Abstract
A method and apparatus for magnetically determining the Gd.sub.2 O.sub.3 content in UO.sub.2 fuel pellets is described. The alternating current susceptibility of fuel pellets within a zircalloy cladding is measured using an ac inductive technique. Ferromagnetic impurity moments are saturated with a direct current magnetic field. Susceptibility increases with increasing Gd.sub.2 O.sub.3 content when the ferromagnetic component is saturated in fields above 6 kOe.
