A Numerical Model for Coupling of Neutron Diffusion and Thermomechanics in Fast Burst Reactors

We develop a numerical model for coupling of neutron diffusion and thermomechanics in order to stimulate transient behavior of a fast burst reactor. The problem involves solving a set of non-linear different equations which approximate neutron diffusion, temperature change, and material behavior. With this equation set we will model the transition from a supercritical to subcritical state and possible mechanical vibration.
