Abstract

PURPOSE:To detect an abnormal measuring apparatus without a change of output of the reactor by detecting an abnormal swing of reading of the apparatus. CONSTITUTION:Readings of a multiplicity of apparatus 2 placed in the core of reactor 1 are periodically sampled by the data sampling unit 3, and are stored in the memory 4. The stored data is fed to the deviation calculator 5 to compute the deviation. The computed deviation is sent to the discriminator 6, the apparatus which show extremely little and large values of deviations are decided abnormal. An abnormal deviation shown by the discriminator is finally displayed on the display unit 7.
