High-energy nuclear data uncertainties propagated to MYRRHA safety parameters

A comprehensive study of spallation models for proton-induced spallation product yields utilized in transport calculation

“…In the neutronic and shielding design of high-energy accelerator facilities such as accelerator-driven systems (ADSs) and spallation neutron sources, spallation models implemented in Monte Carlo particle transport codes [1][2][3][4] provide us the information of spallation product yields, as well as energy spectra and angular distributions of secondary particles. Although an exhaustive benchmark analysis was conducted under the auspices of the International Atomic Energy Agency (IAEA) [5 ] and a great deal of effort has been devoted to improving the spallation models, discrepancies with experimental data, especially for the spallation product yields, still have been reported in recent analyses [6,7 ].…”
