This database contains 42 research reactors performing nuclear data measurements distributed across 20 Member States.

Nuclear data are needed for innovative power reactors, basic nuclear physics research, fuel cycles, the realization of fusion reactors, material testing for reactor facilities, medical applications including radioisotope production, computer simulations of radiation doses to patients in advanced cancer therapies, and analytical techniques adopted for cultural heritage diagnostics and materials composition analysis. Research reactors continue to occupy a visible and important place in these areas of study and application, along with dedicated accelerator-based neutron sources. Additionally, the validation of the evaluated nuclear data libraries used by neutron transport and material evolution codes is also an important field for integral measurement implementation.
