U.S. Nuclear Regulatory Commission Page 2 JAN 2 6 2007 This letter provides the WBN Unit 1 60-day response to the reporting requirements listed in Section IV, Paragraph E of the First Revised NRC Order EA-03-009 dated February 20, 2004.
TVA consented to the First Revised Order for WBN in the Reference 3 letter. provides excerpts from the report entitled, "Watts Bar Unit 1, Cycle 07 Reactor Pressure Vessel Closure Head and Lower Head Remote Visual (VT-2)
Examination Final Report -
September 2006)"
which documents the complete inspection of the reactor pressure vessel (RPV) closure head and lower head.
The excerpts included in provide the details of the inspection results for the RPV closure head.
This is the second bare metal visual inspection of the RPV closure head performed in accordance with NRC Order EA-03-009.
The results of the first bare metal inspection of the RPV were provided in the Reference 1 letter.
Section IV, Paragraph C(3) of the subject order for plants that fall within the low susceptibility category require a bare metal visual examination of 100 percent of the RPV head surface (including 360 degrees around each RPV head penetration nozzle) at least every third refueling outage or every 5 years.
The results of the WBN Unit 1 Cycle 7 outage inspection identified that no penetration indicated boron leakage in the area of the annulus associated with inside surface CRDM weld cracking.
In addition, no boron was noted on the head surface with the origination point being from the penetrations.
Each penetration was accessible and satisfactorily examined.
Details of the closure head visual examination are provided in.
There are no regulatory commitments associated with this submittal.
If you have any questions concerning this matter, please call me at (423) 365-1824.

Watts Bar Unit 1, Cycle 7 - RPV Closure Head REPORT Remote Visual (VT-2) Penetration Examination Final Report Visual Examination Report Summary INTRODUCTION During the Watts Bar Unit 1, Cycle 7 Refueling Outage, remote visual (VT) examinations were performed on the outside surface of the Reactor Pressure Vessel (RPV) Closure Head and penetrations. The examinations were performed from September 17 - 18, 2006 by Tennessee Valley Authority's (TVA's) Inspection Services Organization (ISO) and Vistas Corporation.
SUMMARY
The VT examinations were accomplished to address the integrity of the RPV closure head penetrations, including the Control Rod Drive mechanisms (CRD's), Upper Head Injection (UHI) and the Vent line. A total of 83 penetrations were examined, including (78) CRD's, (4) UHI's and (1) Vent line. The examinations were performed to address NRC Order EA-03-009, "Interim Inspection Requirements for Reactor Pressure Vessel Heads At Pressurized Water Reactors". The examination scenario was aimed at determining whether boric acid deposits were emanating from the annulus of the penetrations and identifying the presence of boric acid deposits on the RPV head.
The work was performed as part of the WEN/ISI program, augmented exam section, of 1-TRI-0-1 0, revision 13. In addition, the examinations fulfill NRC Order EA-03-009, Section 3 (a), Bare Metal Visual Examination of 100% of the RPV head penetration nozzles and surrounding head surface.

Watts Bar Unit 1, Cycle 7 - RPV Closure Head REPORT Remote Visual (VT-2) Penetration Examination Final Report TECHNICAL DISCUSSION Remote VT Equipment TVA contracted with Vistas Corporation to provide remote VT equipment to examine the RPV head penetrations. The remote examinations were performed with Vista's magnetic crawlers, outfitted with twin high resolution color cameras, each having adjustable LED lighting arrays. The cameras were located on the front and rear of the remote crawlers.
Access to the examination area was obtained by lifting the insulation shroud approximately 5 inches from the vessel head and installing temporary wooden wedges for stabilization.
The remote crawler was installed on the head surface and guided between the rows of penetrations.
The examinations were recorded on Digital 8 video cassette's for archival and off-line review. All penetration annulus areas and the head surface in the area on the penetrations were examined and digitally recorded.
Procedure/Documentation ISO provided Level IIl's certified in Visual examination to review and evaluate all data on-line. All acquired data also had an independent review by certified Level III VT examination personnel. Examination protocol was designed to incorporate the recommendations of the Electric Power Research Institute's (EPRI) Technical Report, entitled "Visual Examination for Leakage of PWR Reactor Head Penetrations on Top of RPV Head", Revision 2 of 1006296, including 2002 Inspection Results. The examination was conducted in accordance with TVA's Nondestructive Examination (NDE) Procedure N-VT-1 7, Revision 4, "Visual Examination for Leakage of PWR Head Penetrations".
The visual examination process utilized enhanced VT-2 methodology with camera resolution established on characters less than or equal to.105" high, representative of VT-3 sensitivity.

Watts Bar Unit 1, Cycle 7 - RPV Closure Head REPORT Remote Visual (VT-2) Penetration Examination Final Report Examination Process An examination Scan Plan was developed in order to ensure that examinations were performed in a logical sequence, while minimizing radiation exposure and validating positional accuracy. A raster pattern was chosen as the most effective method for performing the examinations and consisted of 22 separate scans.
A total of 323 sequences were performed to examine all penetrations. With the exception of the outer scan rows, each penetration was examined during two scans which consisted of examining four, 90-degree + segments of each penetration to ensure 100% coverage of the annulus area. The outer scan rows, that included the peripheral penetrations, were examined using two scans that covered 180-degrees + of the penetration that resulted in 100% coverage. During the examination of each penetration, the head area adjacent to the penetrations was also visually examined for boron deposits.
Radiation work permit number 8071 was used for the inspection work. The data acquisition equipment staging area was located on top of Reactor Coolant Pump Plug No.2.
RESULTS No penetrations indicated boron leakage in the area of the annulus associated with inside surface CRDM weld cracking. In addition, no boron was noted on the head surface with the origination point being from the penetration(s). All penetrations were satisfactorily examined. All penetrations were accessible with the Vista's magnetic crawlers.
