eriodically, as appropriate, to accommodate comments and to reflect new Informa- tion and experience. Comments and suggestions for improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission, Office of Nuclear Reactor Regulation, Washington. D.C. 205 5. Analysis Procedure for Damping The information reviewed is similar to that described in subsection 1.13 of SRP Section 3.7.2 but as applied to Category I subsystems. 6. Three Components of Earthquake Motion The information reviewed is similar to that described in subsection I.6 of SRP Section 3.7.2 but as applied to Category I subsystems. 7. Combination of Model Responses The information reviewed is similar to that described in subsection I.7 of SRP Section 3.7.2 but as applied to Category I subsystems. 8. Interaction of Other Systems With Category I Systems The seismic analysis procedures to account for the seismic motion of non- Category I systems in the seismic design of Category I systems are reviewed. 9. Multiply-Supported Equipment and Components with Distinct Inputs The criteria and procedures for seismic analysis of equipment and compo- nents supported at different elevations within a building and between buildings with distinct inputs are reviewed. 10. Use of Equivalent Vertical Static Factors The information reviewed is similar to that described in subsection 1.10 of SRP Section 3.7.2 but as applied to Category I subsystems. 11. Torsional Effects of Eccentric Masses The criteria and procedures that are used to consider the torsional effects of eccentric masses in seismic subsystem analyses are reviewed. 12. Category I Buried Piping. Conduits, and Tunnels For Category I buried piping, conduits, tunnels, and auxiliary systems, the seismic criteria and methods which consider the compliance characteristics of soil media, dynamic pressures, settlement due to earthquake and differ- ential movements at support points, penetrations, and entry points into structures provided with
