Data Bank
The Data Bank operates as an international centre of reference for its member countries with
respect to basic nuclear tools, such as computer codes and nuclear data, used for the analysis and
prediction of phenomena in the nuclear field. It provides a direct service to its users by acquiring,
developing, improving and validating these tools and making them available upon request.
Highlights
• Seven workshops and training courses on the most popular computer codes were organised as
part of the knowledge management activities of the NEA Data Bank.
• The Computer Program Service sent out its 100 000 th package since its inception in 1964.
• A new version of the nuclear data display program, JANIS 3.4, was released online and on DVD
together with an exhaustive compilation of cross-section curves and tabulated key quantities;
the compilation is known as the “JANIS Book”.
• The JEFF-3.1.2 General Purpose Library was released online and on DVD with special purpose
files and application libraries.
Computer program services
The Data Bank collection contains more than
2 500 computer programs and 400 integral experiments
covering all areas from reactor design, dynamics,
safety and radiation shielding to material behaviour
and nuclear waste applications. Twenty-eight
new versions of computer programs and 32 integral
experiments were added to the collection in 2012.
A total of 1 019 computer program packages were
dispatched upon request in 2012 to the Data Bank
member countries and, through the co-operative
agreement between the NEA Data Bank and the
International Atomic Energy Agency (IAEA), to
authorised non-OECD member countries having access
to these services. The current co-operative arrangement
between the United States Department of Energy and
the NEA, signed in 2006, authorises the NEA Data Bank
to issue user licenses and distribute the US computer
codes to the Data Bank member countries.
On 5 March, the Data Bank sent out its
100 000 th package since the Computer Program
Service started in 1964. The package was sent to
the Korean Institute of Nuclear Safety. It was a
program contributed by the US Energy Science and
Technology Software Centre.
The number of officially nominated establishments
using the Computer Program Service in NEA
Data Bank member countries is 937, and 77 establishments
in other countries.
Detailed information about material available from
the Computer Program Services can be accessed via
the NEA website at www.oecd-nea.org/dbprog/. News
on updates is provided in an electronic newsletter.
Knowledge transfer and preservation of
information from integral experiments
As an important complement to the Computer
Program Service, the Data Bank organises workshops
and training courses on the utilisation of the most
popular computer programs. Seven workshops/training
courses were organised during 2012, attended by
more than 100 participants. Subjects covered many
different areas including computational radiation
physics, criticality safety and radiation shielding,
radiation transport using Monte-Carlo codes and
sensitivity/uncertainty analysis.
Under the scientific guidance of the NEA Nuclear
Science Committee, the Data Bank verifies, preserves
and disseminates well-documented integral
data in the following areas: integral shielding experiments
(SINBAD), International Fuel Performance
Experiments (IFPE), the International Criticality
Safety Benchmark Evaluation Project (ICSBEP)
and the International Reactor Physics Benchmark
Experiments (IRPhE). More than 1 000 sets were distributed
upon request in 2012.
The Data Bank also assists other parts of the NEA,
especially in the area of knowledge preservation. In
co-operation with the NEA Nuclear Safety Division,
experimental data from several international joint
projects are maintained and distributed.
Nuclear data services
Using the Java-based nuclear information software
(JANIS), designed by the Data Bank to facilitate the
visualisation, comparison and manipulation of
nuclear data libraries, users can locally or remotely
access a comprehensive choice of evaluated
(e.g. ENDF/B, JEFF, JENDL), experimental (EXFOR) and
bibliographical (CINDA) data sets.
In June 2012, JANIS 3.4 was released online and
on DVD, together with the most recent evaluated
nuclear data libraries. Using the latest version of
the JANIS software and database, the Data Bank also
made available a compilation of cross-section curves
and tabulated key values for neutron-, photon- and
30 Technical Programmes
