In 1989, the Savannah River Plant was renamed the Savannah River Site. It was originally established in 1950 near Aiken, S.C., to produce nuclear materials for the nation, primarily for defense purposes. The site consisted of a heavy water production plant, three fuel fabrication facilities, five production reactors, two nuclear separation facilities, waste management facilities, tritium processing facilities, and the Savannah River National Laboratory. The main isotopes produced were, by priority, tritium, plutonium-238, and plutonium-239.

This month’s Nuclear News features our inaugural 40 Under 40 list of the brightest rising stars in the nuclear field.

The time has clearly come for this feature. The current resurgence of nuclear isn’t just a technological transformation; it’s also a changing of the guard. Consider this: For the first time in modern history, the American Nuclear Society has more members under the age of 40 than over the age of 60.

Of course, for as long as I can remember, the nuclear workforce has always been a bit of a double-humped demographic camel. Picture a nuclear workforce age chart and you will see two distinct peaks, or what a statistician might call a “bimodal distribution.” “Peak 1” is on the right and is centered over the Baby Boomer generation, many of whom entered the industry in its heyday of the 1960s and ’70s. These are the men and women who built the nuclear enterprise as we know it today.

Several questions loom after federal and state elections: What does the future hold for nuclear science and technology? Will there be a shift in direction? How do we continue and expand our impact on energy and nonenergy initiatives? The American Nuclear Society is an organization of people, policies, and products. We innovate, educate, and facilitate collaboration. We advance the field, serving our members and engaging with communities. With every travel assignment, I have witnessed the collective passion and action of our members toward fuller participation and societal enhancement based on nuclear technology. The work is not done, but there is forward momentum.

We have never been a field that does not answer the call, and at this year’s Winter Conference and Expo, we explored the very apt theme “Now comes the hard part.”

Among the plenaries and technical sessions were panels about engaging and educating the next generation of nuclear professionals, the growth of nuclear engineering departments in higher education, a student design competition, and—as one might expect in November during an election year—keeping nuclear out of the political fray.

Gail H. Marcus—ANS member since 1973

November 25, 2024, 7:03AMANS News

I like to say that I ended up at Massachusetts Institute of Technology because of my father. He saw that I seemed intimidated by the prospect of going there, so he dared me, figuring I would take the bait. And I did.

I graduated with a bachelor’s and master’s in physics in 1968, and two days later I married my classmate, Mike Marcus. After a summer at Ft. Monmouth, where I studied radiation damage to semiconductors, we spent the next few years back at MIT in grad school—Mike in electrical engineering and I in nuclear engineering. It was Mike who steered me toward nuclear engineering, noting that my interest was radiation damage to materials, and the nuclear engineering department was doing more of that than the physics department.

Nuclear waste: Trying again, with an approach that is flexible and vague

The Department of Energy has started over on the quest for a place to store used fuel. Its new goal, it says, is to foster a national conversation (although this might better be described as many local conversations) about a national problem that can only be solved at the local level with a “consent-based” approach. And while the department is touting the various milestones it has already reached on the way to an interim repository, the program is structured in a way that means its success will not be measurable for years.

N.S. Savannah: Bridging the gap between decommissioning and historic preservation

It’s safe to say that readers of Nuclear News are familiar with decommissioning. It’s even safe to assume that experienced decommissioning practitioners are familiar with the National Historic Preservation Act (NHPA) and how it applies to typical projects. What’s different about the N.S. Savannah is that the entire project site is a historic property—and in fact, is a federally owned National Historic Landmark (NHL), a status that confers the highest level of protection under law. Federal owners of NHLs are obligated to minimize harm in both planning and actions. Distilled to its salient point, no federal owner of an NHL should destroy it if there’s a reasonable alternative. That level of preservation is not what we normally associate with nuclear decommissioning. This perfectly summarizes the challenges, and opportunities, that decommissioning Savannah offered. The story of how the Maritime Administration (MARAD) managed these two otherwise contradictory processes showcases how historic preservation and decommissioning can positively intersect, provides a pathway for other historic facilities, and further adds to the already illustrious history of one of our nation’s significant 20th century landmarks.

Some 30 nuclear engineering departments at universities across the United States graduate more than 900 students every year. These young men and women are the present and future of the domestic nuclear industry as it seeks to develop and deploy advanced nuclear energy technologies, grow its footprint on the power grid, and penetrate new markets while continuing to run the existing fleet of reactors reliably and economically.

My Spaceship Earth: A structural engineer’s path to nuclear

While flipping through the course catalog at the University of Massachusetts–Amherst, I read that civil engineers can design amusement park rides. I was instantly inspired and chose my major because I wanted to design something for Walt Disney World. After college, I started my dream job at Simpson Gumpertz & Heger, which is famous for designing Spaceship Earth at Epcot Center, a celebration of human innovation, communication, and the progress of civilization. This was a win.

My introduction to nuclear

During my first two years at SGH, I experienced all aspects of working in the Engineering Mechanics & Infrastructure group, from analyzing structural failures to studying pipelines and modeling antennas. In 2006, I worked on my first nuclear facility. It consisted of structural analysis and design of the Integrated Waste Treatment Unit at Idaho National Laboratory.

Constellation Energy has announced that it will seek to restart Unit 1 of the Three Mile Island nuclear power plant in Pennsylvania as part of an agreement with Microsoft to power that company’s data centers. Given the growing interest by tech companies in using clean, reliable nuclear power to meet their growing energy demands, the September 20 announcement to reopen TMI-1, which was shut down and defueled in 2019, was not a huge surprise.

New meeting, better story

As you may have heard, the American Nuclear Society recently entered into a 50/50 joint venture with the Nuclear Energy Institute to host an annual industrywide meeting in late summer, which will replace ANS’s Utility Working Conference and NEI’s Nuclear Energy Assembly. Simply put, we are taking the best of both events to create the ultimate nuclear power meeting of the year. If you are a longtime UWC attendee, you will feel right at home in the aisles of the exhibit hall, or in the working sessions designed to tackle the shared practical challenges operators face. NEI will bring the nuclear C-suite presence along with the freshest insights on industrywide issues.

The U.S. nuclear industry is growing, and we need to get even bigger if we are going to make good on the promise of a resurgence. The auto industry has SEMA, the tech industry has CES. It’s time the U.S. nuclear industry had its top event of the year.

Fatigue has been identified as a major risk factor in industrial accidents. According to the National Safety Council, 13 percent of workplace injuries can be attributed to fatigue.1 Other research indicates that working 12 hours per day is associated with a staggering 37 percent increase in risk of injury.2 Considering fatigue was a contributing factor to major nuclear accidents at Chernobyl and Three Mile Island, it makes sense that the Nuclear Regulatory Commission imposes hefty fines to ensure strict adherence to its fatigue management regulations—particularly, Code of Federal Regulations Title 10, Part 26, “Fitness for Duty Programs.”

Live long and prosper

October 11, 2024, marked the 70th anniversary of the American Nuclear Society. Taking a long view, we have not looked back and instead have tackled challenges and moved forward with lessons learned. Whether we pull examples from energy or nonenergy aspects of our nuclear enterprise, our planet has benefited from nuclear science and technology, and ANS has been there every step of the way.

As the Society reflects on its own history, let us remember:

  • The first commercial nuclear power stations started operation in the 1950s.
  • Nuclear energy now provides about 9 percent of the world’s electricity from about 440 power reactors.
  • Nuclear provides about 25 percent of the world’s low-carbon electricity.
  • Nuclear is the world’s second-largest source of low-carbon power.
  • More than 50 countries utilize nuclear energy in about 220 research reactors. In addition to research, these reactors are used for training and for the production of medical and industrial isotopes.

The U.S. Navy’s Surface Ship Support Barge, converted in the 1960s from a WWII T2 tanker to a support barge to accept spent nuclear fuel during the refueling of nuclear aircraft carriers, was dismantled and disposed of by the nuclear decommissioning company APTIM as a first-of-its-kind vessel dismantlement project for the Navy. The project was executed under contract with Naval Sea Systems Command; however, regulatory oversight was accomplished through an interagency framework agreement between the U.S. Navy and the Nuclear Regulatory Commission.

Commercial nuclear power is illegal in Australia, and it has been since the 1990s. This past June, however, the country’s main opposition party announced plans to build seven commercial nuclear reactors in the 2030s and 2040s on sites presently occupied by aging coal-fired plants—should the party’s Liberal–National Coalition win power in federal elections next year. This statement has reignited a public debate regarding the potential role of nuclear energy in Australia.

Unit 2 at the Prairie Island nuclear power plant near Red Wing, Minn., underwent an outage in fall 2023, which included extensive work on the reactor vessel using a novel approach to replace baffle-former bolts and lower radial clevis insert bolts. The work relied on extensive analysis beforehand to determine which bolts to replace such that only the new bolts were structurally credited for performance of their safety function. This proactive approach eliminated the need for costly contingencies associated with inspections.
