JENDL

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.

JENDL-1	The first Japanese evaluated nuclear data library. It contains the data important for fast breeder reactors. The neutron energy range is from 10^-5 eV ~ 15 MeV.	1977	72 nuclides

JENDL-2	The maximum neutron energy is 20 MeV. The data of structural material and heavy nuclides were revised. The data are applicable to fast breeder reactors and shielding calculations.	Dec 1982, revised in Mar 1984	84 nuclides


	The data of fission product nuclides are added.	Dec 1985	181 nuclides

JENDL-3	The data in the MeV region were modified. The data of important heavy nuclides were evaluated with the simultaneous evaluation. The γ-ray production data were given to 59 nuclides.	Dec 1989	171 nuclides

JENDL-3.1	The data of fission product nuclides were added.	Dec 1990	324 nuclides

JENDL-3.2	The data were largely improved. JENDL-3.2 is applicable to fast breeder reactors, thermal reactors, shielding, fusion neutronics, etc.	Jun 1994	340 nuclides

JENDL-3.3	Data were improved for medium-heavy and actinide nuclides. Double-differential cross sections (DDXs) and covariances were given to part of nuclides.	May 2002	337 nuclides

JENDL-4.0	The data were largely improved. The nuclides more requested from users were added. Second neutron and γ-ray data were enriched. The nuclides include covariance data were added.	May 2010	406 nuclides
