Diablo Canyon Power Plant, Unit 2 - Acceptance Review for ASME Section XI ISI Program Relief Request NDE-RCS-SE-2R19 (TAC No. MF5348)

By letter dated December 2, 2014 (ADAMS Accession No. ML14336A607), Pacific Gas and Electric Company submitted a relief request NDE-RCS-SE-2R19 for Diablo Canyon Power Plant (DCPP), Unit 2 Nineteenth refueling outage (2R19). The relief request proposes an alternative to the requirements of American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI, Appendix VIII, Supplements 2 and 10 as modified by ASME Code Case N-695, Qualification Requirements for Dissimilar Metal Piping Welds, and ASME Code Case N-696, Qualification Requirements for Appendix VIII Examinations Conducted from the Inside Surface. Briefly, the reactor vessel nozzle-to-safe end and safe end-to-piping welds will be inspected during DCPP 2R19. The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this relief 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 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 relief 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.
