Acceptance Review for Peach Bottom - Relief Requests from ASME Section XI Code - 5th ISI interval Date:
Monday, May 07, 2018 10:53:00 AM
Dear Mr. Helker,
By letter dated April 19, 2018 (ADAMS Accession Nos. ML18109A116), Exelon Generation Company, LLC submitted five relief requests for Peach Bottom Atomic Power Station Units 2 and 3, that request relief from certain requirements related to reactor pressure vessel internals, containment, nozzles, and threads in flange that are included in the ASME Section XI Code, 2013 Edition.
The purpose of this e-mail is to provide the results of the Nuclear Regulatory Commission (NRC) staffs acceptance review of these relief requests. 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 for all five actions. The acceptance review is also intended to identify whether the relief requests have 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 requests for relief and concluded that they 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 relief requests 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 staffs 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 staffs detailed technical review by separate correspondence.
Based on the information provided in your submittal, the NRC staff has estimated that these relief requests will take a total of approximately 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> to complete. The NRC staff expects to complete this review by April 19, 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 staffs 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
