In this paper we explore the use of dynamic mode decomposition (DMD) for modeling the kinetics of subcritical metal systems pulsed with fast neutrons. Our ultimate purpose is to obtain a fast and accurate reduced-order model for such systems that can be used to develop an emulator. An alternative to DMD is α-eigenfunction expansions, but we show that DMD is vastly superior in several ways for the systems of interest to us.
