Content:
Section 3.7.1. The combination of earthquake- resultant loads with those resulting from normal and accident conditions in the design of Category I structures as specified in SRP Sections 3.8.1 through 3.8.5 will be in conformance with item 2 listed above. The scope of review of the seismic system and subsystem analysis for the plant included the seismic analysis methods for all Category I SSCs. It included review of procedures for modeling, seismic SSI, development of floor response spectra, inclusion of torsional effects, seismic analysis of Category I concrete dams, evaluation of Category I structure overturning, and determination of composite damping. The review included design criteria and procedures for evaluation of the interaction of non-Category I structures with Category I structures and the effects of parameter variations on floor response spectra. The review also included criteria and seismic analysis procedures for Category I buried piping outside containment and above-ground Category I tanks.
