Subject:
Supplement to the License Amendment Request for Temporary Changes to Technical Specifications for the 'A' Emergency Service Water Pump Replacement Ladies and Gentlemen:
By letter dated October 29, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML15302A542), Duke Energy Progress, Inc. (Duke Energy), requested a license amendment for the Technical Specifications (TS) for the Shearon Harris Nuclear Power Plant, Unit 1 (HNP) to allow temporary changes to TS 3.1.2.4, Charging Pumps -
Operating, TS 3.5.2, ECCS [Emergency Core Cooling Systems] Subsystems - Tavg Greater Than or Equal To 350°F, TS 3.6.2.1, Containment Spray System, TS 3.6.2.2, Spray Additive System, TS 3.6.2.3, Containment Cooling System, TS 3.7.1.2, Auxiliary Feedwater System, TS 3.7.3, Component Cooling Water System, TS 3.7.4, Emergency Service Water System, TS 3.7.6, Control Room Emergency Filtration System, TS 3.7.7, Reactor Auxiliary Building (RAB) Emergency Exhaust System, TS 3.7.13, Essential Services Chilled Water System, and TS 3.8.1.1, AC [Alternating Current] Sources - Operating. The proposed license amendment requested will permit the 'A' Emergency Service Water (ESW) pump to be inoperable for 14 days to allow for the replacement of the A Train ESW pump with design upgrades to improve reliability.
The NRC staff reviewed the request and determined that additional information was needed to complete their review. Duke Energy has supplemented its application per letters dated February 16, 2016 (ADAMS Accession No. ML16047A389), August 8, 2016 (ADAMS Accession No. ML16221A711) and August 26, 2016 (ADAMS Accession No. ML16239A306).
On September 7, 2016, the NRC staff identified inconsistencies in the proposed TS changes and the revised TS pages. By this letter, Duke Energy provides updated proposed TS changes and revised TS pages that address these inconsistencies. Attachment 1 provides a summary of the changes included in this supplement. Attachment 2 provides a copy of the proposed TS changes. Attachment 3 provides a copy of the revised TS pages.
U.S. Nuclear Regulatory Commission Page 2 of 2 Serial HNP-16-072 In accordance with 10 CFR 50.91(b), HNP is providing the state of North Carolina with a copy of this response.
This letter contains no new Regulatory Commitments.

U.S. Nuclear Regulatory Commission Page 1 of 1 Serial HNP-16-072 By letter dated October 29, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML15302A542), Duke Energy Progress, Inc. (Duke Energy), requested a license amendment for the Technical Specifications (TS) for the Shearon Harris Nuclear Power Plant, Unit 1 (HNP) to allow temporary changes to TS 3.1.2.4, Charging Pumps -

The NRC staff reviewed the request and determined that additional information was needed to complete their review. Duke Energy has supplemented its application per letters dated February 16, 2016 (ADAMS Accession No. ML16047A389), August 8, 2016 (ADAMS Accession No. ML16221A711) and August 26, 2016 (ADAMS Accession No. ML16239A306).
On September 7, 2016, the NRC staff identified two administrative issues in the proposed TS changes and the revised TS pages provided per Duke Energy letter dated August 26, 2016.
In TS 3.6.2.1, the changes to the surveillance requirement associated with License Amendment (LA) 150 issued on April 29, 2016, were not incorporated in the TS markup or in the retyped TS pages. Additionally, since the changes associated with LA 150 include a note with an asterisk, the note being added with this proposed amendment has been modified to include a double asterisk for clarity.
In TS 3.7.3, the note at the bottom of the page contained the designation of the pumps as IC-SAB, IA-SA, and IB-SB in both the TS markup and the retyped TS pages, which are not the designations shown in NRC-approved TS. The designation of the pumps should be 1C-SAB, 1A-SA, and 1B-SB.
These issues have been corrected in the updated proposed TS changes and revised TS pages within Attachment 2 and Attachment 3 of this submittal, respectively. There are no changes to the information provided in the significant hazards consideration within the license amendment request (LAR) submitted on October 29, 2015. As such, the conclusion of the original significant hazards consideration remains applicable.
