Nuclear History

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.

The July 2024 issue of Nuclear News focused on fusion. Editor-in-chief Rick Michal highlighted in his column (p. 4) Los Alamos National Laboratory’s open access special issue of the American Nuclear Society journal Fusion Science and Technology, titled The Early History of Fusion. This article provides a brief summary of the issue—and we encourage readers to explore all of the full papers.^a

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.

A trailblazing nuclear trade journalist, a UFO-debunking nuclear physicist–turned–space scientist, and the engineer behind both America’s first licensed reactor and the world’s first nuclear-powered merchant ship: this was the visionary trio who founded the American Nuclear Society 70 years ago.

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.

Julie and Jim Byrne on their wedding day, May 22, 1976.

As I was finishing my studies at the University of Pittsburgh and about to graduate with a degree in civil engineering, I talked to a local navy recruiter about a position with the Seabees. He told me there were no Seabee billets, but that the navy had a nuclear power program that might interest me. When I said yes, it wasn’t long before I was whisked off to Washington, D.C., to interview with someone named Admiral Hyman Rickover. The one thing they told me was to stand up to “the kindly old gentleman.”

The day started with technical interviews and then I was ushered into the admiral’s office. I was a typical college student, and I spent my money on food and beer and not on haircuts. On seeing me, Admiral Rickover told me that I looked like a girl. After a bit of back-and-forth, he asked me a couple of other questions. His last comment to me was that I must know something and to get out of his office.

Fulton Station was to be a two-unit high-temperature gas-cooled reactor that was originally planned to start commercial operation in 1981 for Unit 1 and in 1983 for Unit 2. Each reactor was to provide 1,160 MWe of power. The nuclear steam supply system (NSSS) and fuel were to be developed by General Atomics (GA), and engineering firm Stone & Webster was charged with handling the construction. The Philadelphia Electric Company (PECO) had big plans for Fulton Station, but ultimately, the plant was never built.

This year marks the 70th anniversary of the founding of the American Nuclear Society.

Plenty of sources incorrectly list our birthday, but the reality is that October 11, 1954, is the correct date for the establishment of ANS.

John Kelly, ANS past president (2018–19), passed away peacefully in his sleep on October 3, 2024, in Gilbert Ariz., at the age of 70. Kelly was born on March 9, 1954, and was the eldest of Jack and Aileen Kelly’s six children.

His career, which spanned more than 40 years, began at Sandia National Laboratories in Albuquerque, N.M., where he focused on safety and severe accident analysis. His leadership led him to Washington D.C., where he served as the deputy assistant secretary for nuclear reactor technologies at the U.S. Department of Energy. Kelly played a critical role in shaping nuclear policy and guiding the world through significant events, including the Fukushima Daiichi accident in Japan. At the end of his career, he was honored to serve as the American Nuclear Society’s president. In retirement, he was actively involved with ANS in technology events and mentoring the next generation of scientists.

Kelly is survived by his wife, Suzanne; his children Julie Kelly-Smith (Byron), John A. (Sarah), and Michael (Nicole); and grandchildren Kiri and Kyson Smith and John and Maximilian Kelly. His family was his pride and joy, including his cherished dog, Covie, who brought him happiness in recent years.

In lieu of flowers, donations may be made to the American Nuclear Society or Detroit Catholic Central High School (27225 Wixom Road, Novi, MI 48374). Please designate Memorial and specify John Kelly ’72 Memorial Fund.

In honor of Kelly's commitment to ANS and to celebrate his life, his profile from the July 2018 issue of Nuclear News is published below.

The American Nuclear Society was formed in 1954 in the wake of President Eisenhower’s seminal Atoms for Peace speech. Around the same time that Congress was debating the Atomic Energy Act and John Landis was helping establish ANS, the National Security Council began deliberating about adding a nuclear-­powered merchant ship to the nascent Atoms for Peace program. We like to imagine that the idea germinated after Mamie Eisenhower christened the U.S.S. Nautilus, but the truth seems much drier. Regardless, Ike championed the project and announced it to a surprised crowd in an April 1955 speech in New York City at the Waldorf Astoria Hotel. Landis would become the principal architect of the ship’s nuclear power plant. Although Savannah’s reactor now rests in the low-level radwaste repository in Clive, Utah, the ship’s prospects are as bright as the future of ANS itself.

Ian Wall early in his career . . .

I graduated with a degree in mechanical engineering from Imperial College, London, in 1958. Nuclear power was viewed favorably at the time, so I took a 1-year course on the subject. I was then offered fellowships at Cambridge University and the Massachusetts Institute of Technology and thought the latter would be more interesting, so I moved to Cambridge, Mass., to study nuclear engineering. After completing my doctorate in 1964, I joined the American Nuclear Society and took a job with General Electric, then in San Jose, Calif.

In 1967, GE assigned me to explore the use of probability in reactor safety. At that time, the prevailing opinion was that the probability of a severe accident was infinitesimally small and the consequences would be catastrophic.

The Hallam nuclear power plant in Nebraska, about 25 miles southwest of Lincoln, was a 75-MWe sodium-­cooled, graphite-moderated reactor operated by Consumers Public Power District of Nebraska (CPPD). It was co-located with the Sheldon Power Station, a conventional coal-fired plant. The facility had a shared control room and featured a shared turbo generator that could accept steam from either heat source.

Tonight, Democratic presidential candidate Kamala Harris is expected to offer some policy details in a speech at the Democratic National Convention. With nuclear energy getting firm bipartisan support in Washington, D.C., it won’t come as a surprise if Harris backs nuclear power investments as part of her energy and climate policies.

But 11 campaigns and 44 years ago, in 1980, President Jimmy Carter and Republican presidential candidate Ronald Reagan were on the campaign trail in the first presidential election contest after the March 1979 accident at Three Mile Island. Democratic and Republican party operatives hashed out policy platforms that took stock of nuclear energy—and Nuclear News took note.

Crews are making significant progress on the construction of the K-25 viewing platform at the Oak Ridge Reservation in Tennessee, the Department of Energy’s Office of Environmental Management announced on August 20. When completed next year, the elevated platform will offer a sweeping panoramic view of the massive 44-acre footprint of the K-25 Building, which once produced enriched uranium used in the weaponry that ended World War II.

The first high-temperature, gas-cooled reactor ever built in the United States was Unit 1 at the Peach Bottom Atomic Power Station. This demonstration plant, located on the Susquehanna River approximately 80 miles southwest of Philadelphia, Pa., was tasked with validating HTGR design codes. It produced over 1.2 million megawatt-hours of electricity over 1,349 equivalent full-power days (EFPDs), which was distributed by the Philadelphia Electric Company.

August 10, 2024, marks the 106th birthday of Vice Admiral Eugene P. “Dennis” Wilkinson of the U.S. Navy (who died in his 95th year in July 2013). It is a fitting time to reflect on and honor the man who contributed so much to the navy and the worldwide nuclear power industry.

This video about the Battle of Leyte Gulf in October 1944—the largest naval battle of World War II and a major contributing factor to the end of Japanese involvement—provides an exciting recount of the heroic U.S. submarines USS Darter (SS-227) and USS Dace (SS-247). A young Dennis Wilkinson was the torpedo data computer operator on the Darter, for which he was awarded the Silver Star. Wilkinson’s first-person recollections of this pivotal moment in U.S. naval history have been collected in Underway on Nuclear Power: The Man Behind the Words (2016, ANS).

The United States and Japan began rebuilding relations after the war. In 1966, Wilkinson, by then an admiral, was assigned chief of staff, U.S. Forces Japan, to continue those efforts.

Fast burst reactors were the first fast-spectrum research reactors to reach criticality by using only prompt neutrons with high-enriched uranium as fuel, creating a pulse for microseconds. Among many achievements, fast burst reactors were the first research reactors to demonstrate the ability of thermal expansion to terminate a pulse and to show how this could aid in reactor safety. In addition, fast burst reactors were pivotal in early fission studies including critical mass determination, criticality safety, the study of prompt and delayed neutrons, and much more.

In May’s Nuclear News (p. 86), we reviewed Argonne National Laboratory’s comprehensive work on fast reactors in Idaho. In this article, we summarize the light water reactor work there.¹

In the early days, there were few data on the behavior of reactor materials under severe neutron bombardment. In collaboration, Oak Ridge National Laboratory and Argonne National Laboratory developed the Materials Testing Reactor (MTR) for the National Reactor Testing Station (NRTS) in Idaho. The materials tested in it over the course of 15,000 experiments were reactor fuel materials, structures, cooling systems, and shields. It operated from 1952 to 1970.

Idaho’s nuclear energy history is deep and rich. The National Reactor Testing Station (NRTS) began its history as an artillery testing range in the 1940s.¹ Following World War II, Walter Zinn, Argonne National Laboratory’s founding director and Manhattan Project Chicago Pile-1 project manager, proposed to the Atomic Energy Commission that a remote location be found for building test reactors. In 1949, he and Roger S. Warner, AEC’s director of engineering,² developed a list of potential sites from which the NRTS was selected. Over the decades, quite a few companies and AEC national laboratories built 52 experimental and test reactors at the NRTS, including 14 by Argonne.³ (For a brief AEC video on the NRTS, see youtube.com/watch?v=C458NsH08TI.)

When the U.S. Fusion Energy Outreach Team declared the second week of May as Fusion Energy Week, they were recognizing the May 10 birthday of Cecilia Payne-Gaposchkin—the British-born American astronomer who applied principles of quantum physics, chemistry, and astronomy to become the first to realize—at the age of 25—that stars and the universe itself are mostly composed of hydrogen and helium, and that the stars could be sorted by their spectra into groups that corresponded to the temperature of the stars.
