to demonstrate that adverse flow, mechanical, and acoustic excitation mechanisms expected during all steady state and anticipated transient conditions that correspond to preoperational, startup test, and normal operating conditions will not cause excessive vibrations or structural damage. The NRC staff reviews the test program description to ensure it includes all potential plant operating conditions (such as pressures, flow rates, and temperatures), potential flow-induced resonance behavior, mechanical and acoustic sources, sensor types and locations (and how the locations are connected to key response regions identified by the analyses), a description of test procedures and methods to be used to process and interpret the measured data including bias errors and uncertainties, a description of the visual inspections to be made, planned comparisons of the test results with the analytical predictions along with acceptability criteria, and plans for updating and correcting the analyses based on the monitoring results. The following areas related to the dynamic response analysis are reviewed along with their bias errors and uncertainties. For more details, refer to RG 1.20, Revision 4, Section C.2. A. Pre-testing documentation. The pre-testing documentation and test plan should provide assurance that accurate and reliable measurements will be made, and 3.9.2-10 Revision 4 – March 2017 that the provisions listed in RG 1.20, Revision 4, Section C.2.2.3 are met. They include the items below. (i) Instrumentation types, locations, anticipated life, and planned use (validation of analyses, limits on vibration or stress). The end-to-end bias errors and uncertainties associated with the overall measurement procedures should be reviewed. RG 1.20, Revision 4, Section C.2.2.2 contains additional guidance related to in-plant measurement issues. (ii) The power ascension plan, including planned operating conditions, measurement conditions, flow rates, and power levels, limits, and
