ation Review the procedures to account for piping systems susceptible to thermal stratification. Also review the development and implementation of a program to provide continued assurance of integrity of susceptible piping systems. This program should address the recommendations of NRC BL 79-13 and BL 88-11. 3.12-19 Revision 1 – April 2014 xi. Safety Relief Valve Design, Installation, and Testing Follow the review procedures provided in SRP Section 3.9.3, Subsection III.2. xii. Functional Capability Follow the review procedures provided in SRP Section 3.9.3, Subsection III.1(C) xiii. Combination of Inertial and SAM Effects Review the piping design to ensure that when piping is supported at multiple locations within a single structure or is attached to separate structures, the piping analysis includes the effects of relative building movements at supports and anchors (seismic anchor motion), as well as the effects of seismic inertial loads. The acceptance criteria provided in SRP Section 3.9.2, Subsection II.2.G are applicable. As an alternative, the acceptance criteria provided in Section 2, “Staff recommendations on Response Combinations,” of NUREG-1061, Volume 4 may be used. xiv. OBE as a Design Load Review the design criteria used to address earthquake cycles and seismic anchor motions associated with the single earthquake design. 10 CFR Part 50, Appendix S, "Earthquake Engineering Criteria for Nuclear Power Plants," allows the use of OBE ground motion. The acceptance criteria in SRP Section 3.9.2, Subsection II.3 are applicable. xv. Welded Attachments Review the design, criteria and procedures used for the support members, connections, or attachments welded to piping to ensure compliance with the ASME Code. Acceptable Code Cases are listed in RG 1.84. xvi. Modal Damping for Composite Structures Review the procedure and analysis to account for damping in different elements of the model of a coupled system. The acceptance criteria of SRP Section 3.7.2,
