Subject:
Information Submittal Related to the AP1000 Design Certification Extension By letter dated June 26, 2020 (reference 1), Westinghouse Electric Company LLC (Westinghouse) requested the U.S. Nuclear Regulatory Commission (NRC) extend the duration of the AP1000 design certification (DC). SECY-20-0082 (reference 2) recommended to extend the AP1000 DC an additional five years beyond the current expiration date of February 27, 2021 using the direct final rule process. Staff Requirements Memorandum - SECY-20-0082 (reference 3) approved the recommendation.
In order to enable the NRC staff to make the necessary safety findings under 10 CFR 52.54, Westinghouse hereby submits information that documents five previously resolved technical issues related to the AP1000 design certification. These technical issues were resolved as part of the Levy Nuclear Plant Units 1 & 2, William States Lee III Nuclear Station Units 1 & 2, and Turkey Point Units 6 & 7 AP1000 combined license (COL) applications, as well as the Vogtle Electric Generating Plant Units 3 & 4 COL. The purpose of this submittal is to provide the information necessary to update the generic certified design with the same information that NRC previously reviewed and approved.
This letter does not constitute a DC renewal application request per 10 CFR 52.57. Westinghouse is available to discuss if further clarification is needed. Questions can be directed to Zachary Harper at 412-374-5093 or harperzs@westinghouse.com.
