v TXU TXX-03064 Page 2 of 3 and Enclosure 2 of this letter, the reports titled SG-SGDA-02-43-P and SG-SGDA-03-P, contain information proprietary to Westinghouse Electric Company LLC ("Westinghouse") and are supported by an affidavit signed by Westinghouse, the owner of the information. This affidavit sets forth the basis on which the information may be withheld from public disclosure by the NRC and addresses with specificity the consideration listed in paragraph (b)(4) of Section 2.790 of the 10 CFR 50. and Enclosure 4 of this letter, the reports titled SG-SGDA-02-43-NP and SG-SGDA-03-NP, contain non-proprietary versions of Enclosures 1 and 2, respectively. contains the Westinghouse authorization letter, CAW-03-1608, accompanying affidavit, Proprietary Information Notice, and Copyright Notice.
Accordingly, it is requested that the information which is proprietary to Westinghouse be withheld from public disclosure in accordance with 10 CFR Section 2.790 of the Commission's regulations.
Correspondence with respect to the copyright or proprietary aspects of the enclosed Westinghouse documents or the supporting Westinghouse affidavit should reference CAW-03-1608 and should be addressed to H.A. Sepp, Manager of Regulatory and Licensing Engineering, Westinghouse Electric Company, P.O. Box 355, Pittsburgh, Pennsylvania 15230-0355.
Should you require any other additional information please contact Mr. Bob Kidwell at (254) 897-5310.
This communication contains the following new commitment which will be completed as noted:
Commitment Number Commitment 27280 A C-3 condition was reported in SGs 2, 3, and 4 due to the detection of >45 circumferentially oriented ODSCC indications. The 1RF10 top of tubesheet +Pt inspection program will include 20% of the cold leg TTS expansion transitions in these SGs.
The commitment number is used by TXU Energy for the internal tracking of CPSES commitments.

Jaffe, NRR Resident Inspectors, CPSES to TXX-03064 Page 1 of 14 TXU ELECTRIC COMANCHE PEAK STEAM ELECTRIC STATION - UNIT 1 SPECIAL REPORT NO. 1-SR-03-001-00 UNIT 1, NINTH REFUELING OUTAGE STEAM GENERATOR TUBE INSPECTION RESULTS TECHNICAL SPECIFICATION 5.6.10.b to TXX-03064 Page 2 of 14 CPSES 1RF09 Initial Inspection Plan The CPSES 1RF09 inspection plan exceeded both the Technical Specification minimum requirements as well as the recommendations of EPRI TR-107569-V1R5, PWR Steam Generator Examination Guidelines, Revision 5, Volume 1: Requirements. The 1RF09 initial inspection plan included;
- 1. 100% full length bobbin examination in Rows 3 and greater in all 4 SGs, 100% bobbin inspection in the hot and cold leg straight sections of Rows 1 and 2
- 3. from +3 to -3" for hardroll expanded tubes
- 4. from +3 to hot leg tube end for WEXTEX expanded tubes
- 5. 100% Row 1 and 2 U-bend mid-range +Pt examination in all 4 SGs
- 6. Rotating probe examination of mixed residuals (> 1.5 volts as measured by bobbin) and hot leg dented intersections > 5 volts (as measured by bobbin) according to the requirements of GL 95-05.
- 7. Rotating probe examination of freespan bobbin coil indications for flaw confirmation and characterization.
- 9.
100% +Pt inspection of >5V hot leg dings from HTS to AV2 and >5V cold leg dings from CTS to C8, plus 20% +Pt inspection of freespan dings > 5 volts between AV2 and AV3 and C8 and C9.
- 10. 20% +Pt freespan paired ding inspection between the top 2 TSPs
- 11. Tube plug visual inspection The inspection plan was developed to specifically address the areas of active degradation as well as areas expected to be affected based on recent industry experience as well as experience from the CPSES 1RF08 outage in April 2001.
A C-3 condition was reported in SGs 2, 3, and 4 due to the detection of >45 circumferentially oriented ODSCC indications. The 1RF10 top of tubesheet +Pt inspection program will include 20% of the cold leg TTS expansion transitions in these SGs.
Based on the observed 1RF08 eddy current signals from the leaking tube, observation of axial ODSCC in a 6.2 volt ding within the critical area, and observation of axial ODSCC in small dings adjacent to >5V dings, the >5V ding +Pt program was expanded to include all >5V dings, at all locations. Additionally, 100% of the U-bend FSD signals and 20% of the >2 volt dents/dings between CI 1 and AV2 were inspected with +Pt. Another 20% sample of the dents/dings >0.75 volt and <5 volt within 0.75" of structures were also examined with +Pt.
