the definitions in the design certification rather than by the definitions in NEI 08-01, unless they seek an exemption from the Tier 1 definition. The NRC staff believes that the NEI 08-01 definitions could form the basis for a Tier 1 definition in future design certifications, design certification amendments, and plant-specific exemptions to already certified designs. Appendices to this Regulatory Guide Appendix A to this RG contains Enclosure 1 to SECY-10-0100, “Staff Progress in Resolving Issues Associated with Inspections, Tests, Analyses, and Acceptance Criteria,” dated August 5, 2010 (Ref. 7), which is a detailed discussion of when a license amendment is required in the ITAAC maintenance context. Although Sections 3.2, 8.1, and 8.2 of NEI 08-01 discuss the need for license amendments and exemptions in the ITAAC context, Appendix A to this RG is a more detailed discussion specifically focused on issues associated with ITAAC maintenance. Appendix B to this RG contains a flowchart and description for the implementation of 10 CFR 52.99 and 10 CFR 52.103(g) that the staff developed, as described in Enclosure 3 of SECY-08-0117, “Staff Approach To Verify Closure of Inspections, Tests, Analyses, and Acceptance Criteria and To Implement Title 10 CFR 52.99, ‘Inspection during Construction,’ and Related Portion of 10 CFR 52.103(g) on the Commission Finding,” dated August 7, 2008 (Ref. 8).
