uesting document displays a currently valid OMB control number. 2.5.2-23 Draft Revision 5 – 2013 SRP Section 2.5.2 Description of Changes Section 2.5.2 “VIBRATORY GROUND MOTION” This SRP section affirms the technical accuracy and adequacy of the guidance previously provided in Revision 4, dated March 2007 of this SRP. See ADAMS Accession No. ML070730593. Changes include considerations in areas related to determination of site- specific vibratory ground motion based on lessons learned from past Section 2.5.2 reviews. Each section of the SRP has text that was updated for editorial and clarifying purposes. The technical changes incorporated in Revision 5 are as below: I. AREAS OF REVIEW 1. Clarified the definition and use of the ground motion response spectra (GMRS). 2. Deleted reference to Regulatory Guide 1.165, which was withdrawn in March 2010 (see 75 FR 22868). II. ACCEPTANCE CRITERIA 1. Clarified the use of high frequency spectra for plants located in the CEUS due to lessons learned during past reviews. 2. Deleted reference to Regulatory Guide 1.165, which was withdrawn in March 2010 (see 75 FR 22868). 3. Inserted Regulatory Guides 1.138 and 1.198 due to lessons learned during past reviews. 4. Incorporated Interim Staff Guidance document ISG-017. 5. Removed reference to the outdated probabilistic seismic hazard analysis (PSHA) studies of Lawrence Livermore National Laboratory (LLNL) and Electric Power Research Institute (EPRI). 6. Incorporated reference to NUREG-2115. 7. Incorporated reference to NUREG-2117. 8. Updated guidance on the use of the cumulative absolute velocity (CAV) filter in accordance with SECY-12-0025. 9. Clarified the use of vertical and horizontal (V/H) spectral ratios for proposed structures with deep site elevations. 2.5.2-24 Draft Revision 5 – 2013 III. REVIEW PROCEDURES 1. Insert reference to design certification (DC) applications. 2. Clarified link between the GMRS and the safe shutdown earthquake (SSE) spectra. IV. EVALUATION
