Advanced ultrasonic inspections
Acoustic emission (AE) continuous monitoring and periodic inspections by advanced ultrasonics were applied to evaluate defect evolution within a PWR reduced scale (1:5) pressure vessel subjected to cyclic mechanical fatigue. Assessment of defect evolution was achieved by multifrequency acoustic holography. Attention was focussed on areas located along the fabrication welds where defects were located. Defect characterisation, sizing and 3D representation were performed, and the results obtained were compared with previous inspections.
