The European network for inspection qualification (ENIQ) published at the beginning of 1997 the second issue of the European methodology for qualification of nondestructive testing (NDT). A pilot study is currently being carried out to explore the issues involved through the practical application of the European methodology. The components selected for the pilot study are austenitic pipe to pipe and pipe to elbows welds typical of those in boiling water reactor (BWR) recirculation loops. A range of defect parameters has been defined. A suitable inspection procedure designed to find the designated defects will be applied to geometrically representative test pieces. The procedure/equipment was qualified through open trials and technical justification. The personnel qualification was done in a blind way. One all features of the inspection system were qualified, an in-service inspection was simulated in order to test the feasibility of the qualification approach followed. In this paper the current status of this pilot study and the main lessons learned will be discussed.
