Several studies show that data assimilation methods, by merging information both from model and measurement, can be used to elaborate an optimal determination of neutronic activity field within a nuclear PWR reactor core. Here the problem addressed and solved is to determine an optimal repartition of the instruments within the core, to get the best possible reconstructed field using a data assimilation procedure. The position optimization is based on simulated annealing with a Metropolis-Hasting algorithm. To perform the method in the framework of data assimilation, several algebraic optimisation related to computing time of data assimilation has been developed and are presented here.
