Subject:
Supplemental Information Supporting the Request for Exemption from Certain Requirements in 10 CFR 50.55a(h)(2) using Risk-Informed Process for Evaluations
Ladies and Gentlemen:
By letter dated February 6, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24037A284), as supplemented by letter dated April 3, 2024 (ADAMS Accession No. ML24094A105), Duke Energy Progress, LLC (Duke Energy) submitted a request under the Risk-Informed Process for Ev aluations (RIPE) for an exemption from the requirements of 10 CFR 50.55a(h)(2), Protection systems, requiring protection systems meet the requirements of IEEE 279-1971, Criteria for Protection Systems for Nuclear Power Generating Stations, for the Shearon Harris Nuclear Power Plant, Unit 1 (HNP). Specifically, the exemption request would no longer require the Reactor Protection System (RPS) cables that terminate within the Turbine Control System (TCS) Cabinet G (1TCS-CAB-G) to meet IEEE 279-1971 Section 4.6, Channel Independence, for independence and physical separation.
A call was conducted on May 22, 2024 between Duke Energy and Nuclear Regulatory Commission (NRC) staff to discuss information made available on an online reference portal per the audit plan submitted to the site by electronic mail on April 22, 2024 (ADAMS Accession No. ML24113A252). The NRC staff requested that additional information related to the impact a fault on the subject cables would have on the non-safety-related turbine trip on reactor trip function be submitted on the docket to support the development of the NRC staffs safety evaluation.
The enclosure to this letter provides the requested supplemental information to the application.
There are no new regulatory commitments contained within this letter.
Please refer any questions regarding this submittal to Ryan Treadway, Director - Nuclear Fleet Licensing, at 980-373-5873.

INTRODUCTION
By letter dated February 6, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24037A284), as supplemented by letter dated April 3, 2024 (ADAMS Accession No. ML24094A105), Duke Energy Progress, LLC (Duke Energy) submitted a request under the Risk-Informed Process for Ev aluations (RIPE) for an exemption from the requirements of 10 CFR 50.55a(h)(2), Protection systems, requiring protection systems meet the requirements of IEEE 279-1971, Criteria for Protection Systems for Nuclear Power Generating Stations, for the Shearon Harris Nuclear Power Plant, Unit 1 (HNP). Specifically, the exemption request would no longer require the Reactor Protection System (RPS) cables that terminate within the Turbine Control System (TCS) Cabinet G (1TCS-CAB-G) to meet IEEE 279-1971 Section 4.6, Channel Independence, for independence and physical separation.
A call was conducted on May 22, 2024 between Duke Energy and Nuclear Regulatory Commission (NRC) staff to discuss information made available on an online reference portal per the audit plan submitted to the site by electronic mail on April 22, 2024 (ADAMS Accession No. ML24113A252). The NRC staff requested that additional information related to the impact a fault on the subject cables would have on the non-safety-related turbine trip on reactor trip function be submitted on the docket to support the development of the NRC staffs safety evaluation.
SUPPLEMENTAL INFORMATION
A fault (e.g., short circuit, hot short, electrical anomaly, fire) on the Turbine Trip System (TTS) cables that interface with Solid State Protection System (SSPS) relay output contacts and the reactor trip switchgear breaker output contacts does not have an adverse impact on the ability of SSPS to trip the reactor. A fault of the TTS cables could impact the non-safety related automatic turbine trip on reactor trip function. For example, a fault could cause a short circuit which could bypass the SSPS turbine trip output relay contacts, thus preventing the turbine from tripping. If this were to occur and a reactor trip occurred, Operations would trip the turbine manually by the Main Control Board turbine trip switch per step 2 of HNP Emergency Operating Procedure EOP-E-0, REACTOR TRIP OR SAFETY INJECTION.
