Davis-Besse Nuclear Power Station Steam Generator Tube Inspection Report cc: NRC Region III Administrator NRC Resident Inspector NRC Project Manager Utility Radiological Safety Board A ._J Attachment L-12-276 Davis-Besse Nuclear Power Station Steam Generator Tube Inspection Report Page 1 of 28 Following completion of a steam generator inspection performed in accordance with the Davis-Besse Nuclear Power Station (DBNPS) Technical Specification (TS) 5.5.8, "Steam Generator (SG) Program," TS 5.6.6, "Steam Generator Tube Inspection Report," requires a report of the inspection to be submitted to the Nuclear Regulatory Commission within 180 days after the initial entry into MODE 4. This report summarizes the steam generator tube inspection performed during the DBNPS spring 2012 refueling outage.The organization of the report is as follows: Section 1 Scope of Inspections Performed on Each SG (TS 5.6.6.a), Section 2 Active Degradation Mechanisms Found (TS 5.6.6.b), Section 3 Nondestructive Examination Techniques Utilized for Each Degradation Mechanism (TS 5.6.6.c), Section 4 Location, Orientation (if Linear), and Measured Sizes (if Available) of Service Induced Indications (TS 5.6.6.d), Section 5 Number of Tubes Plugged or Repaired During the Inspection Outage for Each Active Degradation Mechanism (TS 5.6.6.e), Section 6 Total Number and Percentage of Tubes Plugged or Repaired to Date (TS 5.6.6.f), Section 7 Results of Condition Monitoring, Including the Results of Tube Pulls and In-situ Testing (TS 5.6.6.g), Section 8 Effective Plugging Percentage for All Plugging and Tube Repairs in Each SG (TS 5.6.6.h), and Section 9 Repair Method Utilized and the Number of Tubes Repaired by Each Repair Method (TS 5.6.6.i).Common acronyms used throuQhout this report%TW Percent Through-Wall AFW Auxiliary Feedwater AX LEN Axial Length of indication in inches CIRC LEN Circumferential Length of tubing circumference of indication in inches DEG MODE Mode of Degradation DEPTH Flaw Depth in Percent of Wall Thickness GMD Geometric Mean Distortion ID Inside Diameter IGA Intergranular Attack IND.

Circumferential PWSCC Attachment L-1 2-276 Page 5 of 28 Section 3 Nondestructive Examination Techniques Utilized for Each Degradation Mechanism (TS 5.6.6.c)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 +PointTM was 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 and wedge)region, non-stress relieved roll transitions, the lower tubesheet crevice region, various dent and wear locations, and other locations with non-quantifiable bobbin signals. These techniques were also used to characterize indications of interest reported by the bobbin technique.

Both+PointTM and bobbin techniques were used to examine tube sleeves. The rotating +PointTM probe was applied to the rolled regions and lower sleeve end while the bobbin probe was used to examine the unrolled portion. 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.

All examination techniques utilized were qualified for detection of the relevant and-potential degradation mechanisms.

This qualification is in accordance with the Electric Power Research Institute (EPRI), "Steam Generator Management Program: Pressurized Water Reactor Steam Generator Examination Guidelines, Revision 7." The applicable examination technique specification sheets (ETSS) are listed for reference only. Site-specific examination technique sheets are developed prior to each steam generator inspection in accordance with Appendix H or I (as applicable) of the EPRI SG examination guidelines.

The SG primary to secondary operational leakage just prior to spring 2012 refueling outage was reported to be very low (not measurable).
Therefore, based on the results of the steam generator tube inspections, both SG 2-A and SG 1-B meet the leakage and structural margins prescribed in the steam generator performance criteria.
Attachment L-12-276 Page 28 of 28 Section 8 The Effective Plugging Percentage for All Plugging and Tube Repairs in Each SG (TS 5.6.6.h)During the spring 2012 refueling outage, tubes that had to be removed from service were removed by plugging.
During previous outages, in some cases, upper tube end or original roll expansion indications were left in service after performing a repair roll expansion to create a new pressure boundary below the indication.
The repair roll process does not remove heat transfer surface area or increase the primary flow resistance.
This repair roll (or reroll) process was not performed during the refueling outage.The process of plugging removes heat transfer area from service and increases primary flow resistance of the steam generator.
Sleeving does increase the primary flow resistance of the steam generator, but has minimal impact on the heat transfer area or efficiency.
The 199 installed sleeves in SG 2-A are equivalent to 30 plugged tubes, and the 212 installed sleeves in SG 1-B are equivalent to 32 plugged tubes. The plugging equivalency for SG 2-A is then 936 tubes (6.1 percent) and for SG 1-B is 578 tubes (3.7 percent).A review was performed and verified that the change is within the analyzed design margins.Therefore, the removal of the heat transfer area and increased flow resistance is within the limits for the total number of tubes allowed to be removed from service (plug equivalents) and does not affect the steam generator's compliance with the design performance requirements.
