The year is 1951. End tables were molded plywood, often in wavy, kidney shapes, couches were hard, peg-leg rectangles, televisions were small, oval, black-and- white screens with innards powered by tubes, and Fiesta Ware was the king of the table. Patti Page had a number 1 hit with "Tennessee Waltz," the Korean War was in full swing, and the Catcher In the Rye was first published.
And the first nuclear reactor generated electricity by lighting four light bulbs.
A short video is shown in a 50's living room mock up:
NO, JOHN, NO!!!
This is the reactor itself. The rods were lowered through what is now a plexiglass circle in the center.
