Content:
als are used and subcooled or saturated liquid if such fluid can be discharged under postulated transient or accident conditions. Applicants for plants utilizing suppression pools should also consider the applicable pool dynamic loads on the safety relief valve system. Stress computations and stress limits must be in accord with applicable rules of the Code. 3. Component Supports. The component support designs should provide adequate margins of safety under all combinations of loadings. The combination of loadings (including system operating transients) considered for each component support within a system, including the designation of the appropriate service stress limit for each loading combination should meet the criteria in Appendix A, Regulatory Guides (RG) 1.124 and RG 1.130 and Subsection NF of the Code. A. Component supports of active pumps and valves should be considered in context with the other features of the functionality assurance and seismic qualification program as presented in SRP Section 3.10. If the component support deformation can be expected to affect the operational readiness requirements of the supported component, then deformation limits should also be specified. Such deformation limits should be compatible with the operational readiness requirements of the supported components. These deformation limits should be incorporated into the functionality assurance and seismic qualification program.
