The December 1960 issue of NN, which announced plans to build the MSRE, paired with a still image from a 1969 video on the MSRE produced by ORNL.
By late 1960, when the U.S. Atomic Energy Commission authorized plans to build a Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory, the lab already had about 13 years of experimentation with molten salt reactors under its longest-serving lab director, Alvin Weinberg. The MSRE operated from 1965 to 1969, proving that molten salt reactors could operate reliably, and with alternatives to uranium-235 too.

As an undergraduate I studied physics at the University of Athens. I entered the university in 1955 after successfully passing a national exam (came up fourth in a field of about 700 candidates). Upon graduation and finishing my mandatory two-year military service, the plan was to teach physics either in a public high school or as a tutor for a private for-profit institution, preparing high school students for the national exam.

The Nuclear Regulatory Commission will hold a public meeting on May 8 to discuss the license termination process for the retired nuclear-powered merchant ship, the NS Savannah. During the meeting, NRC staff will discuss the license termination process and receive public comments on the remaining cleanup activities described in the license termination plan for the historic ship, which may see a second life as a floating museum.

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.

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.
