Nuclear Data Libraries for Advanced Systems: Fusion Devices (FENDL-3)(F44002)


Nuclear fusion is recognised as a long-term energy source. The most important initiative on fusion research is currently the International Thermonuclear Experimental Reactor (ITER) project, and in order to design this and ensure safe operation a wide range of Nuclear Data information is fundamental. Realization that the needs of nuclear data for fusion are different from those of fission meant that it was appropriate to produce a specific data library to address these needs. The Fusion Evaluated Nuclear Data Library (FENDL) was the response of the IAEA to the need for a fusion data library, with FENDL-1 released in 1995, FENDL-2 in 1997 and FENDL-2.1 in 2004. A need for data above 20 MeV for material testing prompted a further revision and following this successful CRP it was possible to release FENDL-3.0.

The three Research Coordination Meetings resulted in reports (INDC(NDS)-0547, INDC(NDS)-0567 and INDC(NDS)-0602). The FENDL-3.0 package contains evaluated nuclear data in ENDF-6 format both as General Purpose and Activation Files. In each case data are given for neutron-, proton- and deuteron-induced reactions up to a typical energy of 150 MeV for General Purpose and 60 MeV for Activation files. Not all targets in the General Purpose library contain covariance data and so an extract of the TENDL-2011 library with all the 180 targets of FENDL-3.0 is provided as a "shadow library" so that complete uncertainty calculations can be done. The content of the library is summarised in INDC(NDS)-0628. Processing of the basic files has been done so that a series of files are available for applications (INDC(NDS)-0611). Validation of the library has been carried out and reported in a series of reports (INDC(NDS)-0631, INDC(NED)-011 and INDC(UK)-0094.

14 research institutions have participated actively in this project from 12 Member States: Germany, Hungary, Italy, Japan, Republic of Korea, The Netherlands, Romania, Russian Federation, Slovenia, United Kingdom and United States of America.




More Information can be found at the FENDL-3 web page (www-nds.iaea.org/fendl30/) where various versions of the library can be downloaded.
