The Serpent Monte Carlo code started out in 2004 as a simplified lattice physics code intended for generating group constants for deterministic core simulators, but the scope of applications has considerably diversified over the years. Spatial homogenization is still considered one of the main applications, but some considerable effort has also been devoted to topics like multi-physics coupling. The development of a photon transport mode, advanced geometry types and variance reduction techniques has allowed expanding the field of applications beyond fission reactor analysis, and more recent development areas are related to radiation shielding and fusion neutronics. This presentation gives a developer’s insight into the various challenges encountered during the different phases of the work, as well as some lessons learned.
