Abstract

The number of applications of the Monte Carlo method augmented with the increase of computers speed and the growth of high performance parallel computing platforms. Monte Carlo calculations are no longer used to only obtain the kinetics parameters of reactor cores but also to perform advanced analyses such as burnup performances, power tallying in unstructured meshes for use in thermal-hydraulic or material science calculations, or moving geometry transients. This study focuses on the last application and compares the power
measured at the GIACINT facility of Belarus during a control rod insertion with the results obtained from SERPENT simulations. The SERPENT computer program allows for the simultaneous use of MPI and OPENMP parallel computing platforms. The use of 2,034 cores in parallel allowed to simulate a control rod transient in 15 hours producing results that are in good agreement with experimental data. The present analyses focus on a transient where the control rod moves with a constant speed by an engine; future studies will be dedicated to control rods dropped under gravity that experience water buoyancy forces.
