The TRADE (Triga Accelerator-Driven Experiment) experiment, to be performed in the 1 MW TRIGA reactor of the ENEA-Casaccia Centre, consists in the coupling of an external proton accelerator to a spallation target to be installed in the central channel of the reactor in subcritical configuration. The spallation target is one of the critical elements in the development of Accelerator-Driven Systems. The coupling of spallation target physics and fission reactor physics and the required technology for this component imply multidisciplinary knowledge directly coming from an accurate and rigorous assessment of nuclear parameters under different physical conditions. This work aims at evaluating, by probabilistic transport codes (MCNPX, FLUKA and EA-MC), the main target neutronic and physical parameters such as neutron yield and spectra, energy deposition, material damages and spallation product distributions, and to analyze the impact on the design criteria. An intermediate (110 MeV to 150 MeV) energy proton beam impinging on tungsten or tantalum target will be considered. The impact of different geometrical solutions of the proton beam and of the spallation target will be also studied.

Abstract
The TRADE (Triga Accelerator-Driven Experiment) experiment, to be performed in the 1 MW TRIGA reactor of the ENEA-Casaccia Centre, consists in the coupling of an external proton accelerator to a spallation target to be installed in the central channel of the reactor in subcritical configuration. The spallation target is one of the critical elements in the development of Accelerator-Driven Systems. The coupling of spallation target physics and fission reactor physics and the required technology for this component imply multidisciplinary knowledge directly coming from an accurate and rigorous assessment of nuclear parameters under different physical conditions. This work aims at evaluating, by probabilistic transport codes (MCNPX, FLUKA and EA-MC), the main target neutronic and physical parameters such as neutron yield and spectra, energy deposition, material damages and spallation product distributions, and to analyze the impact on the design criteria.
