NEA Data Bank has developed and released the JEF-PC program, in co-operation with CSNSM-Orsay and the University of Birmingham. This jointly-developed program generates a “Chart of the Nuclides” format for the display of data from a number of evaluated libraries, including the Joint Evaluated File (JEF-2.2), ENDF/B — VI.4 and JENDL-3.2 supplied on CD-ROM as part of the package. Three internal modules are devoted to radioactive decay, fission product yields and cross-section data (Konieczny et al., 1997). Evaluated and experimental cross-section data can also be plotted and compared.

JANIS (JAva Nuclear data Information System) is in the process of being developed by the NEA Data Bank on the basis of user feed-back from JEF-PC. All earlier features of JEF-PC have been reproduced, along with several others (e. g., energy and angular distribution, and display of resonance parameters). This new software is more flexible and user-friendly, and is undergoing preliminary tests (Nouri et al., 2001).
