Introduction:==

The code of record for the second inspection interval which began December 16, 1995 is the 1989 Edition of the ASME Boiler and Pressure Vessel Code, Section Xl, Division 1.

The Unit 1 Cycle 11 inservice examinations were performed during the period from March 18, 2000 to November 22, 2001. This report also includes repairs and replacements performed during this period from March 18, 2000 to November 22, 2001. The Unit 1 Cycle 11 Refueling Outage began when the generator was taken off line on October 21, 2001. The outage was completed on November 22, 2001, when the generator was tied to the power grid. The inservice examinations were performed to the implementing plant Surveillance Instruction 0-SI-DXI-000-1 14.2, "ASME Section XI ISI/NDE Program Unit 1 and Unit 2" revisions 12 and 13. The steam generator tubing eddy current examinations are discussed in Appendix A, repairs and replacements are discussed in Appendix B, pressure test examinations are discussed in Appendix C, this also includes pressure tests performed during the second interval that were not included in previous reports, and the IWE metal containment evaluations are discussed in Appendix D. Examinations performed during this cycle satisfy the inspection requirements for the second outage of the second period of the second 10 year interval as defined in the 0-SI-DXI-000-114.2.

The Authorized Inspection Agency (AIA), Hartford Steam Boiler Inspection and Insurance Company of Connecticut (HSB CT), provided the following ANIIs:

Unit 1 Cycle 11 was the second scheduled refueling outage during the second inspection period of the second Ten Year ISI interval. Class 1 and 2 components were examined in accordance with O-SI-DXI-000-1 14.2, "ASME Section Xl ISI/NDE Program Unit 1 and Unit 2". A summary listing of examinations performed for code credit are listed in SECTION 1. The examinations were performed to TVA approved procedures. The class 1 and 2 components examined and results for this inservice inspection outage are listed in SECTION 2. There were seven Notice of Indications generated for ASME Section XI, Class 1 and 2 examinations. See SECTION 3 for notice of indications summary. See SECTION 4 for additional samples summary. See SECTION 5 for successive examinations summary. No regulatory required augmented examinations were performed which require submittal to the regulatory authority (Reference SECTION 6). There were no new ASME Class 1, 2, or 3 equivalent components for which examination results required acceptance by analytical evaluation (IWB-3132.4, IWB-3142.4, IWC-3122.4, IWC-3132.4 or IWD-3000). (Reference SECTION 7). There were two components which did not receive the code required examination coverage (see SECTION 8).

For Unit 1 Cycle 11 steam generator tubing eddy current examinations results and number of tubes examined see Appendix A.

For repairs and replacements performed see Appendix B.

For Unit 1 Cycle 11 pressure test results and second interval system pressure tests not included in previous reports see Appendix C.

1. Credit taken only for the studs on 2 of the valves examined in B-G-2 during UIC8.

2. Piping modification in U1C10 of the second period added 12 B-J welds to the total number required for the interval increased from 247 to 259.

3. Due to piping modifications in the second period and the increase in the total number required in B-J for the interval these welds were added over the three periods - (4) first, (3) second, (5) third. The 4 welds in the first period are counted as credit for the interval.

PART I1- DISPOSITION, page 1 of 2 This NOI documents the indications noted during the VT-3 visual examinations of the Steel Containment Vessel (SCV) exterior surface areas. The areas examined have been identified for coating repair, and this VT-3 visual examination was performed prior to surface preparation to satisfy the requirements of IWE-2500(b). The examination identified indications consisting of heavy rust and exfoliation, however upon further review, it was deemed to be minor rusting and discoloration after cleaning. The containment surfaces examined are identified on the listed examination reports and were visually inspected and evaluated after surface preparation. The SCV surface, stiffeners, and penetrations showed minor corrosion and pitting, with no visible signs of active corrosion. The surface condition (minor corrosion and pitting) appeared to be

- pitting from original construction. The area above penetration X-145E that showed signs of distress (metal protrusion) was apparently the result of welding the ice condenser seal attachment steel on the inside of the SCV. This area was ultrasonically examined for thickness which showed minor variations in thickness. The area was also magnetic particle examined with no identified indications. These areas are not considered suspect and do not impact the structural integrity or leak tightness of the SCV. No detrimental flaws were observed. These areas willbe re-coated according to site procedure M&AI-5.3 (WO 01-001081-000). A VT-3 preservice examination will be performed on these areas following reapplication of the coatings to satisfy the requirements of IWE-220 . The component is acceptable for continued service, and no further v o "

This NOI documents the indications noted during the VT-3 visual examination of the SCV exterior surface areas from horizontal stiffener G to horizontal J, and vertical stiffeners 1 through 90.

A VT-3 preservice examination will be performed on these areas following reapplication of the coatings to satisfy the requirements of IWE-2200(g). Te component is acceptable for continued service, and no further corrective action is required. Therefore, Ed6ditiohal examinations are not warranted.
