Final Report of the ENIQ 2nd Pilot StudyFunded under: FP6-JRC
The present report gives an overall picture of the ENIQ 2nd Pilot Study, where the potential of technical justifications (TJ) to reduce the number of test piece trials in the qualification of ultrasonic inspection procedures for non-destructive tests was investigated. As the subject of the study a ferritic BWR-type nozzle to shell weld was selected. A TJ, partly relying on mathematical modelling, was produced to predict whether a designated ultrasonic inspection would be successful in detecting the specified defects. In parallel, a test piece with deliberately introduced defects was fabricated and inspected with the inspection system specified in the TJ. Predictions and inspection results were compared. In addition, as a separate exercise, three different mathematical models were used to predict the ultrasonic responses of the defects in the test piece to provide information on model applicability and accuracy of prediction.
