8 Rev. 2 - August 1989 6. Three Components of Earthquake Motion The procedures by which the three components of earthquake motion are con- sidered in determining the seismic response of subsystems are reviewed to determine compliance with the acceptance criteria of SRP Section 3.7.2, subsection 11.6. 7. Combination of Modal Responses The procedures for combining modal responses are reviewed to determine compliance with the acceptance criteria of SRP Section 3.7.2, subsec- tion II.7 when a response spectrum modal analysis method is used. 8. Interaction of Other Systems with Category I Systems The criteria used to design the interfaces between Category I and non- Category I systems are reviewed to determine compliance with the acceptance criteria of subsection 11.8 of this SRP section. 9. Multiply-Supported Equipment and Components With Distinct Inputs The criteria for the seismic analysis of multiply-supported equipment and components with distinct inputs are reviewed to determine that the criteria are in accordance with the acceptance criteria of subsection II.9 of this SRP section. 10. Use of Equivalent Vertical Static Factors Use of equivalent static factors as response loads in the vertical direc- tion for the seismic design of any Category I subsystems in lieu of a detailed dynamic method is reviewed to determine that constant static factors are used only if the structure is rigid in the vertical direction. 11. Torsional Effects of Eccentric Masses The procedures for seismic analysis of Category I subsystems are reviewed to determine compliance with the acceptance criteria of subsection II.11 of this SRP section. 12. Category I Buried Piping, Conduits, and Tunnels The analysis procedures for Category I buried piping, conduits, tunnels, and auxiliary systems are reviewed to determine that they are in accord- ance with the acceptance criteria of subsection II.12 of this SRP section. The analysis includes review of the procedures used to consider the inertial
