## Abstract

For the design of Accelerator-Driven nuclear transmutation System (ADS), accurate cross section data are required to estimate the number of radioactive nuclides for treating radioactive wastes in the ADS plant. Although much effort has been devoted to obtaining the nuclide production cross section irradiated by protons in the energy region utilized for the ADS at several facilities so far, data with systematic uncertainties of ~10% exist. Furthermore, no experimental data still exist around for protons in a few GeV region. In order to validate the calculation code and the evaluated data utilized for the ADS, we started the experiment to obtain the cross section at 3-GeV synchrotron in J-PARC.

In this study, we obtained nuclide production cross section for targets with Z numbers from 26 to 30 (i.e. $\mathrm{{}^{nat}}$Fe, $\mathrm{{}^{nat}}$Ni, and $\mathrm{{}^{nat}}$Zn), which are important regions for the estimation of the radioactivity of the ADS structural materials. Furthermore, we investigated the incident energy dependency on the cross section from several hundred MeV to 3 GeV using the present and the previous experimental data, comparing with different intra-nuclear cascade and evaporation models of INCL4.6/GEM, INCL++/ABLA07, and Bertini/GEM, and evaluated nuclear data of JENDL-HE2007.
