Systems for Nuclear Auxiliary Power (SNAP) was an Atomic Energy Commission program with the goal of producing a portable and dependable power source centered around nuclear technology that could be utilized in land, sea, and space applications. The program aimed to provide a compact reactor—a necessity for space applications—and ran from 1955 until 1973, when it was discontinued.

We welcome ANS members who have careered in the community to submit their own Nuclear Legacy stories, so that the personal history of nuclear power can be captured. For information on submitting your stories, contact nucnews@ans.org.

The James Wm. Behrens family legacy in America starts with Henry H. Behrens, who came across the pond from Germany in 1857. He was later joined by Wilhelmina, also from Germany, and they were married in Alton, Ill., in about 1862. One of their sons, George Wm. Sr., was my grandfather. He and his wife, Frances Walker (of Irish and English descent), had three sons, one of whom (George Wm. Jr.) was my father. I was born in 1947 and raised in the small country town of Bunker Hill, Ill. I attended Bunker Hill elementary and high schools, graduating from the latter in 1965.

Nuclear moments

Grace Stanke

I just spent 13 months as Miss America 2023 advocating for nuclear energy. Throughout those 13 months, I traveled approximately 280,000 miles to 23 states and eight countries. I have now seen eight different power plants (seven in the United States and one in Japan). I visited radiological isotope production facilities, reprocessing facility construction sites, research facilities, and more. My work extended to visits at schools, trips to talk with state and national legislators, and stops at varying professional groups looking to learn more about nuclear science. It certainly was an interesting year, and one that I could not have foreseen.

Experiences: One thing that this year has made me appreciate about the nuclear industry: No matter what facility, and no matter what country you are in, there is always a plan. I never thought I would be so giddy to walk into a power plant and sit down for a pre-job brief, but honestly, I love them now. The desire to be prepared and have a plan is not so present in most other industries!

Clementine—The world’s first fast neutron reactor

In March 1949—75 years ago this month—the 25-kilowatt reactor known as Clementine reached full power. As an experimental reactor, it had a rather long and successful run. It was the world’s first fast neutron (high-energy) reactor and operated from initial criticality in 1946 to final shutdown in 1952.

The Sodium Reactor Experiment

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.

What will happen to the retired nuclear-powered merchant ship, the N.S. Savannah? The Maritime Administration (MARAD) of the Department of Transportation is investigating possibilities for the vessel’s future, whether it be in disposition, transportation, or preservation.

Richland critiques “home, safety, [and] whiteness” of proud nuclear company town

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).

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.

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.
