These eleven commitments had various dates for completion. In addition, in an October 5, 2006 letter, Duke committed to responding to the GL 2004-02 Request for Additional Information (RAIs) from the February 9, 2006 NRC letter within 90 days of the completion of the McGuire Unit 1 outage, not to exceed December 31, 2007. In a letter dated January 4, 2007 from the NRC to all licensees, the NRC stated that the agency expects all PWR licensees to submit supplemental responses as soon in 2007 as the information and analyses results are available; all-responses to be submitted no later than December 31, 2007. Finally, in a joint industry and NRC meeting on April 18, 2007, the NRC provided, for review and comment, a draft content guide for GL 2004-02 supplemental responses. As a result, Duke amends the commitments in the previous correspondence (June 28, 2006 and October 5, 2006) to the following:
