The reduction of linear models, which are attractive for the on-line control of reactor processes using symmetry considerations, is presented. Two different approaches to modeling the reactor behavior near an operating point are considered: the coupled-core model and the modal expansion approximation. The reduction procedure allows the description of the reactor dynamics by a collection of decoupled systems of equations. An example concerning a 14-region reactor is discussed.
