is supported by larger piping, there are two methods to evaluate this condition. Either a coupled dynamic model of the entire piping system is performed or the piping system is assumed to be broken up into two parts with the input from the larger piping system used to analyze the smaller piping system. The acceptance criteria provided in SRP 3.7.2 Subsection II.3.B is applicable. C. Piping Stress Analyses Criteria i. Seismic Input Follow the review procedures provided in SRP Section 3.9.2, Subsection III.2. 3.12-18 Revision 1 – April 2014 ii. Design Transients Follow the review procedures provided in SRP Section 3.9.1, Subsection III.1. iii. Loading and Load Combination Follow the review procedures provided in SRP Section 3.9.3, Subsection III.1. iv. Damping Values Follow the review procedures provided in SRP Section 3.9.2, Subsection III.2. v. Combination of Modal Responses Follow the review procedures provided in SRP Section 3.9.2, Subsection III.2. vi. High-Frequency Modes Follow the review procedures provided in SRP Section 3.9.2, Subsection III.2. vii. Fatigue Evaluation for ASME Code Class 1 Piping Follow the review procedures provided in SRP Section 3.9.3, Subsection III.1. viii. Fatigue Evaluation for ASME Code Class 2 and 3 Piping Follow the review procedures provided in SRP Section 3.9.3, Subsection III.1. ix. Thermal Oscillations in Piping Connected to the RCS Review the procedures to account for piping systems susceptible to thermal oscillations, cycling, and striping. Also review the development and implementation of a program to provide continued assurance of integrity of piping systems. This program should address thermal oscillations, cycling, and striping of the piping system and should address the recommendations of NRC BL 88-08. x. Thermal Stratification 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
