Questions & Answers

Q: What is the significance of the graphite in the box?

The graphite is from the world's first nuclear reactor, built as part of a race to develop an atom bomb and prove the viability of nuclear reactors.

Q: How was the graphite used in the reactor?

The graphite blocks were used as a moderator, slowing down the neutrons and facilitating the fission of uranium atoms.

Q: Why was silver chosen as part of the control rods?

Silver can absorb neutrons and become radioactive, allowing it to act as a neutron meter to measure the reactions taking place in the reactor.

Q: What was done to prevent a catastrophic explosion during the reactor's operation?

Control rods, made of a mixture of cadmium, indium, and silver, were used to absorb neutrons and prevent an uncontrolled chain reaction.

Summary & Key Takeaways

• The black piece inside the box is graphite from the world's first nuclear reactor, built in Chicago in 1942.

• The reactor was a pile of graphite blocks with uranium and control rods to regulate the reaction.

• The graphite is symbolic of the nuclear age and the development of nuclear weapons and power stations.
