Florida Power & Light Company (FPL), acting on behalf of itself and as agent for NextEra Energy Point Beach, LLC, is revising the implementation schedule for the open phase condition for St. Lucie Units 1 & 2, Turkey Point Units 3 & 4, and Point Beach Units 1 & 2. In 2016, these plants committed to the Nuclear Energy Institute (NEI) Industry Initiative on Open Phase Condition, Revision 1, dated March 2015, or any subsequent revision issued by NEI. In Reference 1, NEI submitted revision 2 of the Industry Initiative on Open Phase, which included a revised implementation schedule. Although FPL withdrew its membership from NEI in February 2018; as qiscussed in Reference 2, the withdrawal did not impact prior commitments to NEI documents or cominitments made by NEI on behalf of FPL. Therefore, consistent with the current commitments, FPL will adhere to the implementation schedule for the Industry Initiative on Open Phase Condition, Revision 2.

References 3, 4, and 5 provided a summary of the interim corrective actions taken at Point Beach, St.

Lucie, and Turkey Point to ensure plant operators can promptly diagnose and respond to an open phase condition. However, consistent with Reference 1, these plants will implement design changes in a monitoring mode with procedures that direct the response actions if the system detects the presence of an open phase condition. These actions supersede the interim corrective actions. }£> /))/fl
