Experimental Breeder Reactor 1, ID-7087042
U.S. National Historic Landmark located in the desert about 18 miles southeast of Arco, Idaho.
On November 29, 1955, the reactor at EBR-I suffered a partial meltdown during a coolant flow test. The flow test was trying to determine the cause of unexpected reactor responses to changes in coolant flow. It was subsequently repaired for further experiments, which determined that thermal expansion of the fuel rods and the thick plates supporting the fuel rods was the cause of the unexpected reactor response.
EBR-I was deactivated by Argonne National Laboratory in 1964 and replaced with a new reactor, Experimental Breeder Reactor II.
It was declared a National Historic Landmark in 1965.
