Which of the following minerals is used in nuclear reactors?
-
Zircon
-
Manganese ore
-
Mica
-
Bauxite
A
Correct answer
Explanation
Zircon (zirconium) is used in nuclear reactors because zirconium alloys have very low neutron absorption cross-sections, allowing neutrons to pass through and sustain the nuclear fission chain reaction. Zirconium cladding also provides excellent corrosion resistance in high-temperature reactor environments, making it ideal for fuel rod casing.
