Abstract FISPACT-II is an advanced activation/transmutation and inventory code that employs the most up-to-date and sophisticated nuclear data forms, including the full TENDL-2017 library. TENDL includes residual nuclide production for incident particle energies up to 200 MeV. To address the needs of activation–transmutation simulation in incident-particle fields with energies up to and above 1 GeV, FISPACT-II has been extended to splice TENDL standard ENDF-6 nuclear data with extended nuclear data forms. Comparisons between JENDL-2007/HE, HEAD-2009, and the most recent intra-nuclear cascade models found within Geant4 led to an updated method for residual nuclide nuclear data production. This has been achieved with an automated INCL++/ABLA process that produces complete residual cross section format (MF=10) for activation/transmutation and inventory calculations. The current High-Energy Intra-Nuclear Cascade Liège-based Residual (HEIR-0.1) library includes proton-induced cross sections up to 1 GeV for 2095 targets. These data are available with the most recent release 4.0 of FISPACT-II. [ABSTRACT FROM AUTHOR]
