Neutronbased research begins in the main reaction pool where 72000 gallons of water cool the reactor core and act as a barrier to prevent radiation from escaping into the air. The fission reaction in the core is powered by fuel rods of uranium irconium hydride and is moderated by neutronabsorbing rods of boron carbide. Human operators

Neutronabsorbing panels are generally enclosed within a panel cavity by a wrapper plate that may or may not allow interaction with the water in the spent fuel pool. Therefore the neutronabsorbing materials may be exposed to borated or unborated water or kept dry. These materials may also be exposed to alpha beta gamma and neutron
