ENIQ 2nd Pilot Study - Compilation of Modelling Results and Comparison with Inspection Data

Funded under: FP6-JRC


The present report compiles the results of the mathematical modelling work carried out in the ENIQ 2nd Pilot Study. As the subject of the study a ferritic BWR-type nozzle to shell weld with deliberately introduced defects was selected. Three different models have been applied to predict the peak amplitude responses of the defects for two different ultrasonic inspection scenarios: i) inspection of the unclad BWR test piece from the inside and ii) inspection of the clad BWR test piece form the outside. The results of the simulations are reported and compared with real inspection data.
