SUMMARY
REPORT FOR FALL 2004 OUTAGE NORTH ANNA POWER STATION, UNIT 1 VIRGINIA ELECTRIC AND POWER COMPANY By letter dated October 4, 2004, (ADAMS Accession No. ML042780547) as supplemented by letter dated February 21, 2005, (ADAMS Accession No. ML050530049) Virginia Electric and Power Company (the licensee) submitted information pertaining to the steam generator tube inservice inspection performed at North Anna Power Station, Unit 1 during the Fall 2004 refueling outage.
There are three Westinghouse Model 54F replacement steam generators at North Anna, Unit 1, with each steam generator containing 3592 thermally treated Alloy 690 tubes. These Alloy 690 tubes have an outside diameter of 7/8 inch, a wall thickness of 0.050 inch, and are supported by seven stainless steel tube support plates and baffle plate. Most of the tube support plate holes are quatrefoil shaped. The U-bend region of the tubes in rows 1 through 8 were stress relieved after bending.
In its letter dated October 4, 2004, as supplemented by letter dated February 21, 2005, the licensee provided the scope, extent, methods, and results of its steam generator tube inspections. In addition, the licensee described corrective actions (e.g., tube plugging or repair) taken in response to the inspection findings. Based upon a review of the information provided by the licensee, the NRC staff concludes that the licensee provided the information required by the Technical Specifications for North Anna, Unit 1. In addition, the NRC staff concludes that there are no technical issues that warrant follow-up action at this time, since the inspections appear to be consistent with the objective of detecting potential tube degradation and the inspection results appear to be consistent with industry operating experience at similarly designed and operated units.
