Content:
spects of these items are included in the seismic and dynamic qualification testing. The specific areas of review are as follows: 1. Qualification Criteria. Qualification criteria are the criteria for qualification, such as the deciding factors for choosing between tests, analyses, or a combination of test and analysis, the considerations in defining the seismic and other relevant dynamic load input motions, and the demonstration of adequacy of the qualification program. 2. Structural Integrity and Functionality of Mechanical and Electrical Equipment. This area of review addresses the methods and procedures, including 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. This area of review addresses 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. 3.10-3 Draft Revision 4 – August 2015 4. Experience Database. If qualification by an experience-based approach is proposed, the staff reviews both the applicant’s justification to use an experience-based approach, and 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
