The evaluated intermediate-energy activation cross-section library IEAF-2001 has been tested against integral experiments with SS-316 and F82H steels exposed to a white neutron flux spectrum extending up to 55 MeV. By making use of the ALARA inventory code the expected γ-active product nuclide inventories were calculated and compared with the measured one. It was found that IEAF-2001 reasonably agrees with experimental data for most of the detected radioisotopes. The reasons for some larger disagreements were found to be the uncertainty of the sample elemental composition, non-validated neutron activation reaction cross sections, and sequential charge particle reactions.

“…The induced radioactivity was repeatedly measured by a calibrated high-purity germanium detector after cooling times ranging from 1 h to 5 months. A detailed description of the experiment and measured results can be found elsewhere [6,7]. The source neutron spectrum was measured by the multi-foil dosimetry method [8].…”
