REVIEW RESPONSIBILITIES Primary - The organization responsible for reviews of seismic/geotechnical issues Secondary - None I. AREAS OF REVIEW The specific areas of review are as follows: 1. Comparison with guidance provided in Regulatory Guide 1.12. A comparison is made of the proposed seismic instrumentation with the seismic instrumentation guidelines of Regulatory Guide (RG) 1.12. In addition, the bases for elements of the program that differ from RG 1.12 are reviewed. The locations for the installation of seismic instrumentation that will be installed in selected Category I structures and components are reviewed. Also reviewed are the bases for selection of the instrumentation and locations and a discussion of the extent to which the seismic instrumentation will be maintained to enable a rapid determination of the severity of the earthquake. 2. Comparison with RG 1.166. A comparison is made of (1) the proposed procedures for a timely evaluation after an earthquake of the recorded seismic instrumentation data and (2) for determining whether plant shutdown is required with the post-earthquake guidelines of RG 1.166. Also reviewed are the criteria for evaluation of the ground motion records and for determining the exceedance of the Operating Basis Earthquake (OBE) ground motion. 3.7.4-2 Revision 2 - March 2007 3. 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
