Cadmium is not used for nuclear fuel cladding because of its very high thermal neutron absorption cross-section. Materials used for cladding must have a low neutron absorption cross-section to allow the nuclear reaction to continue efficiently. Instead of being a cladding material, cadmium is used to make control rods for nuclear reactors, where its ability to absorb neutrons is desirable for controlling the rate of the nuclear reaction.
Which of the following is not used as a nuclear fuel cladding material?
