Given its good absorption cross section for thermal neutrons, excellent mechanical properties and extremely high corrosion resistance, hafnium is used for nuclear reactor control rods.
S obzirom na dobru poprečnu apsorpciju termalnih neutrona, odlična mehanička svojstva i izuzetno visoku otpornost na koroziju, hafnijum se koristi za izradu kontrolnih šipki u nuklearnim reaktorima.
