SUBJECT:

CRYSTAL RIVER 3 STEAM GENERATOR TUBE EDDY CURRENT GRAPHIC On October 2, 1996, I had a telephone conversation with a representative from Crystal River Unit 3 to clarify the licensee's July 25, 1996, response to an NRC request for additional information on Generic Letter 95-03. During this telephone call, the licensee faxed an eddy current graphic to illustrate the multiple axial indication that was detected in a non-stress relieved expansion transition. This indication was described in the above referenced letter. A copy of this graphic is attached. The multiple axial indication is not associated with the bottom of either the original roll expansion or the re-rolled expansion. The licensee representative also indicated that of the approximately 14,000 tubes which had the tube ends repaired, approximately 480 of those tubes had been rerolled and are currently (1996) in service. The tube end repair process is discussed in the above referenced letter.
