Validation of the international reactor dosimetry and fusion file

The International Reactor Dosimetry and Fusion File (IRDFF) is an extension of the International Reactor Dosimetry File (IRDF-2002) to cover fission, fusion and accelerator driven applications up to an energy of 60 MeV and now includes 75 reactions. The Nuclear Data Section of IAEA initiates a Coordinated Research Project (CRP) with the main goal to validate and test the IRDFF library. This paper will describe the scope and present status of IRDFF as well as the objectives of the CRP, i.e. the overview of experimental data required for validation. We inform the community about this activity and draw the attention of researchers who can make a contribution.
