Japanese Evaluated Nuclear Data Library

An evaluated Nuclear Data Library is a data file that contains recommended nuclear data. The Nuclear Data Evaluation Center of Japan Atomic Energy Agency is making the Japanese Evaluated Nuclear Data Library, JENDL, with the aid of Japanese Nuclear Data Committee (JNDC).

The first version of JENDL (JENDL-1) was released 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 is also available from other WWW sites.

JENDL-1
1977
72
 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 to 20 MeV.
JENDL-2
 1982
revised in
1984		 84 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.
1985 181 The data of fission product nuclides are added.
Numerical data
JENDL-3 1989 171 The data in the MeV region were modified. The data of important heavy nuclides were evaluated with the simultaneous evaluation. The gamma-ray production data were given to 59 nuclides.
JENDL-3.1 1990 324 The data of fission product nuclides were added.
Numerical data
JENDL-3.2 1994 340 The data were largely improved. JENDL-3.2 is applicable to fast breeder reactors, thermal reactors, shielding, fusion neutronics, etc.
Numerical data
JENDL-3.3 2002 337 Data were improved for medium-heavy and actinide nuclides. Double-differential cross sections (DDXs) and covariances were given to part of nuclides.
Numerical data
JENDL-4.0 2010 406 The data were largely improved. The nuclides more requested from users were added. Second neutron and gamma-ray data were enriched. The nuclides include covariance data were added.
