ternals and unbroken loops of the reactor coolant piping to withstand the loads from a loss-of-coolant accident (LOCA) in combination with the SSE. The staff review covers the methods of analysis, the considerations in defining the mathematical models, the descriptions of the forcing functions, the calculational scheme, the acceptance criteria, and the interpretation of analytical results. 6. A discussion should be provided which describes the methods to be used to correlate results from the reactor internals vibration test with the analytical results from dynamic analyses of the reactor internals under steady-state and operational flow transient conditions. In addition, test results from previous plants of similar characteristics may be used to verify the mathematical models used for the loading con- dition of LOCA in combination with the SSE by comparing such dynamic characteristics as the natural frequencies. The staff review covers the methods to be used for comparison of test and analytical results and for verification of the analytical models. Computer programs used in the analyses discussed in this SRP section are reviewed in accordance with SRP Section 3.9.1. The Reactor Systems Branch (RSB) verifies on request that (1) the various flow modes to be used to conduct the vibration test of the reactor internals are representative of the steady-state and operational transient conditions anticipated for the reactor during its service, and (2) that an acceptable hydraulic analysis has been used to determine the loads acting on the reactor coolant system piping and the reactor internals. II. ACCEPTANCE CRITERIA MEB acceptance criteria are based on meeting the relevant requirements set forth in General Design Criteria 1, 2, 4, 14 and 15. The relevant require- ments are as follows: A. General Design Criterion 1, as it relates to the testing and analysis of systems, components, and equipment with appropriate safety functions being performed to appropriate quality
