the criteria used to determine whether thermal analyses of the piping systems are required. The applicant should provide the technical basis for the criteria. xviii. Intersystem LOCA Review the design features of the low pressure piping system to ensure that the low pressure piping systems that interface with RCPB is designed to withstand the full RCS pressure. The criteria provided in SRM dated June 26, 1990 in response to SECY-90-016 dated January 12, 1990 are applicable. xix. Effects of Environment on Fatigue Design Review the design criteria for the fatigue analyses of the piping system components to verify that the effects of the environment on the fatigue design of the piping systems has been addressed. The guidance provided in RG 1.207 is applicable. D. Piping Support Design i. Applicable Codes Follow the review procedures provided in SRP Section 3.9.3, Subsection III.1. ii. Jurisdictional Boundaries Review the jurisdictional boundaries between pipe supports and interface attachment points to ensure compliance with requirements of ASME Code, Section III, Subsection NF. iii. Loads and Load Combinations Follow the review procedures provided in SRP Section 3.9.3, Subsection III.1. iv. Pipe Support Baseplate and Anchor Bolt Design Review the design of the pipe support baseplates to ensure consistency with NRC BL 79-02, Revision 2. v. Use of Energy Absorbers and Limit Stops Review the design of the energy absorbers and limit stops to ensure that the design criteria have an adequate technical basis. vi. Use of Snubbers Review the design criteria, analytical considerations, modeling techniques, operational and performance testing and maintenance standards for snubbers 3.12-19 March 2007 used as a piping support. The objective of the review is to ensure that the SAR 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
