| Summary: | The current work aims at presenting a simple model for PBM-type reactors'
dynamic behavior analysis. The proposed model is based on point kinetics
equations coupled with feedbacks from fuel and moderator temperatures. The
temperature reactivity coefficients were obtained through MCNP code and via
available experimental data. Parameters such as heat capacity and heat
conductivity were carefully analyzed and the final system of equations was
numerically solved. The obtained results, while in partial agreement with
previously proposed models, suggest lower sensitivity to step reactivity
insertion as compared to other reactor designs and inherent safety of the
design. |
