REGARDING A PROPOSED LICENSE AMENDMENT REQUEST TO ADOPT TSTF-505 FOR EDWIN I. HATCH NUCLEAR PLANT, UNITS 1 AND 2 (EPID NO. L-2021-LRM-0072)

On September 7, 2021, an Observation Public Meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Southern Nuclear Operating Company, Inc. (SNC, the licensee). This follow-up pre-licensing meeting was for SNC to describe its plan to submit a license amendment request (LAR) to adopt Technical Specification Task Force (TSTF)-505-A, Revision 2, Provide Risk-Informed Extended Completion Times - RITSTF Initiative 4b, July 2, 2018 (Agencywide Do cuments Access and Management System (ADAMS)

Accession Package No. ML17290A003), for Edwin I. Hatch Nuclear Plant (Hatch), Units 1 and

2. This is a follow-up, pre-licensing meeting to the meeting held on August 16, 2021, regarding the same topic.

A list of attendees is provided as an Enclosure.

On August 30, 2021 (ADAMS Accession No. ML21242A497), the meeting was noticed on the NRC public webpage.

The NRC staff opened the meeting with introductory remarks and introduction of the attendees.

SNC representatives said that the proposed LAR is based on TSTF-505, Revision 2, and Nuclear Energy Institute (NEI) 06-09, Revision 0-A, Risk Informed Technical Specifications Initiative 4b: Risk Managed Technical Specifications (RMTS), October 22, 2012 (ADAMS Accession No. ML122860402). The licensee stated that risk-informed completion times (RICTs) apply in MODE 1 only, consistent with the Pr obabilistic Risk Assessment (PRA) model, and only PRA-modeled features or appropriate surrogates have RICT proposed. SNC said that no Loss of Function RICTs are proposed.

The SNC representatives discussed the following topics: (1) introduction, and (2) LAR overview.

SNC presented the slides contained in ADAMS Accession No. ML21222A034. SNC skipped over the PRA models and configuration risk model overview.

The NRC staff asked questions and provided su ggestions regarding the following topics:

(1) required NOTE for potential loss of function TS conditions, (2) 1B swing emergency diesel generator (EDG) alignment configuration and manual actions for loss-of-offsite power (LOOP) and LOOP/ loss-of-coolant accident (LOCA), (3) potential loss of function for RICTs with postulated conditions: LOOP, LOCA, and LOOP and LOCA, (4) risk management action (RMA) examples for TS 3.8, (5) defense-in-depth (DID) analysis, and (6) design success criteria in Table E.1-1 of the LAR should not defeat the TS conditions action statement.

Public Questions to NRC

There were no members of the public in attendance.

Closing

The NRC staff made no regulatory decisions during the meeting.

Once received, the NRC staff will perform a thorough review of the proposed LAR and make any regulatory decisions in writing in a time ly manner. Public Meeting Feedback forms were available, but no comments were received. The meeting adjourned at 10:47 am (Eastern time).
