Abstract
Neutron flux is measured using a subset of detectors ( ) selected from a set of detectors ( ) introduced into fuel assemblies ( ) of the core ( ) to obtain measurement signals, the number n of detectors ( ) of the subset being at most equal to 15% of the number of fuel assemblies ( ) in the core ( ), the measurement signals are processed and the instantaneous distribution of the neutron flux in the core ( ) is calculated allowing for the measurement signals. At least one operating parameter of the core is calculated from the instantaneous neutron flux distribution, and an alarm is triggered if at least one parameter is outside a fixed range. The operation of the core of the nuclear reactor can therefore be monitored virtually in real time. The neutron flux detectors ( ) introduced into the fuel assemblies of the core preferably include measuring probes consisting of collectrons.
