A mathematical model explaining the dynamics of the Sodium Reactor Experiment (SRE) Core II, prior to constraint of the fuel clusters, is presented and is shown to match the measured SRF behavior. The model uses an axial space- independent, nodal approach, postulating separate coolant flow regions inside and outside the fuel cluster, plus a "mixing flow'' between them. The model reproduces the power coefficient and flux oscillations by demonstrating the effect of the mixing flow on fuel-rod bowing.
