The CIELO Pilot Project (OECD/NEA WPEC SG-40) was successful and produced new evaluated data files for materials important for fission reactor application. The IAEA contribution to the CIELO project was significant. Several evaluated data files produced within the project were adopted for the ENDF/B-VIII.0 and JEFF-3.3 libraries, which were officially released in 2018 and 2019, respectively. Since then, many benchmarking results became available and new/updated evaluations have been requested to correct identified shortcomings and to extend the scope of nuclides under consideration.

The overall objective of INDEN is to apply the scheme of broad international collaboration to improve both the evaluation methodology as well as to produce new (updated) evaluated nuclear data files in a manner used within the CIELO project of the OECD/NEA.

The network is managed through a series of Meetings, traditionally held at the IAEA Headquarters in Vienna. Usually, three meetings are organised per year, addressing i) light nuclei (INDEN-LE), ii) structural materials and iii) resonant absorbers and actinides. There are links to the web pages of the Meetings in the list of IAEA Meetings. (Search for the "INDEN" string on the web page).

The archive of some of updated evaluated data files including processed ACE libraries and selected analysis reports are available from the tabs below.

Updated evaluated data files, processed ACE libraries and selected analysis reports. Every file below is a record in this repository, so it can also be found through the search page and filtered by element.
