Acceptance Review - Limerick 1 and 2 - Relief Request GVRR-8 (CAC Nos.

MF8787 and MF8788)

Stephanie, By letter dated November 3, 2016 (ADAMS Accession No. ML16308A329), Exelon Generation Company, LLC (Exelon) submitted relief request GVRR-8 associated with the third 10-year inservice testing interval for Limerick Generating Station (LGS), Units 1 and 2.

The purpose of this e-mail is to provide the results of the NRC staffs acceptance review of relief request GVRR-8. 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.

Pursuant to Sections 50.55a(z)(1) and 50.55a(z)(2) of Title 10 of the Code of Federal Regulations (10 CFR), the applicant shall demonstrate that the proposed alternatives would provide an acceptable level of quality and safety, or that compliance with the specified requirements of Section 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality or safety.

The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the staff to proceed with 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. 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 this request will take approximately 80 hours3.333 days <br />0.476 weeks <br />0.11 months <br /> to complete. The NRC staff expects to complete this review in approximately 5 months, which is April 3, 2017, as requested by Exelon in order to support the LGS Unit 2 spring 2017 refueling outage. 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 our routine interactions.

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 and unanticipated addition of scope to the review. Additional delay may occur if the submittal is provided to the NRC in advance or in parallel with industry program initiatives or pilot applications.

If you have any questions, please contact me at (301) 415-1420.
