The JENDL PKA/KERMA File is prepared from the evaluated nuclear data file, for radiation damage calculations used to support programs such as the International Fusion Material Irradiation Facility (IFMIF). The file contains primary knock-on atom (PKA) spectra, KERMA factors and displacement-per-atom (DPA) cross sections for 78 isotopes of 29 elements in the energy range between 10-5 eV and 50 MeV. The processing code system, ESPERANT, was developed to calculate quantities of PKA, KERMA and DPA from evaluated nuclear data for medium and heavy elements by using an effective single-particle emission approximation (ESPEA). For light elements such as Li, Be, B, C, N and O, the PKA spectra are evaluated by the SCINFUL/DDX and EXIFON codes, simultaneously with other neutron cross sections.
