Japanese Evaluated Nuclear Data Library

An Evaluated Nuclear Data Library
is a data file that contains recommended nuclear data. The Nuclear Data Center (NDC) of Japan Atomic Energy Agency (JAEA) is making the Japanese Evaluated Nuclear Data Library, JENDL, with the aid of Japanese Nuclear Data Committee (JNDC).
The JENDL (Japanese Evaluated Nuclear Data Library)
was released as the first version (JENDL-1) in 1977. The latest version is JENDL-4.0 released in 2010 which contains neutron-induced reaction data for 406 nuclides, in the neutron energy range from 10-5 eV to 20 MeV. Such data files as JENDL-4.0, which provide the data for various application fields, are called "general purpose files". They contain various kinds of data in the wide energy range. We are making also JENDL special purpose files which contains only the data needed in their application field.
