MCNP (RSICC-ONLY CCC-850)

Not distributed by NEA Data Bank

The Data Bank currently does not distribute any version of MCNP. This page provides information on other MCNP-related content.

Nuclear data

MCNP requires a complex suite of nuclear data processed using the open source NJOY software, which is actively developed by Los Alamos National Laboratories. Data is processed into A Compact ENDF (ACE) format, alongside thermal scattering data and other supplementary data.

JEFF-3.3 data

Delivered as part of the JEFF-3.3 testing, ACE files are available in at least 6 temperatures with continuous energy data. Incident alpha, deuteron, triton, gamma, He3 and proton data are provided in ACE as well for stable targets. Thermal scattering and displacement data are also provided. More information online and links.

JEFF-3.1.1 data

Delivered as part of the JEFF-3.3 testing, ACE files are available in at least 10 temperatures with continuous energy data. Incident alpha, deuteron, triton, gamma, He3 and proton data are provided in ACE as well for stable targets. Thermal scattering and displacement data are also provided. More information online and links.

JEFF-4 test data

The Joint Evaluated Fission and Fusion (JEFF) project continues to develop cutting-edge nuclear data as part of the JEFF-4 project. Test libraries are processed at the Data Bank and distributed for testing purposes as part of the library development process. Please contact us for more information.
