N2 - Coupling neutronics to thermomechanics is important for the analysis of fast burst reactors, because the criticality study of fast burst reactors depends on the thermomechanical behavior of fuel materials. For instance, the shut down mechanism or the transition between super and sub-critical states are driven by the fuel material expansion or contraction. The material expansion or contraction is due to the temperature gradient which results from fission power. In this paper, we introduce a numerical model for coupling of neutron diffusion and thermomechanics in fast burst reactors. We perform non-dimensional analysis of the coupled system which provides insight into the behavior of the transient. We studied material behavior corresponding to different levels of reactivity insertion.
