SHEARON HARRIS NUCLEAR POWER PLANT, UNIT 1- ACCEPTANCE OF RISK-INFORMED LICENSE AMENDMENT REQUEST FOR EXTENSION OF THE ESSENTIAL SERVICES CHILLED WATER SYSTEM ALLOWED OUTAGE TIME AND REMOVAL OF AN EXPIRED NOTE FROM TECHNICAL SPECIFICATIONS (EPID L-2019-LLA-0025)

Ms. Hamilton, By letter dated February 18, 2019 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML19049A027), Duke Energy Progress, LLC (Duke Energy) submitted a risk-informed license amendment request (LAR) for Shearon Harris Nuclear Power Plant, Unit 1. The proposed amendment would modify Technical Specifications (TSs) requirements to allow one train of the Essential Services Chilled Water System (ESCWS) to be inoperable for up to 7 days from the currently allowed 72 hours3 days <br />0.429 weeks <br />0.0986 months <br /> for extended maintenance activities on the ESCWS and air handlers supported by the ESCWS for equipment reliability. The LAR would also remove an expired Note in numerous TS sections that was previously added by implementation of license amendment 153.

The purpose of this e-mail is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this license amendment 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 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 independent 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 license amendment request will take approximately 942 hours39.25 days <br />5.607 weeks <br />1.29 months <br /> to complete. The NRC staff expects to complete this review in March 2020. 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, and unanticipated addition of scope to the 1

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 Martha.Barillas@nrc.gov or at (301) 415-2760.
