Unified Nuclear Core Activity Map Reconstruction Using Heterogeneous Instruments with Data Assimilation

Evaluating the neutronic state of the whole nuclear core is a very important topic that has strong implication for nuclear core management and for security monitoring. The core state is evaluated using measurements. Usually, part of the measurements is used, and only one kind of instruments is taken into account. However, the core state evaluation should be more accurate when more measurements are collected in the core. But using information from heterogeneous sources is at glance a difficult task. This difficulty can be overcome by data assimilation techniques.
