i Docket Number 50-346 License Number NPF-3 Serial Number 2944 Page 1 TECHNICAL SPECIFICATION REPORTING REQUIREMENTS Eddy Current Examination Techniques The tubing in the Once Through Steam Generators (OTSG's) at the Davis-Besse Nuclear Power Station Unit #1 was examined in February and March, 2002, during the 13th Refueling Outage. The examinations were conducted by Framatome Technologies to meet the requirements of the Davis-Besse Unit #1 Technical Specifications.
The eddy current examinations were performed utilizing various eddy current probes.
The bobbin coil technique was used to perform the standard ASME Code examination for flaw detection. This technique was applied to the complete length of all in-service tubes. The rotating plus point and pancake techniques (RPP) were used to examine specific areas of interest. These areas included upper tube end roll expansion regions, critical areas of tubes bordering the sleeved (lane & wedge) region, non-stress relieved roll transitions, the lower tubesheet crevice region and select dent locations. These techniques were also used to characterize all indications reported by the bobbin technique and the pancake coil was used to provide final depth sizing of Tube Support Plate wear indications. Both plus point and bobbin techniques were used to examine tube sleeves. The rotating plus point probe was applied to the rolled regions and lower sleeve end while the bobbin probe was used to examine the unrolled portion. The rotating plus point technique was used to examine plugs. contains the Eddy Current Identification Codes used in the tables in this attachment.
