Nuclear News

The Feinstein Institutes for Medical Research, home of the research institutes of New York’s Northwell Health, announced it has received a five-year, $2.9 million grant from the National Institutes of Health to investigate the potential of human ghrelin, a naturally occurring hormone, as a medical countermeasure against radiation-induced gastrointestinal syndrome (GI-ARS).

Six months into my ANS presidency, the pace has been hectic yet good. I’ve taken nearly two dozen trips to student and local chapters; companies; and various regional, national, and international meetings, where I’ve spoken about the current and future path of nuclear: people-centered interactions that focus on the benefits and capacities of our technologies.

Perception, timing, and financing remain challenges. Perception can be addressed in our deeds, so I am heartened by continuing industry collaborations and subsequent communication to strengthen efforts in the arenas of energy security, environmental stewardship, and (inter)national leadership as we assist new-to-nuclear nations; leverage our outreach, educational, and policy instruments; and volunteer our expertise.

In November, I joined ANS’s delegation to COP29 Baku, Azerbaijan, where we strove be the voice of the nuclear community. Our presence at this and future Conferences of the Parties is necessary if we are to continue the momentum around nuclear science and technology.

Williams

President Trump has selected Brandon Williams to head the Department of Energy’s National Nuclear Security Administration, pending confirmation by the U.S. Senate.

Williams is a former one-term congressman (R., N.Y.),from 2023 to the beginning of 2025. Prior to political office he served in the U.S. Navy. Williams’s run for office gained attention in 2022 when he defeated fellow navy veteran Francis Conole, a Democrat, but he lost the seat last November to Democrat John Mannion.

“I will be honored to lead the tremendous scientific and engineering talent at NNSA,” Williams said, thanking Trump, according to WSYR-TV in Syracuse, N.Y.

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 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.

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.

The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-­ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.

Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?

As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?
