Content:
on of the vibration and stress behavior of various components should be provided. Vibration interpretation should include the amplitude, frequency content, stress state, and possible effects on safety functions. There should be a detailed analysis performed of bias errors and uncertainties of instrumentation and data acquisition systems. A list of in-plant measurement issues that should be addressed by the applicant to ensure high quality data is in RG 1.20, Revision 4, Section C.2.2.2. Additional guidance for acceptable elements of the test program is below. A. Pretesting documentation provisions. (i) The vibration monitoring instrumentation should be described, including instrument types and specifications (including useful frequency and amplitude ranges) and diagrams of locations, including those with the most severe vibratory motions or the most effect on safety functions. Instrumentation should be capable of functioning in typical reactor conditions, and survive the expected duration of the testing. The data acquisition (DAQ) system should also be assessed, including connectivity of the instrumentation to the DAQ system. Routing of the instrumentation cabling should be checked to ensure that no significant electromagnetic interference occurs that could corrupt the measured electrical signals. Additional detail is available in RG 1.20, Revision 4, Section C.2.2.3, item a. (ii) The power ascension test plan should include normal operation and upset transients. The power ascension program for startup testing should include specific power level and/or flow rate plateaus with sufficiently long duration to allow data recording and reduction, comparisons with predetermined limit loading, and inspections and walkdowns for steam, feedwater, and condensate systems. The test program also should include details of actions to be taken if acceptance criteria are not satisfied. Plans should be made available for walkdown inspections and visual and nondestructive surface
