On 12 May 2011, the NEA Data Bank welcomed its new Head, Mr. Kiyoshi Matsumoto. Before joining the NEA, he was the General Manager of the Centre for Computational Science and e-Systems at the Japan Atomic Energy Agency (JAEA). Mr. Matsumoto has also worked for Sandia National Laboratory in the United States (specialising in nuclear power plant safety) and the Korean Peninsula Energy Development Organisation (KEDO) in New York.
Experimental Data – The EXFOR database contains experimental data from neutron and charged particle induced reactions. It is maintained by the international network of Nuclear Reaction Data Centres (NRDC), which includes the NEA Data Bank. Data recently published in peer-reviewed journals have been compiled in the following EXFOR entries (this list is limited to new entries from the NEA Data Bank and does not show all recent updates to EXFOR).

Evaluated Data – The Joint Evaluated Fission and Fusion (JEFF) project is a collaborative effort among NEA Data Bank participating countries to compile, maintain and develop a reference nuclear data library for use in different energy applications. Currently, the JEFF collaboration efforts are focused on the development of its next major release, the JEFF-3.2 library, which will implement more and further improved nuclear data, including new actinide evaluations. JEFF-3.2 is expected for official release in 2013. In preparation of this release a starter library, JEFF-3.2T1 was distributed in May 2011 and is currently being tested. A shorter-term release will be a minor update of the JEFF.3.1.1 library, which will be named JEFF-3.1.2 and is expected in the fall of 2011.
The NEA Working Party on International Nuclear Data Evaluation Co-operation (WPEC) provides a worldwide framework for co-operative activities between major nuclear data evaluation projects. New reports were recently published by two Working Party subgroups.
Subgroup 32 (SG32) was established to assess the methodologies used in the unresolved resonance region for cross-section and covariance representation. The final SG32 report describes investigations made on the use of the single-level Breit-Wigner formalism in this energy region and recommends improving the cross-section and covariance representation in the ENDF format. WPEC Subgroup 33 (SG33) studies methods and issues in the combined use of integral experiments and covariance data with the objective of recommending a set of best and consistent practices in order to improve evaluated nuclear data files. The intermediate SG33 report reviews and assesses the existing nuclear data adjustment methodologies.
The last computer codes, processed data libraries and compiled integral experiments acquired since the last Newsletter are:

The 2011 edition of the International Criticality Safety Benchmark Experiments Project (ICSBEP) handbook will be available shortly. The evaluated criticality safety benchmark data are given in nine volumes. These volumes span over 58,000 pages and contain 533 evaluations with benchmark specifications for 4,551 critical, near critical, or subcritical configurations, 24 criticality alarm placement / shielding configurations with multiple dose points for each, and 200 configurations that have been categorised as fundamental physics measurements that are relevant to criticality safety applications. The DVD may be obtained by requesting a copy via the Idaho National Laboratory website.
Mandates for all four of the WPRS Expert Groups have been drafted, reviewed and were approved at the June 2011 Nuclear Science Committee Meeting.
The groups are:
A key activity for each of these groups is to coordinate the development of the Integral Experiments Databases for Fuel Performance (IFPE), Reactor Physics (IRPhE) and Radiation Shielding (SINBAD).
As part of the NEA’s commitment to knowledge management, a new database is under construction based on the data within the International Reactor Physics Experiments Handbook. In conjunction with the creation of the database, a database tool is being developed to facilitate the identification, retrieval and analysis of the information stored in the database. Building on the success of DICE (Database for the International Criticality Safety Benchmark Evaluation Project), the database will incorporate features that allow users to identify experimental information relevant to their particular application. As in DICE, the user will be able to query based on parameters such geometry as well as calculated quantities, for instance, reactor spectrum and reaction rates. Currently the design specifications of the database and tool have been drafted, and a prototype is planned for demonstration at the October 2011 IRPhE meeting.
The 2011 version of the IRPhE Handbook was published in June 2011. The Handbook can be requested by accessing the corresponding IRPhEP web pages filling in the REQUEST FORM. It is distributed on DVD. The IRPhEP Handbook is available to authorised requesters from the OECD member countries and to contributing establishments from non-OECD countries. Other requests are handled on a case by case basis.
The Expert Group on Uncertainty Analysis has organised a series of workshops on the modeling of transients in LWRs in Stockholm during May 2011. Summary records and copies of workshop presentations are available on the NEA Nuclear Science Website: http://www.oecd-nea.org/science/wprs/eguam/.
Class sizes are limited and courses may be cancelled if minimum enrolment is not obtained one month prior to course. Course fee is refundable up to one month before each class. After one month, course fee will not be refunded.
Note that all attendees must be registered users.
