Docket Number 50-346 License Number NPF-3 Serial Number 3288 Attachment 1 Page 1 of 29 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 March, 2006, during the 14th 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 American Society of Mechanical Engineers (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, upper tubesheet crevice region, 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 indications of interest reported by the bobbin technique. Both bobbin coil and the pancake coil were used to provide depth sizing of Tube Support Plate wear indications. The largest Tube Support Plate wear indication depths from either technique are reported. 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. contains the Eddy Current Identification Codes used in the tables in this attachment.
