Acceptance Review: NORTH ANNA 2 - AC Source-Operating Revised Surveillance Requirement -TS 3.8.1 By letter dated May 22, 2015, Virginia Electric and Power Company (Licensee) submitted a license amendment request (LAR) to revise Technical Specification (TS) to AC Source-Operating Revised Surveillance Requirement -TS 3.8.1. The TS 3.8.1, "AC Sources - Operating", contains SR 3.8.1.8, which requires verification of the capability to manually transfer Unit 1 4.16 kV ESF bus AC power sources from the normal offsite circuit to the alternate required offsite circuit. As currently stated in SR 3.8.1.8 Note 1 and the TS Bases, this SR is only applicable to Unit 1 because it does not have an alternate offsite power feed for the ESF buses. However, Dominion is developing a plant modification to install an alternate offsite power feed to each of the Unit 2 4.16 kV ESF buses such that the final configuration for Unit 2 will be similar to the existing Unit 1 configuration. Therefore, a change is proposed to delete SR 3.8.1.8 Note 1, thereby eliminating the limitation that excludes Unit 2 from the manual transfer verification requirement of SR 3.8.1.8. The purpose of this email is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this LAR. 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 application 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 request 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 staffs 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 301-415-2597.
