Geant4 has contributed to the IAEA nuclear spallation reactions benchmark with simulation results for all mandatory sets of data, including neutron production, light charged particle production, isotope production, excitation functions up to 3GeV, and pion production. Two hadronic multi-staged intra-nuclear cascade models were used in calculations: the Binary cascade and the Bertini intra-nuclear cascade. The Chiral Invariant Phase Space model was also used for nuclear de-excitation and isotope production. Short descriptions of the models and results of the benchmark are presented and discussed.
