Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory are using a stellarator they designed and built using permanent rare-earth magnets and a 3D-printed shell to help test new fusion power concepts. MUSE—the first stellarator built at PPPL in 50 years—took one year to construct and generated its first plasma in February 2023. The work that went into its design has already inspired a stellarator power plant concept being developed by a commercial spin-off, Thea Energy.

Next-generation reactor company Oklo Inc. is teaming up with Diamondback Energy Inc. to bring Oklo’s Aurora Powerhouse units to the American Southwest.

The companies signed a nonbinding letter of intent (LOI) this week to collaborate on a 20-year power purchase agreement that would provide 50 MW of electricity per unit to Diamondback’s Permian Basin operations area. The agreement lays out options to renew and extend the agreement for an additional 20-year term, since the units are designed to operate for 40 years without needing to refuel. Diamondback is an independent oil and gas company headquartered in Texas.

Unit 2 of South Korea’s Shin-Hanul nuclear power plant entered commercial operation on April 5, Korea Hydro & Nuclear Power announced. It is the nation’s 26th operating reactor, which continues the upward nuclear trend as South Korea reverses a previous phase-out plan for nuclear.

Energy secretary Jennifer Granholm submitted a Department of Energy report to the U.S. Congress on April 8 detailing the state of research reactors at U.S. universities and the potential need to upgrade or build additional reactors, including advanced nuclear reactors and test facilities.

Systems for Nuclear Auxiliary Power (SNAP) was an Atomic Energy Commission program with the goal of producing a portable and dependable power source centered around nuclear technology that could be utilized in land, sea, and space applications. The program aimed to provide a compact reactor—a necessity for space applications—and ran from 1955 until 1973, when it was discontinued.

To help expand access to clean nuclear energy, the Department of Energy announced it has awarded more than $19.1 million to support nuclear energy research and development, university nuclear infrastructure, and undergraduate and graduate education.

U.S.-based reactor company X-energy has partnered with Canadian power producer TransAlta Corp. to study the feasibility of deploying an advanced small modular reactor at a fossil fuel power plant site in Alberta.

Once used for applications in medicine, industry, and research, many countries now have legacy radium-226 sources, according to the International Atomic Energy Agency. With the support of the IAEA’s technical cooperation program, these disused sealed radioactive sources are being recovered, and countries are improving national capacities for their long-term management, including their potential reuse and recycling.

A new study by the Government Accountability Office researched potential impacts of climate change–related hazards on the U.S. nuclear fleet and found clear risks. In the report, which was released to the public last week, the GAO recommends that the Nuclear Regulatory Commission address these possible threats during the licensing process.

Charles L. Harper understands disadvantage. It was his personal drive and love for learning that pushed him to leave inner-city Detroit, join the U.S. Navy, earn degrees in psychology from Wayne State University and the University of Detroit, and enjoy a successful career as a clinical psychologist. He served as a strong role model for his son Jeffrey, who is an entrepreneur and international energy executive.

The Harper men have many things in common. According to Jeffrey, “Both my dad and I share a common self-motivation and a love for learning, but the most critical thing we share is the continual quest for opportunity, which led us both to moments of predestination that changed our lives.” And now, in honor of his father, the younger Harper has used these qualities to found Charles Harper Charities (CHC) with the aim of introducing disadvantaged youth to the world of nuclear engineering.

One CHC offering helps rising high school seniors attend a summer program to prepare them for college and introduce them to nuclear engineering. This summer’s Nuclear Engineering Opportunity Program, which will be CHC’s inaugural course, will be held at the University of Michigan in conjunction with the Department of Nuclear Engineering and Radiological Sciences (NERS) and the College of Engineering’s Office of Culture, Community, and Equity. The monthlong residential course will host rising seniors from Detroit at no cost to them and will introduce them to STEM subjects and provide tours of nearby nuclear facilities.

Ukraine’s Zaporizhzhia nuclear power plant lost the connection to its only remaining backup power line last Thursday amid renewed indications of military activity in the area, the International Atomic Energy Agency reported.

Beshear

Kentucky Gov. Andy Beshear vetoed legislation last week that would have supported a push to bring nuclear energy to the Bluegrass State.

The governor said his objection to Senate Bill 198 is due to how voting members for the Kentucky Nuclear Energy Development Authority would be selected—and that it is not a reflection on his views toward nuclear power. The bill as written would designate members of the board from the private sector, bypassing the appointment authority of the governor or other state constitutional officers.

“The legislature can’t just say, ’You in this position in the private sector and you in that position on a private sector association are automatically on a board,’ and then [be] given governing authority,” Beshear said at a news conference. “That’s not the way the executive branch works, not the way that the power can be delegated to carry out the law.”

As the world shifts toward clean and sustainable energy, Kazakhstan stands on the cusp of a significant move into nuclear energy. Kazakh president Kassym-Jomart Tokayev has suggested a national referendum to gauge the country’s position on building a nuclear power plant, setting the stage for an in-depth discussion about the nation’s energy trajectory.

X-energy UK Holdings and Cavendish Nuclear together received a government award of £3.34 million ($4.23 million) for further development of advanced modular reactors. The award, which was announced earlier this week, is from the U.K. government’s Future Nuclear Enabling Fund.

PSEG Nuclear LLC announced this week it will pursue subsequent license extensions to keep the three reactors at its Hope Creek and Salem plants operating for an additional 20 years. Both plants had been granted initial life extensions years ago by the Nuclear Regulatory Commission, Salem-1 and -2 on June 30, 2011, and Hope Creek on July 20, 2011.

The U.S. Nuclear Regulatory Commission’s Regulatory Information Conference—“the RIC” as it’s commonly known—is an annual rite of spring for many nuclear energy professionals. Each year, 2,000 industry people crowd into the Montgomery County Conference Center to hear the commissioners give their annual plenary speeches, attend technical sessions on regulatory topics, and kibitz with friends in the expansive foyer during breaks.

And as always, there are two distinct conversations at the RIC: the one that emanates from the stage, and the other that unfurls organically in the hallways. The official conversation is in the public record for anyone to read or watch. The hallway topic du jour this year was Part 53 of Title 10 of the Code of Federal Regulations, of course—specifically, the Staff Requirements Memo (SRM) handed down by the commission the week before that instructed staff to produce a new proposed rule for public comment and set a six-month countdown clock to finish it.

Jupiter

Clyde Peter Jupiter passed away peacefully March 31, 2024, at the age of 95. Born October 31, 1928, in New Orleans, La., Jupiter attended public and parochial schools in New Orleans, graduating from Xavier University in 1948. He was a member of the Alpha Phi Alpha fraternity and was noted as one of the first African Americans to attend Notre Dame University in 1949.

Following graduation, Jupiter pursued a career in the field of physics, where he was renowned for his contributions to nuclear radiation detection and the advancing of nuclear energy. His career in the nuclear field included working for such agencies as the Atomic Energy Commission, Lawrence Laboratories, and the Nuclear Regulatory Commission.

He also served in the U.S. Army from 1954 to 1956 at the Chemical Corps Laboratory, in Fort Detrick, Md.

Christensen

John Christensen, president and chief executive officer of Utilities Service Alliance (USA), has announced his retirement effective at the end of 2024. His career spans more than 41 years in the nuclear industry.

“The last 17 years have been some of the most challenging and gratifying years in my career,” he said. “The people I’ve had the opportunity to work with have been a great inspiration. I am extremely proud of everything we have accomplished since I joined USA.”

Ken Peters, USA’s chair of the board, noted, “John’s service and drive in helping the members of USA improve safety, plant operations and financial performance is a testament to his commitment to our industry. We wish John the very best in his retirement.”

Nuclear has been on a good roll lately and it is getting better. The 2022 Inflation Reduction Act (IRA) provides a nuclear power production tax credit. This has stopped the early retirement of deregulated units. The IRA also provides a benefit for the clean production of hydrogen. Many utilities have committed to a net-zero goal by 2050. Duke and other utilities have plans to transition coal plants to nuclear with small modular reactors.

And now, nuclear has a new supporter—tech companies.

The big U.S. utility companies (like Exelon, Duke, Dominion, Southern, and Entergy) are all projecting growth in electricity demand—primarily in the commercial sector but some residential growth is also expected. Commercial growth is being driven by new factories (thank you, IRA and CHIPS, that is, the Creating Helpful Incentives to Produce Semiconductors and Science Act). It is also being driven by data centers.
