Limerick Units 1 and 2: Acceptance Review: Relief Request No. I4R-17, Revision 1, to request relief an alternative to the requirements in the ASME Code, Section XI (CAC No. 000976; EPID No. L-2018-LLR-0071)

Date: Monday, June 04, 2018 5:00:00 PM By letter dated May 4, 2018 (ADAMS Accession No. ML18129A331), Exelon Generation Company, LLC (Exelon, the licensee) requested relief from the requirements of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code), Section XI, 2007 Edition with 2008 Addenda at Limerick Generating Station, Unit 2.

Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(z)(2), Exelon submitted Relief Request No. I4R-17, Revision 1, associated with Reactor Pressure Vessel Nozzle Repairs. This request is on the basis that compliance with the ASME Code, Section XI requirements would result in hardship or unusual difficulty without a compensating increase in the level of quality of safety. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the 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 assessment regarding the acceptability of the proposed amendment 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.

Based on the information provided in your submittal, the NRC staff has estimated that this request will take approximately 200 hours8.333 days <br />1.19 weeks <br />0.274 months <br /> to complete. The NRC staff expects to complete this review in approximately 11 months, which is April 14, 2019. 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 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.

If you have any questions, please contact me at (301) 415-2597.
