On February 24, 2022, the NRC Commission issued two orders (CLI-22-02 and CLI-22-03) and Staff Requirements Memorandum, SECY-21-0066, "Rulemaking Plan for Renewing Nuclear Power Plant Operating Licenses – Environmental Review," that impact the subsequent license renewal of Peach Bottom Atomic Power Station, Units 2 and 3, among others. 

The subsequent renewed licenses for Peach Bottom are still in place. The Commission ordered that the expiration date of the subsequently renewed licenses be reset to the end of the initial period of extended operation (as affirmed in orders CLI-22-06 and CLI-22-07). The Commission's direction will hold until the staff completes its re-evaluation of generic environmental issues for subsequent license renewal.

On June 5, 2024, the licensee submitted a letter to the NRC regarding the subsequent license renewal of Peach Bottom in which the licensee requested that the NRC provide a plan for completing the environmental review for Peach Bottom and for restoring the end dates for the subsequent renewed licenses (ML24157A069). By letter dated September 6, 2024 (ML24221A258), the NRC provided a plan for completing the required regulatory activities to include an environmental audit. By letter dated November 13, 2024 (ML24313A101) the NRC provided a detailed environmental audit plan. The environmental audit has concluded, and the NRC provided a summary of the audit activities and requests for additional information and requests for confirmation of information in a letter dated December 13, 2024 (ML24344A110). By letter dated February 28, 2025 (ML25035A001), the NRC estimated 2,650 hours for the supplemental environmental review and a licensing decision date of March 2026.

On April 24, 2025, the NRC issued a revised schedule and estimate to complete the supplemental environmental review and restore the end dates for the subsequent renewed licenses (ML25108A128). NRC reduced the supplemental environmental review estimate from 2,650 hours to 1,450 hours as a result of continued refinement and application of process improvement initiatives, contributing to the revised total estimate of 22,908 hours. The licensing decision date was modified from March 2026 to February 2026, as indicated in the schedule below.
