Abstract

  The importance of condition monitoring technology for sensors and equipment has increased with the introduction of condition-based maintenance in nuclear power plants. A diagnostic system must be able to distinguish between sensor drift and equipment failure. We have developed a diagnostic method using the Mahalanobis-Taguchi method for evaluating sensor drift and equipment failure. Through evaluation of several sets of simulation data we confirmed the effectiveness of the developed diagnostic method.<br>
