NL-22-0757 Assessment of Amendments 317 and 262 Impact on HNP TSTF-505 License Amendment Request

1.0 INTRODUCTION

On October 26, 2021 [ADAMS Accession Number ML21300A153], Southern Nuclear Operating Company (SNC) requested amendments to Edwin I. Hatch Nuclear Plant (HNP), Units 1 and 2 renewed facility operating licenses (RFOLs) DPR-57 and NPF-5, respectively. The proposed amendment requested U.S. Nuclear Regulatory Commission (NRC) approval to modify Technical Specifications (TS) requirements to permit the use of Risk Informed Completion Times in accordance with TSTF-505, Revision 2, "Provide Risk-Informed Extended Completion Times - RITSTF Initiative 4b" [ML18183A493]. The LAR impacted several TS sections, including TS 3.6.1.3, Primary Containment Isolation Valves.

On December 6, 2021, subsequent to the submittal of the HNP TSTF-505 license amendment request (LAR), SNC submitted a LAR to adopt certain aspects of TSTF-207 [ML21340A255].

On September 2, 2022, the NRC issued Amendments 317 and 262 to the HNP Units 1 and 2 RFOLs, respectively, approving SNCs HNP TSTF-207 LAR. Amendments 317 and 262 include changes to some of the same pages in TS 3.6.1.3 as SNCs TSTF-505 LAR.

2.0 DESCRIPTION

OF CHANGE AND ASSESSMENT OF IMPACT The issuance of HNP RFOL Amendments 317 and 262 included issuance of revised TS pages 3.6-7 through 3.6-12 (impacts TS 3.6.1.3 Conditions A through D and Required Action D.1 Completion Time). The Hatch TSTF-505 LAR included changes to TS pages 3.6-7 through 3.6-9 (impacts Condition A Required Actions and Completion Times and Required Action Completion Time C.2), thus there is overlap in the affected pages. Table 1 provides descriptions of the changes and assess the impact Amendments 317 and 262 have on SNCs HNP TSTF-505 LAR.
