W3 CEDM Nozzle Freespan Lengths Kaly, .'

Attached is a table that documents the actual as-built freespan lengths of the Waterford 3 CEDM nozzles. These lengths were determined from the UT scan data. In Entergy letter CNRO-2003-00057, dated 10/24/03, Entergy responded to an NRC question pertaining to reanalysis criterion. In that letter, Entergy provided the amount of freespan length, designated as "minimum propagation length", required for each nozzle group. A nozzle with less freespan length than the designated miminum propagation length would require augmented inspection. As can be seen from the attached table, the actual as-built freespan lengths of the CEDM nozzles exceed the minimum propagation lengths. Therefore, no augmented inspections of the CEDM nozzles were required. Please let me know if you have any questions about this information.

Thanks!
