Acceptance Review - Relief Requests NDE-SLH U2, NDE-LSL U2, NDE-LHC U2, NDE-

LHM U2, and NDE-ONV U2, Diablo Canyon Power Plant, Unit 2 (CAC Nos. MF9386 through MF9390)

By letter dated March 8, 2017 (Agencywide Acce ss and management System (ADAMS) Accession No. ML17068A082), Pacific Gas and Electric Company (the licensee) submitted relief requests NDE-SLH U2, NDE-LSL U2, NDE-LHC U2, NDE-LHM U2, and NDE-ONV U2, for relief from American Society of Mechanical Engineers Boiler and Pressure Vessel Code,Section XI full examination volume coverage requirements for reactor pressure vessel welds. 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 amendment request. The acceptance review was performed to determine if there is sufficient te chnical 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 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 te chnical review are identified despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated that this licensing request will take approximately 350 hours0.00405 days <br />0.0972 hours <br />5.787037e-4 weeks <br />1.33175e-4 months <br /> to complete (70 hours8.101852e-4 days <br />0.0194 hours <br />1.157407e-4 weeks <br />2.6635e-5 months <br /> for each relief request). The NRC staff expects to complete this review by January 31, 2018. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or significant changes in the forecasted hours, the reasons for the changes, along with the new estimates, will be communicated during the routine interactions with the assigned project manager.

These estimates are based on the NRC staff's initial review of the application and they could change, due to several factors including requests for additional information, unanticipated addition of scope to the review, and review by NRC advisory committees or hearing-related activities. Additional delay may occur if the submittal is provided to the NRC in advanc e or in parallel with industry program initiatives or pilot applications.

If you have any questions, please contact me.
