Coupled electron-photon-neutron transport calculations were performed with the Monte Carlo code MCNP4C3 to model the GELINA neutron target. Our calculations were compared with measurements of the direct and moderated flux distributions and agreement was achieved within 20%. Further, the present simulations were compared with the resolution functions established earlier with a dedicated program and with measured data for 56Fe. Here too, the agreement is excellent. New IAEA photonuclear libraries were implemented to perform these calculations. The simulations crucially rely on the new MCNP4C3 photonuclear capabilities and are made efficient by using the variance reduction and TALLYX features.
