Revision 2 – December 2011 emphasize the importance of maintaining a current licensing basis (CLB) and a discussion on CLB is provided for information following this section. These efforts have involved issues related to loss of configuration control, design-basis reconstitution, commitment management and commitment change control. The staff has identified two approaches for providing the information necessary to maintain the design-basis for the facility: 1) include specific design-basis information items in a license condition, and 2) include design-basis information in FSAR updates required by 10 CFR 50.71(e). In the first approach, the focus is on ensuring that FSAR information that is identified during the COL review process and is necessary to include in the design-basis is included in an FSAR update. In the second approach, the focus is on ensuring that routine FSAR updates that have traditionally occurred following issuance of an OL are performed. These routine FSAR updates are typically associated with: • Changes to the facility in accordance with the requirements of 10 CFR 50.59 • Changes to the facility resulting from approved exemptions and departures from a referenced certified design • Changes to the facility resulting from approved variances from a referenced ESP • Amendments to the license in accordance with the requirements of 10 CFR 50.90 The two approaches for FSAR information commitments are discussed below: FSAR information commitment included in a license condition The regulations in 10 CFR 50.71(e) and the appendices to 10 CFR Part 52 that contain the DCRs include requirements for holders of COLs to update their FSARs. Specifically, 10 CFR 50.71(e)(3)(iii) requires that an update of the FSAR be submitted annually to the NRC during the period from the docketing of a COL application until the Commission makes the finding under 10 CFR 52.103(g). In addition, 10 CFR 50.71(e)(4) requires that subsequent FSAR revisions be filed annually or
