摘要
The mean nuclear power and the axial power difference in the core (4) of a reactor are determined, in a determination system (11), from signals supplied by two detectors, high (8) and low (10), by multiplying each of these signals by a sensitivity term in a multiplier (12, 14) preceding a matrix processing unit (16). During the calibration of this system with the aid of a reference measuring system (24) introduced into this core, only these sensitivity terms are modified, and this avoids having to modify the operating configuration of the core. The invention applies to the nuclear industry. IMAGE
