ABNORMALITY INDICATION MONITORING SYSTEM

WIPO Patent Application WO/2017/051574

A1

An abnormality indication monitoring system for detectably monitoring an indication of abnormality in an atomic power generation plant is provided with: a storage unit which stores plant operation data including a measurement parameter measured in the atomic power generation plant; and a monitoring and control unit which, on the basis of the plant operation data, detects an indication of abnormality in the atomic power generation plant, wherein the atomic power generation plant performs a base-load operation so that the measurement parameter has a prescribed target value, and wherein the monitoring and control unit, on the basis of past plant operation data, sets a normal range W that is a range in which the measurement parameter at the current time transitions normally, and detects an indication of abnormality when the measurement parameter at the current time exceeds the normal range W that has been set.
