Abstract: Spallation reactions provide the neutrons which are useful for fundamental research and for several desired applications. It is specifically dedicated to applied research with a neutron flux for driving the subcritical nuclear reactors also for the transmutation of nuclear wastes. The choice of spallation target remains as a nuclear research activity that is more efficient, more adaptable and more coherent to the parameters related to theory and practice through the MC simulation. In this research, we investigated cylindrical spallation targets: beryllium, tin, lead, tungsten, and uranium, which are bombarded by high-energy proton beams. In this work, we focused on the target type of accelerator-driven systems by calculating important parameters such as yield, current, and neutron spectrum using the MCNP code and comparing the results found with theoretical and experimental results, to approve the proper application of an ADS project.

Keywords: yield neutron; spallation; high-energy; accelerator-driven-system; Monte Carlo; transmutation; MCNP.
