    First Controlled Nuclear chain reaction
    Control Rods Source Fermi, at The University of Chicago created a controlled juclear chain reaction. He used Cadmium rods to absorb the neutrons and was able to use the rods to regulated the speed of fission and was able to create a self-sustaining chain reaction that provided a steady source of energy.
