Chicago Pile 1 (CP-1) Fermi Pile Graphite

Description

If you are looking at this you know what it is and the amazing American History that it represents as the first major achievement of the Manhattan Project.
“On December 2, 1942, man achieved here the first self-sustaining chain reaction and thereby initiated the controlled use of nuclear energy.”
This is a section of the very high purity graphite used in the Chicago Pile-1 graphite-moderated reactor.  CP-1 was the first man-made reactor to achieve and sustain criticality on December 2, 1942, nearly one year after the Japanese attack on Pearl Harbor.  The reactor was located under the abandoned racket court at Stagg Field at the University of Chicago campus.
This graphite was developed by Union Carbide under the consult of Enrico Fermi (1938 Nobel Prize in physics) and Leo Szilard.  It is the world's first nuclear-grade graphite, free of neutron-absorbing boron impurities.  Walter Zinn, the first president of the American Nuclear Society (ANS abbreviation in the Lucite) led the team that machined the graphite moderator blocks for CP-1.
This type of graphite was used at Oak Ridge and Hanford for the production of plutonium during and after WWII.
If you want more information on this graphite, you can read about it here:  https://en.wikipedia.org/wiki/Chicago_Pile-1 and here  https://en.wikipedia.org/wiki/Nuclear_graphite
As you know it is almost impossible to find a piece of the CP-1 graphite moderator, and when you do find them they are rarely for sale.  The last piece that I saw for sale was ,500.
The graphite is not radioactive above background radiation.
I will insure the shipment for the full value of the sale.  I will ship to you by least expensive carrier, least expensive method, fully insured.  I never charge handling fees.
I am the original owner of this piece of history.  I was a member of the American Nuclear Society in the 1980s and 1990s and purchased this item directly from ANS.
