Nuclear data activities at the NEA Data Bank

Abstract

The OECD Nuclear Energy Agency (NEA) Data Bank is an international centre of reference for its member countries with respect to basic nuclear tools, such as computer codes and nuclear data. The Data Bank is part of an international network of data centres in charge of the compilation and dissemination of basic nuclear data. The NEA nuclear data services include the collection of data, validation and distribution of the Nuclear Data libraries via the NEA website, offering easy access to databases containing bibliographical and experimental information, as well as evaluated libraries, e.g., the Joint Evaluated Fission and Fusion (JEFF) library. The selection and distribution of chemical thermodynamic data for radioactive waste management applications is the subject of the Thermochemical Database Project (TDB), supported by 17 organisations in 12 member countries and co-ordinated by the NEA Data Bank. In support of data evaluation, and generation of project oriented data libraries, relevant computer codes in the field of nuclear models, experimental data processing and evaluated data processing are made available to experts with the support of the member countries. Large collections of benchmark experiments for data and code validation are also available from the NEA in areas such as criticality safety (ICSBEP), radiation shielding (SINBAD), fuel performance (IFPE) and reactor physics (IRPhE). The NEA Working Party on international nuclear data Evaluation Co-operation (WPEC) provides a framework for co-operative activities between the six major evaluation projects (BROND, CENDL, ENDF, FENDL, JEFF and JENDL).
