摘要

Method and its corresponding apparatus to monitor the irregular distributions of energy in a given plane of the nuclear reactor core, whose method includes the operations that consist of: measuring a representative parameter of the energy inside the nucleus in a predetermined number of locations within the given plane, supplying an electrical output voltage representative of the measured power at the respective predetermined locations; u and electrically perform the average of the respective measured powers, said method being characterized in that it also includes the operations consisting of: electrically summing the electrical output voltages representative of the power measured in the respective locations that deviate in a given direction of the average power measure; and comparing a representative value of the sum with a predetermined setting point to operate an alarm when the sum exceeds the set point.
