R contains adequate discussions and commitments to address the criteria specified in SRP 3.9.3, Subsection II.3.(b) paragraphs (1) through (6). vii. Pipe Support Stiffness Follow the review procedures provided in SRP Section 3.9.3, Subsection III.3. viii. Seismic Self-Weight Excitation Review the procedure used to evaluate the mass of the pipe supports and miscellaneous steel as a self-weight excitation loading on the steel and the structures supporting the steel to verify that these loads have been addressed. ix. Design of Supplementary Steel Review the procedure used for the design of supplementary structural steel to verify the design is in accordance with the provisions of ASME Code, Section III, Subsection NF. x. Consideration of Friction Forces Review the procedure used in the analysis of sliding type supports to consider friction loads induced by the pipe on the supports. Review the coefficients of friction used in the evaluation to ensure that these are reasonable values commonly used in the nuclear industry. xi. Pipe Support Gaps and Clearances Review the procedure used to assess the design for the minimum gap (total of opposing sides) between the pipe and the support to verify that the temperature and pressure of the pipe have been adequately addressed. xii. Instrumentation Line Support Criteria Follow the review procedures provided in SRP Section 3.9.3, Subsection III.3. xiii. Pipe Deflection Limits Review the procedure to determine allowable deflections of the piping at support locations for static and dynamic loading to verify that the applicant has an adequate technical basis for the criteria. 5. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The
