e reactor internals vibration and stress tests with the analytical results from dynamic analyses of the reactor internals under steady-state and operational flow transient conditions and in particular under any adverse flow conditions. The methods should also be described by an explanation of how they will be used to correlate the results of scale model tests with those of analytical simulations or in-plant measurements. In addition, test results from plants of similar characteristics may be used to verify the mathematical models for the loading condition of LOCAs in combination with the SSE by comparing such dynamic characteristics as the natural frequencies. The staff review covers the methods for comparison of test and analytical results and for verification and validation of the analytical models. However, any differences between the plant under review and previous similar plants leading to the appearance of any flow-excited acoustic or structural resonances should be reviewed carefully. 7. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of review are identified and addressed as appropriate in accordance with SRP Section 14.3. 8. COL Action Items and Certification Requirements and Restrictions. For a DC application, the review will also address COL action items and requirements and restrictions (e.g., interface requirements and site parameters). For a COL application referencing a
