Abstract

A non-destructive method for the determination of hafnium in zirconium and various alloys, based on the formation of178mHf and179mHf, is proposed. For a neutron flux of 109 n th ·cm−2·sec−1, the limit of determination is about 0.5 μg. This limit can fall to 50 ng with the multiple irradiation runs system (ten runs at 92-second cycles). The simple determination is complete within 15 minutes, whereas the multiple irradiation runs method requires about 15 minutes longer time.
