WebThis report reviews the technical status and problems associated with the on-line measurement of core power distributions in nuclear reactors. The need for and significance of the various measured and inferred quantities relating to power distribution are defined. Webnuclear power plants, it is periodically required to recalibrate the correlation between the in-core and excore nuclear instruments. The recalibration guarantees the accurate monitor-ing of incore axial power distributions by excore instrumentation.
