luded in leak-before-break analyses) have been evaluated by the applicant and are accommodated in the design consistently with criteria in Subsection II.5 (Acceptance Criteria) of this SRP section. 4. The deformation limits specified for these components are reviewed to verify whether the applicant has stated that these deflections will not interfere with the function of related components (e.g., control rods and standby cooling systems) and whether the stresses of these displacements are less than the specified limits for the core support structures. 5. At the operating license stage, the calculated stresses and deformations are reviewed for whether they exceed the specified limits. 6. The staff reviews the consideration of potential adverse flow effects on plant systems (including the steam dryer in BWRs) for operation up to full licensed power conditions by an applicant for the construction and operation of a nuclear power plant or by a licensee of an operating nuclear power plant proposing a power uprate license amendment or a major plant modification in accordance with criteria and procedures stated in the Appendix to this SRP Section. The staff determines whether the applicant/licensee has provided reasonable assurance that the flow-induced effects on plant systems, piping, components, and reactor internals in particular will continue to meet the GDC requirements during power ascension and long-term plant operation. 7. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed
