nd accelerations) is reviewed, including that for modes with closely spaced frequencies. F. Analytical Procedures for Piping Systems. The analytical procedures applicable to seismic analysis of piping systems, including methods used to consider differential piping support movements at different support points located within a structure and between structures, are reviewed. G. Multiply-supported Equipment and Components with Distinct Inputs. The criteria and procedures for seismic analysis of equipment and components supported at different elevations within a building and between buildings with distinct inputs are reviewed. H. Use of Constant Vertical Static Factors. Where applicable, the justification provided for using constant static factors rather than a vertical seismic system dynamic analysis to compute vertical response loads for design of affected systems, components, equipment and their supports is reviewed. I. Torsional Effects of Eccentric Masses. The criteria and procedures that are used to consider the torsional effects of eccentric masses (e.g., valve operators) in seismic system analyses are reviewed. J. Category I Buried Piping Systems. For Category I buried piping, the seismic criteria and methods which consider the effect of fill settlement, including pipe profile and pipe stresses, the movements at support points, penetrations, and anchors, are reviewed. 3.9.2-4 Revision 3 - March 2007 K. Interaction of Other Piping With Category I Piping. The seismic analysis procedures to account for the seismic motion of non-Category I piping systems in the seismic design of Category I piping are reviewed. L. Criteria Used for Damping. The criteria to account for damping in systems, components, equipment and their supports is reviewed. 3. Dynamic responses of structural components within the reactor vessel caused by steady-state and operational flow transient conditions should be analyzed for prototype (first of a design) reactors. Generally, this analysis is
