A curated list compiles open-source software relevant to nuclear science and engineering, organized by application area to help practitioners find tools for simulation, data processing, analysis, and workflows. It catalogs codes for particle transport (both Monte Carlo and deterministic), event generators, nuclear data processing, depletion/transmutation and decay, kinetics, fuel-cycle modeling, thermal-hydraulics, multiphysics coupling, molten-salt reactor work, and assorted utilities and frameworks. The collection emphasizes widely used, actively developed projects and related interoperability tools that support geometry conversion, data formats, and coupling between physics domains.
Entries include well-known Monte Carlo engines (OpenMC, Geant4, ERGnrc, FRENSIE, Warp), deterministic solvers (OpenMOC, OpenSN, BART, DRAGON), nuclear-data tools (NJOY21, FUDGE, endf-python, TALYS), depletion or burnup tools (OpenMC depletion, ONIX, ADDER), multiphysics and coupling frameworks (MOOSE, Aurora, Cardinal, ENRICO), CFD and thermal-hydraulics codes (Nek5000, nekRS, OpenFOAM), fuel-cycle and reactor analysis platforms (Cyclus, SaltProc, Moltres, PyNE, ARMI, RAVEN), and geometry/format helpers (DAGMC, MCPL, MCNPTools, serpentTools). The list also highlights contributing research groups and shows community uptake via stars and forks, making it a practical index for selecting open-source options and tracing project relationships and tooling around nuclear engineering workflows.
