Condition-based Maintenance Instrumentation Nuclear Power Plants SPRT
The authors developed an online method to monitor the condition of sensors implemented in Nuclear Power Plants. The method employs Sequential Probability Ratio Test (SPRT), and calculates log-likelihood function of each sensor readings obtained through the plant process computer to determine whether the value of the l og-likelihood function exceeds a statistically defined setpoint. A study on data collected during startup testing of a BWR power plant showed that the method wa s applicable for 1824 sensors...

Acoustic diagnosis Kernel-based PCA Probabilistic neural network
The acoustic data remotely measured by handy type microphones are investigated for monitoring and diagnosing the ball bearing type rotational machine integrity in nucle ar power plants. The present study proposes the new signal pre-processing method which normalizes the fundamental oscillation period into the same length and timing by using zero-crossing interval of filtered acoustic signal. The pre-processed signal patterns are classified by kernel-based principal component analysis (KPCA) and prob abilis...
