Chicago Pile-3 (CP-3) was a nuclear reactor that was part of the Manhattan Project during World War II. It was constructed at the University of Chicago and became operational in 1944. CP-3 was the first reactor to use uranium fuel enriched above the levels used in earlier reactors, making it a significant step in the development of nuclear technology.
