Zirconium alloys
Used for cladding fuel rods due to low neutron absorption cross-section and good chemical stability.
Uranium-235 (U-235)
A fissile material used as fuel, can sustain a nuclear chain reaction.
Heavy Water (D2O)
Used as a neutron moderator and coolant in some reactors; has a lower neutron absorption cross-section than regular water.
Plutonium-239 (Pu-239)
Another fissile material produced from U-238 in reactors; used in some fuel types and weapons.
Graphite
Moderator material that slows down neutrons to thermal energies, increasing the likelihood of U-235 fission.
Control rods materials (Boron, Hafnium, Cadmium)
Materials with high neutron absorption used to control the fission rate in reactors.
