Southern Nuclear was first when no one wanted to be.

The nuclear subsidiary of the century-old utility Southern Company, based in Atlanta, Ga., joined a pack of nuclear companies in the early 2000s—during what was then dubbed a “nuclear renaissance”—bullish on plans for new large nuclear facilities and adding thousands of new carbon-free megawatts to the grid.

In 2008, Southern Nuclear applied for a combined construction and operating license (COL), positioning the company to receive the first such license from the U.S. Nuclear Regulatory Commission in 2012. Also in 2008, Southern became the first U.S. company to sign an engineering, procurement, and construction contract for a Generation III+ reactor. Southern chose Westinghouse’s AP1000 pressurized water reactor, which was certified by the NRC in December 2011.

Fast forward a dozen years—which saw dozens of setbacks and hundreds of successes—and Southern Nuclear and its stakeholders celebrated the completion of Vogtle Units 3 and 4: the first new commercial nuclear power construction project completed in the U.S. in more than 30 years.

The Department of Energy’s Office of Environmental Management announced on January 16 that it has awarded a noncompetitive financial assistance agreement worth $37.5 million to Vanderbilt University in Nashville, Tenn., to aid the department’s mission of cleaning up legacy nuclear waste.

The Swedish Nuclear Fuel and Waste Management Company (Svensk Kärnbränslehantering AB, or SKB) broke ground on its spent nuclear fuel repository near the Forsmark nuclear power plant on January 15. SKB, which is owned by Sweden’s nuclear power plants, expects the final repository will be ready for disposal in the 2030s, and will be fully extended in the 2080s.

The International Energy Agency published a new report this month outlining how continued innovation, government support, and new business models can unleash nuclear power expansion worldwide.

The Path to a New Era for Nuclear Energy report “reviews the status of nuclear energy around the world and explores risks related to policies, construction, and financing.”

In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

Plastic waste pollutes oceans, streams, and bloodstreams. Nations in Asia and the Pacific are working with the International Atomic Energy Agency through the Nuclear Technology for Controlling Plastic Pollution (NUTEC Plastics) initiative to tackle the problem. Launched in 2020, NUTEC Plastics is focused on using nuclear technology to both track the flow of microplastics and improve upstream plastic recycling before discarded plastic can enter the ecosystem. Irradiation could target hard-to-recycle plastics and the development of bio-based plastics, offering sustainable alternatives to conventional plastic products and building a “circular economy” for plastics, according to the IAEA.

Progress continues for TerraPower’s Natrium plant, with the latest win coming in the form of a state permit for construction of nonnuclear portions of the advanced reactor.

Oak Ridge National Laboratory has for the first time designed, printed, and irradiated a specimen capsule—or rabbit capsule—for use in its High Flux Isotope Reactor (HFIR), the Department of Energy announced on January 15.

Wright

Chris Wright, president-elect Trump’s pick to lead the U.S. Department of Energy, spent hours today fielding questions from members of the U.S. Senate’s committee on Energy and Natural Resources.

During the hearing, Wright—who’s spent most of his career in fossil fuels—made comments in support of nuclear energy and efforts to expand domestic generation in the near future. Asked what actions he would take as energy secretary to improve the development and deployment of SMRs, Wright said: “It’s a big challenge, and I’m new to government, so I can’t list off the five levers I can pull. But (I’ve been in discussions) about how to make it easier to research, to invest, to build things. The DOE has land at some of its facilities that can be helpful in this regard.”

As demand for artificial intelligence and data centers grows, President Biden issued an executive order yesterday aimed to ensure clean-energy power supply for the technology.

Westinghouse Electric Company announced last week that NASA and the Department of Energy have awarded the company a contract to continue developing a lunar microreactor concept for the Fission Surface Power (FSP) project.

Tim Tinsley

I’ve been reflecting on the recent American Nuclear Society Winter Conference and Expo, where I enjoyed the discussion on recycling used nuclear fuel to recover valuable minerals or products for future applications. I have spent more than 30 years focusing on dissolving and separating nuclear material, so it was refreshing to hear the case for new applications being made. However, I feel that these discussions could go further still.

Radiation is energy, something that our society seems to have an endless need for. A nuclear power station produces a lot of radiation that is mostly discarded. But once fuel has been used, it still produces significant levels of radiation and heat energy. The associated storage, processing, and eventual disposal of this used fuel requires careful management and investment to protect systems and people from the radiation. Should we really disregard—and discard—this energy source, along with all the valuable minerals in the used fuel, when we could instead use it to deliver significant value to society?

The U.S. departments of Energy and State have signed a memorandum of understanding with the Republic of Korea’s ministries of Trade, Industry and Energy and of Foreign Affairs for the two nations to partner on nuclear exports and cooperation.

A newly published standard is now available at the ANS store.

The standard, ANSI/ANS-8.26-2024, Nuclear Criticality Safety Engineer Training and Qualification Program (revision of ANS-8.26-2007; R2022), presents the fundamental elements of a training and qualification program for individuals with responsibilities for performing the various technical aspects of criticality safety engineering.

Poneman

The Harvard Gazette recently featured an interview with Daniel Poneman, former president and chief executive officer of Centrus Energy and former deputy secretary of energy. In the interview, Poneman offered his views on the “comeback” of nuclear power, artificial intelligence, safety and security issues, advanced reactors, climate change goals, and other issues of interest to the nuclear energy industry.

Climate, demand, hyperscalers: In the article, Poneman explained the nuclear comeback in terms of the converging concerns about climate change and electricity demand, as well as the issue of “hyperscalers.”

Energy is a business, as well as a science and engineering discipline. Located in oil- and gas-rich Oklahoma, the University of Tulsa is well known for its McDougall School of Petroleum Engineering, but it does not currently offer degrees in nuclear engineering. However, it has been increasing its coverage of nuclear energy and sustainable energy through its energy-related curricula, including in its unique Master of Energy Business (MEB) program within the Collins College of Business—one of nine such programs offered in the United States.

The Department of Energy has announced a competitive funding opportunity of up to $13 million to help first movers defray the licensing costs of bringing advanced nuclear reactors to market.

Nuclear energy produces about 9 percent of the world’s electricity and 19 percent of the electricity in the United States, which has 94 operating commercial nuclear reactors with a capacity of just under 97 gigawatts-electric. Each reactor replaces a portion of its nuclear fuel every 18 to 24 months. Once removed from the reactor, this spent (or used) nuclear fuel (SNF or UNF) is stored in a spent fuel pool (SFP) for a few years then transferred to dry storage.

Another calendar year has passed. Before heading too far into 2025, let’s look back at what happened in 2024 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from October through December 2024.

Advanced nuclear reactor company Last Energy joined with two Republican state attorneys general in a lawsuit against the Nuclear Regulatory Commission, arguing that some microreactors should not require the commission’s approval.
