The Nuclear Reaction Data Centres Network (NRDC) is a world-wide cooperation of nuclear data centres, under the auspices of the International Atomic Energy Agency, established to coordinate the collection, compilation, and dissemination of nuclear data on international scale.

Dissemination of nuclear data and associated documentation to users is the primary goal of the network. In order to accomplish this goal, the following specific tasks are carried out:

• Compilation of experimental nuclear data (EXFOR/CSISRS) and bibliographic information (CINDA)
• Collection of evaluated nuclear data (ENDF/EVA);
• Exchange of nuclear data of all types among the data centres;
• Promotion of the development of special purpose evaluated data files;
• Development of common formats for computerised exchange of nuclear data;
• Coordinated development of computer software for managing and disseminating nuclear data.
• Documentation of current and future data needs in order to be able to meet changing user demands.

There are currently 13 data centres active in the Network: 4 "Core Centers" and 9 specialized data centers. See also INDC(NDS)-401.

Core Nuclear Data Centres

The core centres provide coordinated, worldwide customer services covering the entire range of nuclear data services. Data compiled and collected at these centres is exchanged on a regular basis and, therefore, the databases residing at these centers are, essentially, identical in content (with a small time delay).

Specialized Nuclear Data Centres

The specialized centres provide an essential complement to the core centres by assuming responsibility for the collection and dissemination of data of a specialised type or application. These centres do not normally provide the entire range of services offered by the Core Centres.
