oids pressure loads on the steam dryer at plant normal operating conditions. Analysis of the as-built piping system and equipment analysis, for acoustic resonance at plant normal operating conditions, will be performed. The main steam line and SRV/SV branch piping geometry precludes first and second shear layer wave acoustic resonance conditions from occurring and results in no significant pressure loads on the steam dryer at plant normal operating conditions. Appendix B AP1000 ITAAC Related to Flow-Induced Vibration of Reactor Internals Design Control Document, Tier 1, Revision 19 Design Commitment Inspections, Tests, Analyses Acceptance Criteria AP1000 DCD Tier 1 Table 2.1.3-2 ITAAC 7 The reactor internals will withstand the effects of flow induced vibration. i) A vibration type test will be conducted on the (first unit) reactor internals representative of AP1000. ii) A pre-test inspection, a flow test and a post-test inspection will be conducted on the as-built reactor internals. i) A report exists and concludes that the (first unit) reactor internals have no observable damage or loose parts as a result of the vibration type test. ii) The as-built reactor internals have no observable damage or loose parts. 3.9.2-44 Revision 4 – March 2017 SRP Section 3.9.2 Description of Changes Section 3.9.2, “Dynamic Testing and Analysis of Systems, Structures, and Components” In addition to the changes itemized below, editorial changes were made throughout for clarity, consistency, and applicability. Changes incorporated into Revision 4 include: I. AREAS OF REVIEW • The general discussion of dynamic analysis was updated to remove specific references to steam generator internals. RG 1.20 provides information that can be useful to the staff in applying the guidance in this SRP 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
