Acceptance Review: NORTH ANNA 1 - RR: Performing a system leakage test of a reactor coolant pressure boundary pipe segment By letter dated May 19, 2015 (Agency-wide Documents and Access Management System (ADAMS)

Accession No. ML15147A016), Virginia Electric and Power Company (the licensee) requested relief related to performing a system leakage test of a reactor coolant pressure boundary pipe segment. The pipe in question is a portion of the auxiliary pressurizer spray line.

Instead of testing in accordance with the system leakage test requirements from ASME Section XI, IWB-5222(b), the licensee proposes to test according to ASME Section XI, Table IWB-2500-1 and IWB-5221, with the isolation valve 1-CH-HCV-1311 in the normally closed position. 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.
