According to the Council on Radionuclides and Radiopharmaceuticals, more than 82,000 nuclear imaging procedures using nuclear medicine are performed throughout the world every day. To administer these vital medical procedures, radiopharmaceutical companies and hospitals rely on a handful of producers of medical radioisotopes.

The adage “a rising tide raises all boats” keeps coming to my mind whenever I think about the work ahead for small modular reactor and advanced reactor development companies. The groundwork being laid by the entire industry is key to moving the whole group forward together. The drive to construct new nuclear will need to include all sizes, designs, and companies, because unlike in many industries, there is no way there can only be one “winner” if we are to meet climate goals.

Recently, at global climate summit COP28, a large portion of the international community announced a joint aim to triple worldwide nuclear power generation by 2050. This is tremendous news and a huge step in the right direction for many reactor developers. It means that the work developers are doing now will lead to a market for their product for years to come. The questions we must all be asking are “How do we get there?” “Who is going to take the leap of faith to build the first-of-a-kind designs?” and “What challenges lie ahead?”

Designs for high-tech products, and the start-ups that offer them, will always outnumber the commercial successes. Ditto: many more power plants are proposed than actually get built, no matter what the technology.

This is an axiom of free-market economies, but in early November 2023 it became painfully obvious in the advanced reactor field. NuScale Power, the only advanced reactor that has made it through the licensing gauntlet, acknowledged that the consortium of utilities that was its intended launch customer had failed to put together a feasible package.

Are you an energy genius? It’s hard to tell whether or not Americans are really aware of the energy that controls our lives, so the following quiz should be revealing. Click through the multiple-choice options below to reveal the answers. Most answers can be found in the pages of the 2023 issues of Nuclear News—if you’ve been a diligent NN reader you should do fine!

Scoring: Zero to five correct answers out of the 20 questions means you may need to read up on energy in order not to be at the mercy of others. Six to 10 correct answers is a good passing grade. Eleven to 15 right answers means you’re really energy literate. Sixteen to 19 correct answers means you should be advising Congress. Twenty right answers suggests you’re Mr. Spock reincarnated.

This article is the first in a series that will examine the history of small modular reactors.

Small and medium reactors have been an integral part of the U.S. nuclear power enterprise since the early days of the industry. Many of the designs for the next generation of reactors are rooted in the designs of the 1950s and ’60s, but the development and push for deployment have gained momentum only within the last decade.

This recent momentum led a reader of Nuclear News to suggest an article reviewing the history of small modular reactors. NN staff jumped on this idea, deciding a series of articles would do better justice to such a complex and interesting topic.

Joseph Hendrie, Brookhaven National Laboratory physicist, NRC chair, and ANS past president (1984–1985), passed away in his home in Bellport, N.Y., on December 26 at the age of 98.

Hendrie, an American Nuclear Society member since 1956, was a leader in the nuclear community for much of his 45 years in nuclear reactor safety research. He served as the deputy director for technical review of the Atomic Energy Commission’s Directorate of Licensing from 1972 to 1974 and then was appointed chair of the NRC in 1977 (serving a second stint as chair in 1981—the only person to serve two nonconsecutive terms in that role).

Another calendar year has passed. Before heading too far into 2024, let’s look back at what happened in 2023 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 January through March 2023.

Stay tuned for the top stories from the rest of the past year.

The Carolinas-Virginia Tube Reactor (CVTR), also known as Parr due to its location in Parr, S.C., was a 65-MWt (17-MWe) pressurized tube reactor. Construction began in January 1960, and the reactor reached initial criticality in March 1963. Commercial operation commenced in December 1963, and the reactor was permanently shut down in January 1967 after the test program was complete.

The World Nuclear Association and the African Commission on Nuclear Energy (AFCONE) last year signed a memorandum of understanding to encourage the use of nuclear energy in support of economic growth and sustainable energy development in Africa.

“The tools of the academic designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone sees it.”

Many in the nuclear community are familiar with this sentiment from Admiral Rickover. A generation of stagnation in the industry has underscored the truth of his words. But as economies around the world put a price on carbon emissions, there’s a renewed sense of urgency to deploy clean energy technologies. This shifts the global balance of economic competitiveness, and it’s clear that the best path forward for nuclear requires combining the agility of private innovators with the technology and capabilities of national laboratories.

Carson Noack is a busy young man with a clear vision of the future of energy. The 23-year-old undergraduate is slated to receive his bachelor’s degree in mechanical engineering from Abilene Christian University (ACU) in 2024. He’s also a researcher in the university’s Nuclear Energy eXperimental Testing (NEXT) Laboratory, which has been making news with its plans to build the first new research reactor in the United States in more than 30 years—the Molten Salt Research Reactor (MSRR).

Seventy years ago to the day, President Dwight D. Eisenhower gave his historic address to the United Nations General Assembly in New York City. (See December 2023 Nuclear News's “Leaders” column to read the reflections of Kathryn Huff, the Department of Energy’s assistant secretary for nuclear energy, on the speech’s anniversary.)

This spring, Waste Management Symposia will celebrate its 50th anniversary when the conference convenes in Phoenix, Ariz., on March 10–14, 2024. Since the first international conference in 1974, WMS has grown to nearly 3,000 attendees representing more than 30 countries. The conference is an open forum for the exchange of information and discussion of opportunities related to all aspects of radioactive waste and materials management. As a nonprofit organization, all proceeds from the WMS conference go toward providing education and information on global radioactive waste management.

If you head west out of Idaho Falls on U.S. Highway 20 and make your way across the Snake River Plain, it won’t be long before you’ll notice a silver dome in the distance to the north. One of the most recognizable structures in the history of nuclear energy, Experimental Breeder Reactor-II stands out from the desert landscape. The 890-square-mile site on which EBR-II is located is the former National Reactor Testing Station, now known as Idaho National Laboratory.

The Philippines generates none of its electricity from nuclear energy. Until recently, it was even without a functioning research and training reactor. The lack of a nuclear facility has led to a dearth of scientific expertise in nuclear science and nuclear engineering in this nation of roughly 117 million people. Twenty-nine-year-old Ronald Daryll E. Gatchalian is on a mission to change that.

The Department of Energy’s Office of Environmental Management is responsible for roughly 90 million gallons of radioactive liquid waste at Idaho National Laboratory, the Hanford Site in Washington state, and the Savannah River Site in South Carolina. About 900,000 gallons of waste are stored at INL, 56 million gallons at Hanford, and roughly 36 million at SRS. A further 400,000 gallons of waste from various operations are being stored at the Oak Ridge Site in Tennessee.

Over the past 50 years, the use of nuclear energy has avoided approximately 70 gigatons of carbon dioxide emissions globally and 24 gigatons in the United States.¹ Although carbon dioxide is not being released into the atmosphere when generating energy from nuclear, the waste this energy form does produce must be managed and permanently isolated away from people and the environment.
