High Energy Nuclear Data Evaluations for Neutron-, Proton-, and Photon-induced Reaction Data at KAERI

Abstract

The Korea Atomic Energy Research Institute (KAERI) is building high energy neutron-, proton-, and photon- induced nuclear data libraries for energies up to hundreds of MeV in response to nuclear data needs from various R&Ds and applications. The neutron library currently has 10 isotopes such as C-12, N-14, 0-16, AI-27, Si-28, Ca-40, Fe-56, Ni-58, Zr-90, Sn-120, and Pb-208 for energies from 20 up to 400 MeV. The proton nuclear data were evaluated in a consistent manner in the neutron case, using the same nuclear model parameters. In addition to the same isotopes included in the neutron library, the proton library has 70 extra isotopes of 24 elements ranging from nitrogen to lead up to 150 MeV where the evaluations are focused on the medical and activation analysis applications. The photonuclear data library has been built along with international collaboration by participating in the IAEA’s Coordinated Research Project (CRP). Currently the KAERI photonuclear library includes 143 isotopes of 39 elements.
