R.E. Ginna NPS - ACCEPTANCE REVIEW: To Revise Technical Specifications for Steam Generator tube inspection frequency (L-2020-LLA-0207)

By letter dated September 21, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20265A198) Exelon Generation Company, LLC, submitted the License Amendment Request (LAR) to revise Technical Specifications for Steam Generator tube inspection frequency for R.E. Ginna Nuclear Power Station (Ginna). Specifically, the licensee requested to revise Technical Specifications (TS) 5.5.8, Steam Generator (SG) Program, to reflect a proposed change to the required SG tube inspection frequency. This request is for a one-time change to modify the SG inspection frequency from the current wording No steam generator shall operate more than 72 effective full power months or three refueling outages (whichever is less) without being inspected to add the phrase with the exception that each steam generator is to be inspected during the fourth refueling outage, in G1R44, following inspections that were completed in refueling outage G1R40.

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.

The NRC staff has reviewed your relief request 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 license amendment 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. 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 review of this request will take approximately 260 hours0.00301 days <br />0.0722 hours <br />4.298942e-4 weeks <br />9.893e-5 months <br /> for this amendment to complete. The NRC staff expects to complete this review in approximately 9 months from acceptance (July 2021). 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 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.
