Abstract

PURPOSE: To detect the abnormality in many number of neutron detectors rapidly, by means of estimating true change rate of neutron flux with good accuracy by utilizing the fact that the distributed shape of neutron is not largely changed according as the core flow quantity change in a short time, and of estimating leakage current value.
