NUCLEAR DATA: COMPUTERISED INFORMATION SYSTEMS

1. INTERNATIONAL INFORMATION SYSTEMS

1.1 Network of Nuclear Data Centres

The Nuclear Data Centres Network is a world-wide co-operation of nuclear data centres established under the auspices of the International Atomic Energy Agency (IAEA) to co-ordinate the collection, compilation and dissemination of nuclear data at an international level. Nearly all nuclear data required for energy, non-energy nuclear applications and basic science are covered, including nuclear cross sections, fission yields and decay data. The Network consists of four ‘core’ Nuclear Data Centres, and a group of regional, national and/or specialised data centres (second group compiles data from a restricted geographical region and/or for special data types (e. g., nuclear structure data, charged particle or photon induced reactions)). Essential links have been forged through the Network to establish communications between the producers and users of nuclear data. A brief summary is given below of the various communication links for nuclear data users, with listings of standard and Internet addresses.

1.1.1 Data centres

The four main data centres compile and exchange data in the CINDA and EXFOR systems, and maintain and exchange evaluated data files for nuclear reaction, structure and decay data. Evaluated data files include general purpose files as well as specialised data files (e. g., for fission products, activation, thermonuclear fusion, and dosimetry). These data centres compile and disseminate data to customers over a defined geographical area:

National Nuclear Data Centre: United States of America, and Canada;

Nuclear Energy Agency Data Bank: OECD countries in Western Europe and Japan;

Russian Nuclear Data Centre: former Soviet countries in Europe and Asia; IAEA Nuclear Data Section: all remaining countries in Eastern Europe, South and Central America, Asia, Africa and Australasia.

The reader can contact the responsible data centre (in their relevant geographical area) for further information, or retrieve data directly via the Internet using one of the addresses given below:
