(note: A new comprehensive documentation of the FENDL-3.2 library is in preparation).

The Fusion Evaluated Nuclear Data Library contains reaction data with a focus on the data requirements of fusion research facilities. Both operating and future facilities (e.g., ITER,DEMO, IFMIF) data needs are covered with current data extended up to 150 MeV. Development of FENDL libraries is described in the document links provided in the left column; links to previous FENDL releases are also listed.

The IRDFF-II library (International Reactor Dosimetry and Fusion File) released by the IAEA in January 2020 is recommended for neutron dosimetry in fusion facilities.

Library Contents: Transport

The FENDL-3.2 transport package contains evaluated nuclear data in ENDF-6 format as General Purpose files. Data are given for neutron-, proton- and deuteron-induced reactions up to a typical energy of 150 MeV. Data processing for transport applications has been undertaken (neutron data processing is similar to the processing of FENDL-3.0 library described in INDC(NDS)-0611 report). More details of the FENDL-3.2 data processing will be provided in the final FENDL-3.2 paper, which is in preparation. The following processed files for applications are given:

Notes on uncertainties: If covariance data are not available for a particular element of interest, covariance data of other libraries may be used (e.g., from TENDL-2019 library).

Changes since FENDL-3.1d:

Library Contents: Activation

Activation files from FENDL-3.0/A have been adopted. Note that selected activation channels for neutron induced reactions which are included in the IRDFF-II library may contain better quality evaluations than those listed in FENDL-3.0/A. However, IRDFF-II should not be used as a comprehensive activation library as many activation reactions are not included in IRDFF-II not being neutron dosimetry reactions. A similar situation arises for many proton and deuteron induced reactions evaluated for medical radionuclide production (e.g., see evaluated data for charged-particle induced monitor reactions, for production of gamma-emitters for medical applications, for production of positron-emitters for medical applications, and for production of therapeutic radionuclides).
All those additional evaluations may contain better quality data but need to be incorporated channel-by-channel into the FENDL-3.0/A library. That work is planned.


The zipped files contain the entire library of a certain type.
