FISPACT-IIFISPACT-II is an enhanced multiphysics platform providing a wide variety of advanced simulation methods and employing the most up-to-date and complete nuclear data for both neutron and charged-particle interactions.

FISPACT-II has been developed and is maintained by the United Kingdom Atomic Energy Authority at Culham. As a comprehensive, modern object-oriented Fortran code, FISPACT-II fully processes all ENDF-6 nuclear data including the complete TENDL data with full covariances files. This extends the physics up to GeV energy with all channels and incident/emitted particles. Code features include self-shielding factors, broad temperature dependence, thin/thick target yields, robust pathway analysis, Monte-Carlo sensitivity and uncertainty quantification and propagation using full covariance data.

The latest generation of processing codes PREPRO, NJOY and CALENDF are used to provide the user with the most sophisticated incident-particle nuclear data from the TENDL-2014, ENDF/B.VII.1, JENDL-4.0 and JEFF-3.2 international libraries, which is complemented with the latest decay and fission yield data, including the most recent GEF libraries. The maturity of modern, technological nuclear data including TENDL and GEF provides truly comprehensive data for all simulation requirements. The result is a multiphysics platform that can accommodate the needs of all nuclear applications including: activation, transmutation, depletion, burn-up, decays, source definition, full inventories, dpa, kerma, primary damage (PKA) spectra, gas/radionuclide production and more.

FISPACT-II is a true 21st century simulation platform of observables for nuclear sciences and technology, with applications in:

  • Magnetic and inertial confinement fusion
  • Advanced fission Gen IV and beyond
  • Advanced energy and fuel systems
  • High energy and accelerator physics
  • Medical applications, isotope production
  • Earth exploration, astrophysics
  • Homeland security
  • And more…
