RP section to steam generator internals where necessary. Future guidance updates to address review of steam generator design and performance may address this topic in further detail. • Small modular reactors were added to the reactor internals dynamic analysis review. • A list of pressurized water reactor and small modular reactor internal components were added. • The review area of reactor internals dynamic analysis and testing was updated for prototype, limited prototype and non-prototype reactors, as well as replacement internal components, to be consistent with the 2016 RG 1.20 revision. Also, the review areas were updated to reflect lessons learned from recent new reactor and EPU application reviews. • Examples of ITAAC related to dynamic analysis and testing of reactor internals specified for the ESBWR and AP1000 design certifications were added as Appendices A and B, respectively. • A pointer was added to RG 1.206. • The review interface with SRP Section 3.9.3 was edited for clarity. • A review interface was added to SRP Section 3.12. II. ACCEPTANCE CRITERIA • General Design Criterion 4 requirement was clarified to be consistent with the review scope of this SRP. • A list of potential flow-induced resonance conditions was added to the piping dynamic test program. • Referenced SRP Section 3.7.2 for the acceptance criteria for the number of discrete mass degrees of freedom in dynamic modeling. 3.9.2-45 Revision 4 – March 2017 • Clarified the sufficient number of modes in a dynamic analysis and referenced SRP Section 3.7.2. • Updated the reactor internals dynamic analysis and testing for prototype, limited prototype and non-prototype reactors to be consistent with the 2016 RG 1.20 revision. Also, the acceptance criteria were updated to reflect lessons learned from recent new reactor and EPU application reviews as incorporated in RG 1.20. III. REVIEW PROCEDURES • The review of piping seismic analysis was deleted. • Clarified the
