Description

Graphite from Chicago Pile-1—Fermi's research reactor that launched the nuclear age

Graphite disc from Chicago Pile-1 (CP-1), the first nuclear energy reactor which launched the first successful experiment in atomic energy, giving life to the nuclear age. The graphite is encased in an acrylic dome, measuring approximately 2.5˝ x 1.25˝, identified with impressed text: "Graphite From First Chain Reactor, 12-2-42." In fine condition.

Enrico Fermi led the experiment at the University of Chicago on December 2, 1942, which used uranium as fuel and ultra-pure graphite as a neutron moderator. Critical mass for a self-sustaining reaction was reached at 3:25 PM, lasting for 28 minutes. Throughout the 1960s, pieces of the graphite from CP-1 were awarded to important dignitaries and scientists who had worked on the project.
