Acceptance Review for Peach Bottom - Relief Request from ASME Section XI Code - 4th ISI interval I4R-63 (EPIDS L-2018-LLR-0133)

Dear Mr. Helker,

By letter dated October 16, 2018 (ADAMS Accession Nos.

ML18289A473

), Exelon Generation Company, LLC submitted a relief request for Peach Bottom Atomic Power Station Units 2 and 3, that requests relief from certain requirements related the examination of the Standby Liquid Control (SLC) nozzle inside radius section that is included in the ASME Section XI Code, 2001 Edition and 2003 Addenda.

The purpose of this e-mail is to provide the results of the Nuclear Regulatory Commission (NRC) staff's 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 relief request has any readily apparent information insufficiencies in the characterization of the regulatory requirements or the licensing basis of the plant.

The NRC staff has reviewed your request for relief and concluded that it provides 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 this relief request in terms of 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 technical review are identified despite completion of an adequate acceptance review.

You will be advised of any further information needed to support the NRC staff's detailed technical review by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated that this relief request will take a total of approximately 130 hours0.0015 days <br />0.0361 hours <br />2.149471e-4 weeks <br />4.9465e-5 months <br /> to complete. The NRC staff expects to complete this review by October 16, 2019, as you requested.

If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date (greater than a month) or significant changes in the forecasted hours (greater than 25%), 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 advance or in parallel with industry program initiatives or pilot applications.

Please contact me if you have any questions. A copy of this email will be made publicly available in ADAMS.

Thanks,-Jenny
