Nonlinear Ultrasonic Characterization of Radiation Damage in Ferritic Reactor Pressure Vessel Steel
As many U.S. nuclear plants enter extended operations, radiation damage is a critical concern. This research investigates the ability of a nondestructive evaluation technique called nonlinear ultrasound to characterize radiation damage in reactor pressure vessel steels over a range of fluence levels (a measure of neutron exposure), irradiation temperatures, and material composition.
