STATUS ON THE ENIQ PILOT STUDY TO VERIFY THE FEASIBILITY OF THE EUROPEAN METHODOLOGY FOR INSPECTION QUALIFICATION

摘要

A pilot study is currently being carried out by ENIQ in order to explore the issues involved in inspection qualification applied along the general principles 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 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. An in-service inspection will be simulated in order to test the feasibility of the qualification approach followed. In this paper the current status of this pilot study is discussed.
