Steel workers on top of the huge sphere at West Milton, NY prepare to slid the top plate into place. This plate, which has a circular man-hole in the middle, is pulled with a cable from the gasoline-operated winch at the left. The great steel sphere, 225 feet in diameter, will be used to test a prototype atomic power plant for the U.S. navy Submarine "Sea Wolf." The sphere was constructed by the Chicago Bridge and Iron Company for the AEC, and the atomic power plant is being built by the Knolls Atomic Power Laboratory, operated by the General Electric Company for the Atomic Energy Commission.
