FISPACT-II comes with a suite of nuclear data libraries, including:

  • Groupwise cross section data [xs, with incident particles n,p,d,g,a,t,h]
  • Radioactive decay data [decay]
  • Fission yield data [fy (neutron-induced, spontaneous and non-neutron-induced)]
  • Self-shielding probability tables [pts]



A range of different evaluations are available for each of these data types, and FISPACT-II is distributed with the best, and most recent, evaluations from around the world. For each group cross section library, multiple temperatures may be available. Typically, these include 293 K, 600 K and 900 K, with associated self-shielding probability tables. In addition, multiple energy group discretisations are available for a selection of libraries, including the CCFE 709 and 162 groups, UKAEA 1102 and CASMO 586. You can download these from the links below.

For Release 4.0, the standard library package includes:

In addition to the release libraries, FISPACT-II can accomodate a wide range of suitably processed nuclear data. A selection of sublibrary data is provided, with links in the table below. These include a mixture of all data types, ambient temperatures, energy group discretisations and evaluation versions. For more data, or data in another format, please contact the developers.
