r guidance. 3.2.1-3 Draft Revision 3 – August 2015 the damage, in accordance with 10 CFR Part 50, Appendix S. A list of the SSCs necessary for continued safe operation during and following an OBE is not required at the design stage. However, a list of SSCs necessary for continued safe operation during and following an OBE is needed to support plant inspections for damage after an earthquake; timing for providing the list should be determined by NUREG-0800 Standard Review Plan (SRP) Chapter 13 reviewers or those responsible for pre-earthquake planning and post-earthquake inspection procedures. b. Certain equipment that is only designed to withstand the OBE is addressed by specific regulatory guidance, such as RG 1.143. 5. Where portions of structures and fluid systems are seismic Category I, they also need to be clearly identified. For fluid systems important to safety, the classification tables in the SAR should identify system components such as pressure vessels, heat exchangers, storage tanks, pumps, piping, and valves, have suitable footnotes defining interfaces, and be in sufficient detail so that there is a clear understanding of the extent of those portions of the system that are classified as seismic Category I. 6. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For DC and COL reviews, the staff reviews the applicant’s proposed ITAAC associated with the SSCs related to this SRP section in accordance with SRP Section 14.3. The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of review are identified and addressed as appropriate in accordance with SRP Section 14.3. 7. COL Action Items and Certification Requirements and Restrictions. For a DC application, the review will also address COL action items and requirements and
