On March 30, 2012, the Commission issued Memorandum and Order CLI-12-09 (Ref. 16), which included the requirements for mitigation strategies as a license condition for Virgil C. Summer Nuclear Station, Units 2 and 3. These requirements were subsequently included as license condition 2.D.(13) on both combined license NPF-93 and combined license NPF-94 for those units. On May 4, 2012, NEI submitted NEI 12-06, Rev. B (Ref. 17), to provide specifications for an industry developed method for the development, implementation, and maintenance of guidance and strategies in response to the Mitigating Strategies Order. On May 13, 2012, NEI submitted NEI 12-06, Rev. B1 (Ref. 18).
