North Anna Power Station, Unit No. 1, Accept ance Review of Use of Weld Overlays as an Alternative Repair Technique for Steam G enerator Hot Leg Nozzles (N1-I4-CMP-001)

Dear Mr. Heacock:

By letter dated March 30, 2011, Virginia Electric Power Company submitted a request for authorization to use an alternate repair technique for North Anna Power Station, Unit 1. The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's acceptance review of this request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

The NRC staff has reviewed your request and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staff's ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.

If you have any questions, please contact me at (301) 415-6606.
