Content:
ding tests and analyses, used to ensure structural integrity and the functionality of mechanical and electrical equipment in the event of a safe-shutdown earthquake (SSE), after a number of postulated occurrences of the operating-basis earthquake (OBE), and in combination with other relevant dynamic and static loads. 3. Supports. The methods and procedures of analysis or testing of the supports for mechanical and electrical equipment and the procedures used to account for possible amplification of vibratory motion (amplitude and frequency content) under seismic and dynamic conditions. 4. Experience Database. If qualification by an experience-based approach is proposed, the staff reviews and approves the details of the experience database, including applicable implementation procedures, to ensure structural integrity and functionality of the in- scope mechanical and electrical equipment. Supporting documentation for equipment identified in the database should confirm that such equipment would remain functional during and after an SSE in addition to the equivalent effect of five postulated occurrences of OBE in combination with other relevant static and dynamic loads. 5. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." 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. 6. COL Action Items and Certification Requirements and Restrictions. For a DC
