|Abstract:||This document compiles the results of the defect assessment and destructive examination carried out to determine the true dimensions and orientations of the defects, which have been deliberately implanted into the ENIQ nozzle assembly 21. Two different fabrication techniques have been used to implant the defects. Both surface breaking and near surface defects were produced by spark erosion using an electrode with a sharp tip. These are so-called PISC type A defects, and silica based replicas were taken on each defect after manufacturing. The silica based replicas were examined by the JRC, Institute for Energy in Petten. The second group of defects are located on the weld fusion faces and are embedded in the base material. These sidewall lack of fusion defects, which were produced by means of the so-called coupon technique, have been destructively examined by the Nuclear Research Institute (NRI) Rez.|
