ses are combined with the structural responses from other loads in accordance with the criteria in SRP Section 3.8. The criteria in SRP Section 3.7.2 ensure that the effects of the three components of earthquake motion and the effects of SSI are appropriately included in the evaluation. In addition, the use of these criteria allows the SSI analysis to calculate the floor response spectra for use in qualification of equipment. Meeting these requirements provides assurance that appropriate methods will be used to determine the structural response of systems, under the SSE and OBE (if applicable), which will ensure that they will remain functional within applicable acceptance limits. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant's evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in subsection II. 1. Seismic Analysis Methods. For all Category I SSCs, the applicable methods of seismic analysis (response spectra, time history and equivalent static load) are reviewed to
