1.0 General

Information This report describes the Inservice Inspection of Duke's Oconee Nuclear Station, Unit 2, during Outage 4/EOC 24. This is the second outage in the second inspection period of the Fourth Ten-Year Interval.

ASME Section XI, 1998 Edition with the 2000 Addenda, was the governing Code for selection and performance of the ISI examinations.

Included in this report are: the inspection status for each examination category, the final inservice inspection plan, the inspection results for each item examined, and corrective actions taken when reportable conditions were found. In addition, there is an Owner's Report for Repair/Replacement Activities Section, which includes completed NIS-2 documentation of repair/replacement activities.

1.2 Reference

Documents The following reference documents apply to the inservice inspections performed during this report period. A copy may be obtained by contacting the ISI Plan Manager at Duke's Corporate Office in Charlotte, North Carolina.Code Case N-460 (Alternative Examination Coverage for Class 1 and Class 2 Welds,Section XI, Division I) Applicable to items in this report where less than 100% coverage of the required weld examination volume was achieved.Code Case N-504-2 (Alternative Rules for Repair of Class 1, 2, and 3 Austenitic Stainless Steel Piping). Applicable to items that receive a weld overlay. During 2EOC-24 outage there were welds that received weld overlay and the PSI exams were performed per Code Case N-504-2.Code Case N-609 (Alternate Requirements to Stress-Based Selection Criteria for Category B-J Welds,Section XI, Division 1.)Code Case N-624 (Alternative to the requirements of IWB-2420(a), IWC-2420(a), IWD-2420(a), and IWF-2420(a).)

This will allow the sequence of component examinations that were established during the first inspection interval to be modified, provided that the percentage requirements are still met.Code Case N-663 (Alternative Requirements for Classes 1 and 2 Surface Examinations,Section XI, Division, I)Code Case N-685 (Lighting Requirements for Surface Examinations)

Code Case N-695 (Qualification Requirements for Dissimilar Metal Piping Welds,Section XI, Division I)Code Case N-722 (Additional Examinations for PWR Pressure retaining Welds in Class 1 Components Fabricated with Alloy 600/82/182 MaterialsSection XI, Division 1) 1 OCFR Part 50, Federal Register, Final Rule that was issued September 10, 2008 mandates the use of this code case.

This PIP was written to track the evaluation process and resolution for limited coverage on UT examinations of welds that were inspected during EOC-24 for Unit 2. This will include processing relief request if it is determined that greater than ninety percent of coverage cannot be achieved.

The welds with limited coverage are listed in Section 4.4 of this report.PIP 0-09-00530 was written to document the work orders that had work completed during the 2EOC-23 report period but the documentation was not completed in time for the NIS-2 forms to be incorporated into 2EOC-23 report.PIP 0-09-0848 was written to incorporate Code Case N-609 into the Fourth Interval ISI Plan. This code case is instrumental in removing stress welds from the inspection plan.PIP G-08-0185 was written to incorporate Code Case N-663 into the Fourth Interval ISI Plan. This code case is instrumental in removing surface exams from the inspection plan.Plan Addenda ONS2-079, ONS2-089, ONS2-091, ONS2-092, and ONS2-096 are instrumental to making changes to the Unit 2 Fourth Interval ISI Plan, which are reflected in the totals shown in the tables in Section 2.Request for Relief 03-006 (Allows Duke an Alternative for the Snubber Examinations required in IWF-5000 for the 4 th interval.)

4.0 Results

Of Insipections Performed The results of each examination shown in the final Inservice Inspection Plan (Section 3 of this report) are included in this section. The completion date and status for each examination are shown. All examinations revealing reportable indications and any corrective action required as a result are described in further detail in Subsections 4.1 and 4.2. Corrective measures performed and limited examinations are described in further detail in Subsections 4.3 and 4.4.4.1 Reportable Indications EOC 24 (Outage 4) did not have any reportable indications during this report period.4.2 Corrective Action Corrective action is action taken to resolve flaws and relevant conditions, including supplemental examinations, analytical evaluations, repair / replacement activities, and corrective measures.

There were no problems that required corrective action during this report period.4.3 Corrective Measures Corrective measures are actions (such as maintenance) taken to resolve relevant conditions, but not including supplemental examinations, analytical evaluations, and repair / replacement activities.

Any corrective measures performed for examinations associated with this report period will be shown on the examination data sheets which are on file at the Duke's Corporate Office in Charlotte, North Carolina.EOC 24 Refueling Outage Report Oconee Unit 2 Section 4 Page 1 of 2 Revision 0 July 14, 2010

PIP 0-09-00530 was written to document that work orders 1762586 and 1779633 had work completed during 2EOC-23, but the documentation was not completed in time for the NIS-2 forms to be incorporated into 2EOC-23 report.The individual work request documents and manufacturers' data reports are on file at Oconee Nuclear Station. /5.1 Class 1 and 2 Preservice Examinations As required by the applicable code, Preservice Inspection (PSI) Examinations were performed on ISI Class land Class 2 items during this report period. PSI Examination data for items listed below is on file in the Oconee Nuclear Station QA Vault.Work Order 1869317 was written to apply weld overlay on a Class 1 drain nozzle to safe-end weld in system 51A. A PSI UT exam was performed on the weld overlay (Weld # 2-51A-0035-136V).

In addition to the information above, there is a list for PSI exams that were performed and the list is located behind the NIS-2 forms in this section. The list has one page and is entitled "Preservice Examinations of Class 1 & 2 Welds".PSI examination data for items on the list previously mentioned is on file in the Oconee Nuclear Station QA Vault.EOC 24 Refueling Outage Report Oconee Unit 2 Section 5 Page 1 of 1 Revision 0 July 14, 2010 Form NIS-2 Owner's Report for Repair/Replacement Activity As required by the provisions of the ASME Code Section XI U.S Work Order Number 1 1780230 Sheet 1 of 3 1.
