Abstract
The object of the present invention is a method for establishing so-called “mixed IN-CORE mappings”. Its essential purpose is to compensate a loss of density of a reference instrumentation, called “RIC instrumentation” (or “RIC system”), when a significant number of locations, initially used by the sensors of the RIC system, are occupied by fixed collectron-type rods. An obvious physical interest lies in the increase of the measurement density, and thus of the level of confidence, associated with the operating results deduced from the processing of these measurements. One application of the method according to the invention concerns a collectron-type detector calibration method placed inside a nuclear reactor core.

A method of correction for a component of intrinsic uncertainty, associated with a collectron-type detector placed inside a nuclear power plant core, comprising:
- performing a calibration operation on a collectron, the calibration operation being performed when the collectron-type detector has attained a given level of wear, the calibration operation consisting of performing a three-dimensional calibration using a mapping determined by way of a reference instrumentation system.
