Part of the Power Systems book series (POWSYS)


Detection of impacting of detector tubes, also called instrument strings, has been a matter of interest both in Swedish and foreign BWRs. Although detection of the vibrations is relatively simple, the discovery and quantifying of the severity of impacting is far more complicated. There exists no single method that gives absolute results without the need for calibration or comparison with reference measurements.
