ition, the analysis is verified by correlation with the test results when available. For both CP and OL stages, applicants for extended power uprate of existing nuclear power plants should commit to a vibration analysis for the requested power uprate. For both CP and OL stages, for reactor internal structures of non-prototype design, the applicant should refer to the reactor prototypical of the reactor reviewed with a brief summary of test and analysis results for the prototype. Alternatively, the information may be in another document (e.g., a topical report) to which the applicant should refer. 4. At the CP stage, review of the program for preoperational vibration testing of reactor internals for flow-induced vibrations includes the following: A. The applicant should clarify the intention to perform either a prototype or non-prototype test. B. If the plant is designated as a prototype, or the plant is reviewed for extended power uprate, there should be a brief description of the preoperational vibration test program. The staff review will be based on compliance of this program with the requirements of subsection II.4 (Acceptance Criteria) of this SRP section. C. If the plant is a non-prototype, the applicant should refer to the prototype plant of similar design. The staff reviews the validity of the designated prototype, including any differences in the flow conditions or the design of reactor internal structures, from the prototype plant to verify whether any design modifications substantially alter the behavior of the flow transients and the response of the reactor internals. Additional detailed analysis, SMTs, or installation of some instrumentation during the confirmatory test may be required to complete the review. In addition, the applicant should commit to the prototype test if timely adequate test results are not obtained for the designated prototype. At the OL stage, the staff review includes the following procedures: A. A detailed preoperational
