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.

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.

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.

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.
