The HINDAS high-energy programme has provided a large amount of experimental data that has led to a better understanding of the spallation reaction mechanism and development of more reliable spallation models. These models, which have been implemented into high-energy transport codes, or sometimes directly the data, can be now used to predict with a larger confidence or, at least with a known uncertainty, some important quantities for the design of ADS spallation modules. In this paper, we present examples concerning the chemical impurities and activity induced by spallation residues in thick Pb-Bi target, after one year of irradiation by 1 GeV protons and chemical composition modifications and number of atom displacements (DPA) expected in an ADS window after one year of operation. |
