existing SRP Section 3.9.5 wording (esp. "as appropriate") and determined that it provides sufficient flexibility to remain consistent with implementation of any changes to other SRP Sections. 14. SRP-UDP format item Added Review Interface subsection of Areas of Review using numbered paragraphs to be consistent with SRP-UDP required format so that reviews performed by the SRP Section 3.9.5 PRB in other SRP Sections which are relevant to the overall review of reactor internals are detailed in their own subsection. 15. Integrated Impact 292 Added Review Interface to SRP Section 3.6.2 since II 292 recommends modification of Review Procedures to clarify that asymmetric loadings should be considered. Pipe rupture locations producing design basis asymmetric loadings are reviewed by EMEB under SRP Section 3.6.2. 16. PI 24332 Added review interface to SRP section 3.9.1. The ABWR FSER indicates that the staff's evaluation of criteria for the design reactor internals under normal, upset, emergency, and faulted loading conditions is discussed in FSER sections 3.9.1, 3.9.2.4, and 3.9.3.1. 17. Integrated Impact 291 Added Review Interface description to address reviews related to the 60-year design life of evolutionary plants including the verification of adequate conservativism/margin in the design to account for added cyclic effects on the fatigue resistance of materials used in reactor internals (including bolting) over this longer life. SRP Section 3.9.1 is the section where the adequacy of identification of service lifetime cyclic loadings for certain Code class components and supports is reviewed. No review procedures are added to SRP section 3.9.5 as recommended in the II since criteria and details of Code class component and support fatigue design reviews are to be located in SRP sections 3.9.1 and 3.9.3.
