"License Amendment Request to Implement a Digital Upgrade to the Core Protection Calculator (CPC) system and Control Element Assembly Calculator (CEAC) system," (ADAMS Accession No. ML20205L588), dated July 23, 2020.

In the Referenced letter, Entergy Operations, Inc. (Entergy) submitted a proposed amendment to Appendix A, "Technical Specifications" (TS) of Renewed Facility Operating License No.

NPF-38 for Waterford Steam Electric Station, Unit 3 (Waterford). The proposed change would revise the Waterford TS in order to implement a planned digital instrumentation and control (DI&C) modification at Waterford. The DI&C modification will replace the existing digital minicomputers of the Core Protection Calculator (CPC) system and Control Element Assembly Calculator (CEAC) system with the more reliable, digital system based on the Westinghouse Electric Company (Westinghouse) Common Qualified (Common QTM) Platform.

The referenced license amendment request (LAR) included a List of Regulatory Commitments in Attachment 15, which contained a single commitment. The purpose of this letter is to resubmit the commitment to reference WCAP-16096, Software Program Manual for Common QTM Systems, instead of WCAP-16097, Common Qualified Platform Topical Report. The Enclosure to this letter provides the revised List of Regulatory Commitments.

The No Significant Hazards Consideration determination provided in the referenced submittal is not altered by the information provided in this letter.
