Measurements of changes in ultrasonic velocities and critical angle method signal amplitude have been made on reactor irradiated A302-B, A542-B, and 304 steels. Results show a strong sensitivity to neutron fluence and irradiation temperature. Changes at lower irradiation temperatures appear correlative to some irradiation degraded changes in mechanical properties.
