-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 this program to the requirements as listed in subsection II.4, above. c. If the plant is a non-prototype, the applicant should identify the existing plant of similar design that is the prototype plant. The staff reviews the validity of the designated prototype, including any design difference of reactor internal structures from the proto- type plant to verify that any design modifications do not substantially alter the behavior of the flow transients and the response of the reactor internals. Additional detailed analysis, scaled model tests, or installation of some instrumentation during the confirmatory test may be required in order to complete the review. In addition, the applicant should commit to performing the prototype test if adequate test results are not obtained on a timely Basis for the designated prototype. 3. 9.2-18 . Rev. 2 - July 1981 At the OL stage, the staff review includes the following procedures: (1) A detailed preoperational vibration test program and the tentative schedule to perform the test are reviewed. If elements of the pro- gram differ substantially from the guidelines specified in Regulatory Guide 1.20, discussion of the need and justification for the dif- ferences should be given. On request, RSB verifies that the flow modes to be used are acceptable. (2) For a prototype plant, the review covers the acceptability of vibra- tion prediction, the visual surface inspection procedures, the details of instrumentation for vibration monitoring, the methods and pro- cedures to process the test results, and possible supplementary tests, such as component vibration tests, flow tests, and scaled model tests. (3) For a nonprototype plant, the staff verifies the applicability of the designated prototype, including the design similarity of the reactor
