the interfaces between Category I and non-Category I piping are reviewed to determine compliance with the acceptance criteria of subsection II.2.k of this SRP section. 1. Criteria used for Damping The criteria used to account for damping in systems, components, equip- ment and their supports is reviewed to determine that it is in accordance with the regulatory position in Reference 9. 3. At the CP stage, the applicant should commit to performing an analysis of the vibration of the reactor internal structures if they are designated as a prototype design. A brief description of the methods and procedures to be used for the analysis should be provided. At the OL stage, a detailed dynamic analysis should be provided for a proto- type design, to be used for vibration prediction prior to the performance of preoperational vibration tests. Acceptance of the analysis is based on the technical soundness of the analytical method and procedures used and the degree of conformance to the acceptance criteria listed above. In addition, the analysis is verified by correlation with the test results when these are available. For both CP and OL stages, if the reactor internal structures are a non- prototype design, then reference should be made to the reactor which is prototypical of the reactor being reviewed. A brief summary of test and analysis results for the prototype should be given. Alternatively, the information may be contained in another applicable document, such as a topical report, to which reference should be made. 4. At the CP stage, the staff review of the program for preoperational vibration testing of reactor internals for flow-induced vibrations includes the following matters: 6 a. The applicant should clarify his intention to perform either a pro- totype test or a non-prototype test. b. If the plant is designated as a prototype, a brief description of the preoperational vibration test program should be provided. The staff review will be based on the conformance of
