The bases for the exceptions to the guidelines should demonstrate that a significant reduction in the margin of safety does not result and that the exceptions do not result in nonconformance to the requirements of the acceptance criteria. 5. When the applicant/licensee proposes I&C systems that incorporate digital computers, the review includes the supplemental guidance for digital computer-based systems described in SRP Appendix 7.1-D. SRP Appendix 7.0-A describes the review process. 6. The review includes the I&C systems important to safety that are identified as identical to systems that have been reviewed and approved by the staff. The evaluation of these systems in subsequent sections of Chapter 7 is based on prior staff approval. When differences exist between prior approvals, the differences should be identified and the review should confirm that an adequate basis has been provided. The review should include an evaluation of the differences to confirm that they are acceptable. 7.1-9 Revision 5 - March 2007 7.

DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the
