Nuclear Data Services
The primary goal of the NEA in this area is to disseminate nuclear data and associated documentation to member country users. In order to accomplish this goal, the NEA is currently:
- compiling experimental nuclear data;
- collecting evaluated nuclear data and bibliographic information;
- exchanging of nuclear data of all types with other data centres;
- promoting the development of special purpose evaluated data files;
- developing common formats for computerised exchange of nuclear data;
- co-ordinating the development of computer software for managing and disseminating nuclear data.
To this end, the NEA maintains and offers internet access to a number of databases containing:
- Evaluated data (about evaluated data libraries)
- Experimental data (about experimental reaction data)
- Bibliographic information (about the bibliographic database)
The same databases are accessible using the standalone JANIS application (about JANIS).
The data offered may be broadly separated into two main types;
- nuclear reaction data (the properties of interacting nuclei, e.g. cross sections);
- nuclear structure data (the properties of single nuclei).
Main projects and activities
The JEFF Project (including EFF and EAF)
The production, distribution and testing of the Joint Evaluated Fission and Fusion (JEFF) Library is a collaborative project between the countries participating in the NEA Data Bank. The JEFF-3.1 library released in May 2005 comprises sets of evaluated nuclear data, including neutron and proton interaction data, thermal scattering law data, radioactive decay data and fission yield data.
The Working Party on Evaluation Co-operation (WPEC)
The Working Party is established to promote the exchange of information on nuclear data evaluations, measurements, nuclear model calculations, validation, and related topics, and to provide a framework for co-operative activities between the participating projects.
High Priority Nuclear Data Request List (HPRL)
One of the subgroups of WPEC is responsible for drawing up the High Priority Nuclear Data Request List. This list is designed to provide guidance to those managing the measurement and evaluation programmes on the requirements for improved nuclear data for applications, primarily (but not exclusively) in nuclear power technology.
The Nuclear Reaction Data Centres (NRDC) Network
The NRDC is a world-wide co-operation of nuclear data centres, under the auspices of the International Atomic Energy Authority.
JANIS (Java-based nuclear information software)
JANIS is a display program for nuclear data. It offers flexibility for the comparison of different nuclear data sets and offers a powerful and user-friendly interface. Janis is free of charge.
