Early the next morning I was passing through Arco, Idaho about 15 miles from Craters of the Moon. Arco has the distinction of being the first city in the world to receive it's electricity from a nuclear power plant. Experimental Breeder Reactor One (EBR1) is located east of the city and in 1955 it began providing power to the town of Arco.
This was part of a display at the Idaho Science Center. It is all outside and primarily focused on the submarines and the role of nuclear power in warfare. The two granite stones are monuments to submariners and there is some basic information on the torpedo.
