dominant frequencies of the support structure. Use of equipment frequencies within this range is acceptable if the equipment is adequately designed for the applicable loads. 5. Analysis Procedure for Damping. The acceptance criteria provided in SRP Section 3.7.2, subsection II.13, are applicable. 6. Three Components of Earthquake Motion. The acceptance criteria provided in SRP Section 3.7.2, subsection II.6, are applicable. 7. Combination of Modal Responses. The acceptance criteria provided in SRP Section 3.7.2, subsection II.7, are applicable. 8. Interaction of Other Systems With Seismic Category I Systems. To be acceptable, each non-seismic Category I system should be designed to be isolated from any seismic Category I system by either a constraint or barrier, or should be remotely located with regard to the seismic Category I system. If this is not feasible or practical, then adjacent non-seismic Category I systems should be analyzed according to the same seismic criteria as applicable to the seismic Category I system. For non-seismic Category I systems attached to seismic Category I systems, the dynamic effects of the non-seismic Category I systems should be simulated in the modeling of the seismic Category I system. The attached non-seismic Category I systems, up to the first anchor beyond the
