JENDL
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-5 released in 2021 which contains the nuclear data of 795 nuclides for neutron-induced reactions. Such data files as JENDL-5 are called "General purpose files", which provide vaious kinds of data for wide application fields. We are also making "Special purpose files", which contains only the data needed in their application field.
