PROGRESS REPORT FROM THE
OECD/NEA DATA BANKAt the NRDC meeting at IAEA, Vienna, Austria
25-28 September 2006
NEA Web page: www.nea.fr
Contact: db@nea.fr

GeneralThe Data Bank’s primary role is to provide scientists in member countries with reliable nuclear
data and computer programs for use in different nuclear applications. The services include also
thermochemical data for radioactive waste management applications. The Data Bank organises
seminars and workshops to present information on computer programs or groups of programs
that are considered to be of special interest to users. Training courses on widely used computer
programs are organised a few times a year to ensure a correct and effective use of these
programs.
The Data Bank member countries are: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Italy, Japan, Republic of Korea, Mexico, Netherlands,
Norway, Portugal, Slovak Republic, Spain, Sweden, Switzerland, Turkey, and United
Kingdom. Users of the Data Bank services include governmental research institutes, industry
and universities.
The NEA Data Bank maintains a close cooperation with the NEA Nuclear Science Section,
which provides useful feedback on the performance of computer programs and nuclear data
through a number of benchmark studies, especially in the areas of reactor and fuel cycle
physics, criticality safety, and radiation shielding.
The annual meeting of the Data Bank management committee (the NEA Nuclear Science
Committee Executive Group) was held in May 2006. The two main decisions at this meetingwere to actively encourage the release of new computer codes to the Data Bank’s collection
and to extend the mandate of the Joint Evaluated Fission and Fusion (JEFF) project for theperiod 2006–2009.
Organisation
Total number of full time staff in the NEA Data Bank is 15. This is divided into 8 professional
staff and 7 support staff. However, only 5 professional and 6 support staff work with the Data
Bank services. The remaining staff is allocated to work in other parts of the NEA.
Thierry Dujardin is Director for Science and Development with Claes Nordborg and Akira
Hasegawa below him as heads of the Nuclear Science Section and the NEA Data Bank,
respectively. Within the Data Bank, Enrico Sartori is responsible for the Computer Program
Services (CPS) together with Juan Galan and Ivo Kodeli (employed by the IAEA). Hans
2

Henriksson and Yolanda Rugama are responsible for the Nuclear Data Services (NDS). The
in-house computer system is taken care of by Pierre Nagel. Yolanda Rugama, Yong-Joon
Choi and Enrico Sartori are also working part-time for the Nuclear Science Section, whereas
Federico Mompean work full time for the Thermochemical Database (TDB) project insupport of the NEA Radioactive Waste Management division. See Fig. 1 for an overview of
the NEA Data Bank professional staff (including the Nuclear Science Section).

Nuclear Data Services
The nuclear data services are mainly provided through direct on-line access to the CINDA,
EXFOR and EVA databases containing bibliographic, experimental and evaluated nuclear data
respectively. Access to all the databases is open and free of charge. The number of retrievalsfrom the NEA Web pages is between 900-1400 requests/month for EXFOR and CINDA, andabout the same for evaluated data libraries in the EVA database. See Table 1 for the numbersof retrievals of some services from the web pages during 2004-2005.

Lately, the displaying program for experimental and evaluated data, directly obtained fromWeb retrieval, has been upgraded. This online plotting facility is performed by Janis-2.2.1(released in October 2005), the software that has been developed at the NEA (see below).
In addition to these on-line services, the Data Bank also answers specific requests from
customers. Normally, this concerns requests for very large datasets, which are too large fordirect Internet download. The very large datasets are normally distributed on CD-ROM orDVD. Providing advice to nuclear data users is another important part of the nuclear dataservices.
EXFOR and CINDA compilation
More than 100 new neutron reaction experiments and almost 200 charged particle experiments
have been entered by the Data Bank into the EXFOR database since the beginning of 2005 (seeTable 2). The database is updated continuously and the delay between article publication andinclusion in EXFOR has been reduced.

The CINDA database has been subject to a major extension due to the new format, including
the insertion of charged particle references from the EXFOR database. The new CINDA
database has been tested and adopted at the NEA.
The CINDA database is available on DVD as part of the Janis package, and also on-line
through the Web. Due to a certain demand and the extension of CINDA to include charged
particle data, the NEA has decided to produce an archive version of the CINDA Book, lastissued in 1990. The new archive version is planned to be printed 2006. A draft has alreadybeen produced.
Data display tools: Janis
The nuclear data display software, Janis (JAva Nuclear Information System), developed at the
NEA Data Bank, has been available for all interested users free of charge since its first releasein 2001. Janis accesses locally stored, as well as remote, ENDF formatted evaluated data andexperimental data from the EXFOR database. The latest version of Janis (Janis-2.2.1) was
released in October 2005.
The program is free of charge and can be downloaded or launched using ‘JAVA Web Start’
from the Janis home page: http://www.nea.fr/janis, where the complete manual can be found as
well. Over 25 000 Janis requests per month for data from the NEA databases are registered in
the log files. One such request can cover one EXFOR subentry, or a full evaluated library. See
Fig. 2 for the evolution of Janis retrievals over time since January 2004.

5The Joint Evaluated Fission and Fusion (JEFF) Project and JEFF-3.1
The JEFF-3.1 Nuclear Data Library is the latest version of the Joint Evaluated Fission and
Fusion Library. The complete suite of data was released in May 2005, and contains general
purpose nuclear data evaluations compiled at the NEA Data Bank in co-operation with several
laboratories in the Data Bank member countries. Processed data for Monte Carlo code
applications was made available in spring 2006, and the full documentation of JEFF-3.1 is tobe published later this year.
The NEA High Priority Request List (HPRL)The NEA Data Bank is assisting the Nuclear Science section Working Party on international
nuclear data Evaluation Cooperation (WPEC) to manage the High Priority Request List
(HPRL), which is a compilation of the highest priority nuclear data requirements, primarily for
application in the nuclear industry. The purpose of the list is to provide a guide for thoseplanning measurements, exploring nuclear theory, and requesting high precision evaluated data
for the projects. The HPRL is a place where data users meet data producers. Three highpriority requests have been accepted after peer review by the HPRL reviewing procedure, andone general request was also accepted. All requests need to be tied to a certain project. The list
is maintained by the NEA Data Bank and is presented at: http://www.nea.fr/html/dbdata/hprl/
Computer Program Services
The computer program services distribute more than 2000 documented software packages andgroup cross-section data sets per year. The activity includes collection of programs,compilation and verification, using quality assurance methods, in an appropriate computer
environment, and that the computer program package is complete and adequately documented(see www.nea.fr/html/dbprog). The computer program collection covers a wide range of
nuclear energy and radiation physics applications.
Data from Integral Experiments
Under the guidance of the NEA Nuclear Science Committee (NSC), the Data Bank preserves
data from integral experiments to assist users in having well documented information available
for benchmark testing, especially in the context of the development of future nuclear energy
systems. Integral experimental data with benchmark quality have been compiled, reviewed andpublished. The most relevant ones for nuclear data are:- International Criticality Safety Benchmark Experiments (ICSBEP)- Radiation Shielding and Dosimetry Benchmark Experiments (SINBAD)- International Reactor Physics Experiments Evaluations (IRPhE).
Computer program training courses & tutorials 2006
The NEA Data Bank organises and participates in seminars and workshops to present
information on computer programs or groups of programs that are considered to be of special
interest to users. Training courses on widely used computer programs are organised a few
times a year to ensure a correct and effective use of them. A list of recent and planned events isgiven below.

Data Bank cooperation with other NEA divisions
Nuclear Science
The collaboration between the NEA Nuclear Science section and Data Bank is mainly in theareas of:• Reactor and fuel cycle physics, including reactor stability and transient calculations,
utilisation of MOX fuel and disposal of weapon-grade Pu, nuclear criticality safety,
nuclear waste transmutation studies and radiation shielding.
• Fuel cycle chemistry covering chemical partitioning, fuel cycle flowsheet studies andseparation criteria
The Data Bank has also developed a database, called DICE, for the International Handbook of
Evaluated Criticality Safety Experiments. The next version of DICE will be released in
September 2006. The 2006 version will contain some minor improvements, but may also
introduce new data.
Radioactive Waste Management
The Thermochemical Database project is a co-operative effort between the NEA Data Bankand the NEA Radioactive Waste Management Committee to produce internationally
recommended chemical thermodynamic data needed for the safety assessment of radioactive

7

waste disposal systems. The Project is currently supported by 17 organisations from 12 OECDmember countries.
An update to earlier reviews of thermochemical data for Uranium, Neptunium, Plutonium,
Americium, and Technetium was published in 2003. Reviews of data for Zirconium, Selenium,
Nickel and selected organic compounds have been published in 2005. A new phase of the
project has been started, covering evaluation of inorganic complexes and compounds ofThorium, Iron and Tin. The Thorium review is scheduled for publication early in 2007,
followed by the review on Tin. The project has also funded the preparation of guidelines forthe evaluation of thermodynamic data for solid solutions in the context of radioactive waste
management. The peer review on Iron is scheduled during the first semester of 2007.
Radiation Protection
The Information System on Occupational Exposure (ISOE) is a database managed at the NEA
jointly with the IAEA. ISOE provides the world’s largest database on occupational exposure at
478 commercial reactor units in 29 countries, covering some 91% of the world’s operating
commercial power reactors. Occupational exposure data collected annually from participants ismade available to ISOE members through the database. In addition to the detailed data
provided directly by participating utilities, participating authorities also contribute official
national data in cases where some of their licensees may not yet be ISOE members. The NEA
Data Bank is developing a new Internet-based system for ISOE.
Nuclear Safety
The Data Bank is safeguarding information from a number of projects within the NEA Nuclear
Safety division, such as the OECD Piping Failure Data Exchange (OPDE) Project. The goal ofthis project is to collect and analyse piping failure event data to promote a better understandingof underlying causes, the impact on operations and safety, as well as to generate qualitative
insights into the root causes of piping failure events. The OPDE project also aims at
establishing a mechanism for efficient feedback of experience gained in connection withpiping failure phenomena, including the development of defence against their occurrence.
Data Bank Computer System
An outline of the Data Bank computer system is given in figure 3 below.
The new software system for monitoring the various pieces of equipment and some basic user
services (Nagios) has been deployed and is used to detect performance issues as well as forbeing warned in case of breakdown of some critical piece of hardware.
An upgrade of the Oracle database system to version 10 is underway. This task will resolve
some problems encountered with displaying multinational character sets in the framework of
the ISOE project. The new version will also allow better handling of the failover between
different Oracle databases.
The central file storage system has been upgraded in the spring 2006. The increase in storage
space will allow all user and all application files to be consolidated into a single system. The
initial capacity will be 1 TeraByte.

Some improvements in security will be expected from the reorganisation of the subnets into
specialised firewall managed .DMZs. The main Internet DMZ will be split into a Windows OS
and a Linux OS subnet. In this way, potential weaknesses in the windows OS (in case of
attacks) will not affect the Linux servers and vice versa.
