The purpose of this letter is to provide a required report in accordance with 10 CFR 50.46, Acceptance Criteria for Emergency Core Cooling Systems for Light-Water Nuclear Power Reactors, for Turkey Point Units 6 and 7 (PTN 6 & 7). The PTN 6 & 7 CO Ls incorporate by reference AP1000 Design Certification Document (DCD) Revision 19, and thus also the peak fuel cladding temperature calculations performed by Westinghouse Electric Corporation (WEC). Accordingly, the referenced WEC 2018 Model Year 10 CFR 50.46 annual report for the AP1000 Design Certification analysis of record (AOR) applies to PTN 6 & 7. | The purpose of this letter is to provide a required report in accordance with 10 CFR 50.46, Acceptance Criteria for Emergency Core Cooling Systems for Light-Water Nuclear Power Reactors, for Turkey Point Units 6 and 7 (PTN 6 & 7).
