[en] A number of tubes were removed from Pickering Unit 8 due to excessive depth of fretting damage at dummy fuel bearing pad positions. Fifteen of these tubes were designated for destructive examination at three sites: AECL-CO, OHRD and CRNL. Examination of parts of six tubes from channels E08, F15, G10, J12, K18 and L14 were carried out at OHRD. The objective of the examination was to determine the extent of microcracking in the fret zones and to confirm the previously observed hydride distributions near fret marks. Results of the investigation show that there is no significant microcracking at the fret marks. However, secondary marks probably due to fretting by particles in the PHT coolant being trapped near bearing pads or under bundles, have been identified. These marks were studied in detail to determine their shapes for subsequent stress analysis. This report summarizes all these examinations
