Abstract:

This report presents the results of tests conducted to obtain data pertaining to the hydraulic performance and structural response of the intake tower. These data would then be used to compare with findings of earlier measurements and evaluate correlations between the hydraulics and the structural responses. The test program measured wet well transition zone pressures, upper portal pressures wet well water-surface levels, and structural vibrations. Data reduction and analysis indicated that large pressure surges occurred in the wet well when closing the quality control QC valves from the full open position, a flow control shift occurred as the QC valve was opened from 2.9 to 3.0 ft and the vibration levels monitored were within the safe limits. The structural responses of the intake tower correspond well with previous vibration tests conducted at similar structures.
