In February 1957, construction was completed on the Sodium Reactor Experiment (SRE), a sodium-cooled, graphite-moderated reactor with an output of 20 MWt. The design of theSRE had begun three years earlier in 1954, and construction started in April 1955. On April 25, 1957, the reactor reached criticality, and the SRE operated until February 1964.

The documentary film Richland, which won awards at the Tribeca Festival and Sheffield (U.K.) DocFest last year, continues to gain exposure. Directed by Irene Lusztig, a self-described “feminist filmmaker, archival researcher, educator, and seamstress,” the documentary explores the community and “nuclear origin story” of Richland, Washington, a town that was built by the U.S. government to house Hanford Site workers who made the weapons-grade plutonium for the atomic bombs of the Manhattan Project.

Washington State University offered a free screening of the documentary last week at its main Pullman campus, followed by a discussion with the director and Robert Franklin, an assistant professor in history at the university’s Tri-Cities campus and the assistant director and archivist for the Hanford History Project.

Remembering ANS Past President Joseph Hendrie

January 11, 2024, 3:01PMNuclear News

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).

Reviewing the top nuclear headlines from 2023

January 7, 2024, 10:10AMNuclear News

The new year is here, and so it is time for the Nuclear News review of 2023's top stories. The recap will appear in the January issue of the magazine, on its way to American Nuclear Society members right now. In the meantime, all ANS members can read the year's issues in the ANS member center, and also review some of the most-read stories from Nuclear Newswire below. Here’s to a Happy New Year!

The Carolinas-Virginia Tube Reactor

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.

Eisenhower’s “Atoms for Peace” at 70

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.)

The design and legacy of Experimental Breeder Reactor-II

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.

A piece of nuclear history: Digitizing archived nuclear films

November 8, 2023, 3:00PMANS News

As far back as the 1940s, the U.S. Atomic Energy Commission and other organizations commissioned dozens of nuclear energy–related educational films. They delve into a variety of topics, including the development of nuclear reactors, radiation and reactors for space, and the political history of nuclear technology in the United States.

Bringing nuclear history forward

September 21, 2023, 7:02AMNuclear NewsJeremy Hampshire

This year’s American Nuclear Society Annual Meeting was filled with great content, some of which was covered in the August issue of Nuclear News (beginning on p. 22). One of the meeting’s executive sessions, “Bringing Nuclear History Forward,” focused on advanced reactor (AR) history and was well attended. The United States—along with many countries around the world—is turning to nuclear to combat climate change. Part of this is funding new and innovative companies to create first-of-a-kind nuclear reactors to provide abundant and clean power. Looking at the current designs of interest to the community brings up interesting comparisons to the test and experimental reactors of the past. Test reactors like the Experimental Breeder Reactor-II (EBR-II), the Fast Flux Test Facility (FFTF), Peach Bottom, Fort St. Vrain, Germany’s AVR, and others now are more important than ever in providing insight, data, and operational lessons learned to develop the next generation of reactors.

Big Bang fusion 13.8 billion years ago and its importance today

August 4, 2023, 3:00PMNuclear NewsM. W. Paris and M. B. Chadwick

In Big Bang nucleosynthesis (BBN), the deuterium-tritium (DT) fusion reaction 3H(d,n)4He, enhanced by the 3/2+ “Bretscher resonance,” is responsible for 99 percent of primordial helium-4. While this fact has been known for decades, it has not been widely appreciated. The importance of the resonant nature of the DT fusion reaction has been amplified by recent activities related to the production and use of terrestrial fusion, including the recent net-gain shot at the National Ignition Facility (NIF). Here, we aim to highlight the anthropic importance of the 4He-producing DT reaction that plays such a prominent role in models of nucleosynthetic processes occurring in the early universe. This primordial helium serves as a source for the subsequent creation of more than 25 percent of the carbon (12C) and other heavier elements that compose a substantial fraction of the human body. Further studies are required to determine a better characterization of the amount of 12C than this lower limit of 25 percent. Some scenarios of core stellar nucleosynthetic yield of 12C suggest that even higher percentages of carbon from primordial helium are possible.

Gas-cooled reactors and Fort St. Vrain

Gas-cooled reactors have roots that reach way back to the development of early experimental reactors in the United States and Europe. In the United States, early experimental reactors at Oak Ridge and Brookhaven National Laboratories were air-cooled, as were early production reactors known as the “Windscale Piles” in the United Kingdom. Dragon, also located in the United Kingdon and operational from 1965 to 1976, used helium as the coolant and graphite as the moderator.

Twenty years ago, utility execs tried to predict the future

July 6, 2023, 12:01PMNuclear News

In January 2003—early in the “nuclear renaissance” of the 2000s—around 70 nuclear utility executives attended an ANS Utility Executive Conference, which was organized around the theme “Future Vision.” They traveled to Scottsdale, Ariz., to discuss how the nuclear community could achieve the bright future they envisioned just ahead—does that sound familiar?
