Acceptance Review of TMI-1 Relief Request RR-10-02, Weld Overlay of Pressurizer Spray Nozzle Welds - TAC No. ME4795 By letter dated September 30, 2010 (Agencywide Documents Access and Management System Accession No. ML102740532), Exelon Generation Company, LLC submitted Relief Request RR-10-02, regarding a proposed alternative request to perform a weld overlay of the Three Mile Island Nuclear Station, Unit 1, pressurizer spray nozzle to safe-end and safe-end to elbow dissimilar metal welds.

The purpose of this email is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's acceptance review of Relief Request RR-10-02. 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 submittal and concluded that Relief Request RR-10-02 does provide technical information in sufficient detail to enable the NRC staff to continue with 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.
