 135 MW.

Constellation Energy, owner and operator of the nation’s largest reactor fleet, will ask the Nuclear Regulatory Commission to extend the operating licenses of the Clinton and Dresden reactors by 20 years, the company announced Monday, adding that it expects to file license applications with the agency in 2024.

Collecting belt buckles from nearly every nuclear power plant in the U.S. wasn’t the goal for Don Hildebrant when he obtained his first one. Over time, it just turned out that way.

One day years ago, Hildebrant came across a buckle from the nuclear plant where he worked, and it seemed before he knew it, he had collected more than 250 of them—some from plants that were never even completed. “When you look at the collection, you will see an interesting story of where nuclear power has been, and how far it has come,” he said.

Any method that can enhance safety, reduce risk, and lower costs is worth a second look. When that method proves it has the potential to optimize aging management at any nuclear power plant, it’s time to spread the word.

In 2019, a small team focused on selective leaching began looking for a way to use risk insights to optimize the implementation of deterministic aging management programs (AMPs). What they started soon grew into a large team effort by Constellation, Ameren, the Electric Power Research Institute (EPRI), and the Nuclear Energy Institute (NEI), along with contractors Enercon and Jensen Hughes, to develop a generic framework and then test it in two very different pilot applications.

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.
