Enclosure to NL-22-0062 Editorial Corrections - Description, Corrections, and Assessment

Background

On December 13, 2021, pursuant to 10 CFR 50.90, Southern Nuclear Operating Company (SNC) requested a license amendment to Edwin I. Hatch Nuclear Plant (HNP) Unit 1 Renewed Facility Operating License DPR-57 and Unit 2 Renewed Facility Operating License NPF-5 (ADAMS Accession Number ML21347A385). The proposed amendment requested adoption of TSTF-227, Revision 0, involving clarification to the End of Cycle Recirculation Pump Trip (EOC-RPT) Instrumentation Technical Specifications (TS), and TSTF-297, Revision 1, involving enhancements to Feedwater and Main Turbine High Water Level Trip, EOC-RPT, and Anticipated Transient Without Scram (ATWS)-RPT TS.

Subsequent to the submittal, SNC identified the need to editorially correct certain non-technical aspects of the request. The table below identifies provides a description of each issue as well as corrections to the original request and an assessment of each correction. Each correction has been assessed to be of an editorial nature and none impact the technical or regulatory basis for the Technical Specifications changes requested in the original submittal, dated December 13, 2021. to this Enclosure provides the marked-up pages for HNP Units 1 and 2. provides revised (clean) TS pages. These pages have incorporated changes that address the editorial corrections described in the table below. Note that all HNP TS pages that were included in the original submittal are included in Attachments 1 and 2; this includes the pages corrected in this supplement as well as the pages that are unchanged by this supplement. All pages are included for clarity and convenience as this provides all marked-up and clean pages in a single submittal. Therefore, Attachments 1 and 2 of this Enclosure replace, in their entirety, Attachments 1 and 2, respectively, of the December 13, 2021, submittal.
