General- and special-purpose JENDL data files are being produced in cooperation with the Japanese Nuclear Data Committee. Nuclear model codes have been developed in order to raise the reliability of the fourth version of JENDL General-Purpose File (JENDL-4). MA and FP data have been evaluated for JENDL-4. The capture cross section of 235U was examined in the energy region from 2 keV to 1 MeV. As a follow-up action on the previous library JENDL-3.3, covariances of several nuclei were estimated for a study on ADS. The evaluation for the 2007 versions of JENDL High Energy File (JENDL/HE) and JENDL Photonuclear Data File (JENDL/PD), which are regarded as special-purpose files, is in the final stage. Analyses of neutron transmission experiments reveal the reliability of JENDL/HE.
