its, and Tunnels. B. Piping Modeling Techniques The information presented in the SAR related to criteria and procedures for the modeling of piping systems and piping supports is reviewed. The areas of review for modeling, provided in SRP Section 3.9.2 are to be used as guidance for reviewing piping modeling techniques. The description and verification of all computer programs used for the analysis of seismic Category I piping designated as Code Class 1, 2, and 3 and non-code items are reviewed. The areas of review provided in SRP Section 3.9.1 are to be used as guidance for reviewing computer codes. The specific areas of review are: i. Computer Codes ii. Dynamic Piping Model iii. Piping Benchmark Program iv. Decoupling Criteria C. Piping Stress Analyses Criteria The information presented in the SAR related to piping stress analyses criteria are reviewed. The areas of review for piping stress analyses criteria provided in SRP Sections 3.9.1, 3.9.2, 3.9.3 are used as guidance. 3.12-3 March 2007 The specific areas of review are: i. Seismic Input ii. Design Transients iii. Loadings and Load Combinations iv. Damping Values v. Combination of Modal Responses vi. High-Frequency Modes vii. Fatigue Evaluation for ASME Code Class 1 Piping viii. Fatigue Evaluation of ASME Code Class 2 and 3 Piping ix. Thermal Oscillations in Piping Connected to the Reactor Coolant System (RCS) x. Thermal Stratification xi. Safety Relief Valve Design, Installation, and Testing xii. Functional Capability xiii. Combination of Inertial and Seismic Anchor Motion (SAM) Effects xiv. Operating Basis Earthquake (OBE) as a Design Load xv. Welded Attachments xvi. Modal Damping for Composite Structures xvii. Temperature for Thermal Analyses xviii. Intersystem Loss-of-Coolant-Accident (LOCA) xix. Effects of Environment on Fatigue Design D. Piping Support Design The information presented in the SAR related to piping support design methods, procedures and criteria is reviewed. The areas of review for piping
