ctor internal structures and unbroken loops to withstand dynamic loads from the most severe LOCA in combination with the SSE. The staff review includes the analytical methods and procedures, the basis of the forcing functions, the mathematical models to represent the dynamic system, and the stability investigations for the core barrel and essential compressive elements. Acceptance of the analysis is based on (1) the technical soundness of the analytical methods, (2) the degree of compliance with the acceptance criteria listed, and (3) verification that stresses under the combined loads are within allowable limits of the applicable code and deformations are within the limits set to ensure the ability of reactor internal structures and piping to perform needed safety functions. On request from primary reviewer, the reviewer verifies whether an acceptable hydraulic analysis has been used. 6. The program that the applicant has committed to implement as part of the preoperational test procedure is reviewed principally to correlate the test measurements with the analytically predicted flow-induced dynamic response of the reactor internals. The applicant's statements in this area are reviewed for a commitment to submit a timely report. The report should summarize the analyses and test results for review of the compatibility of the results from tests and analyses, the consistency between mathematical models for different loadings, and the validity of the interpretation of the test and analysis results. 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
