Nuclear application data (processed libraries and tools)

In order to support the distribution and best use of the various evaluated nuclear data libraries, the NEA promotes the exchange of information on processed libraries, pre-processing and processing codes. The NEA also provides a framework for the processing of evaluated nuclear data through its nuclear data services. New libraries are always being sought and added to this listing. Available application data libraries are listed below, along with links to useful processing tools.

Workshop on Processing tools for evaluated nuclear data libraries

18 November 2008

Tools for the checking and processing of nuclear data

Several checking and processing and viewing tools exist, some of which are listed below:

Software of interest for evaluators and nuclear data users

Application data based on JEFF 3.1.1

Data processed with NJOY99.259 [NJOY-99, NJOY99_up256] in ACE format. The library was prepared by Oscar Cabellos for the general purpose and thermal scattering libraries. Date: February 2009.

Resources available:

Documentation (February 2009).
ACE files with graphs and documentation from the quality assurance procedure.
Independent ACE libraries at 300K for the General purpose file and additional temperatures for Thermal scattering data

Application data based on JEFF 3.1

Data processed with NJOY-99.90+patches in ACE format.

Date: June 2006.
The library was prepared by Oscar Cabellos for the general purpose and thermal scattering libraries. Updates are also available.

Resources available:

Documentation (May 2006).
Input parameters (NJOY inputs and patch upn).
ACE files with graphs and documentation from the quality assurance procedure.
Independent ACE libraries at 10 different temperatures (300, 400, 500, 600, 700, 800, 900, 1000, 1200 and 1800K) for both libraries: General purpose and Thermal scattering.
Correction of the thermal scattering library (HZr compound, May 2007).
Update of the library with new patch for NJOY for correct treatement of the probablity tables for the following isotopes (Fe-58; Re-185,187; U-235,238;Pu-240 and Am-241), November 2007.

Data processed with NJOY-99.112.

Date: October 2006.
This processed library was prepared by Wim Haeck and Bernard Verboomen at SCK-CEN, Belgium, with the ALEPH-DLG automation tool.

Resources available:

Documentation.
Input parameters.
ACE files and graphs.
ACE library: ACE library processed for 300K (GZ-zipped TAR-file of 270 Mb).

Other JEFF-3.1 based application data libraries.

WIMS-D library based on JEFF-3.1 from (IAEA/NDS)Andrej Trkov and Daniel Lopez de Aldama. (Libraries based on ENDF/B-VII.0 and JENDL are also available)
ADS-lib library based on JEFF-3.1 in ACE and MAXTS format from Daniel Lopez de Aldama and Andrej Trkov (IAEA/NDS).

Other application data

ENDF/B-VII.0 data processed with NJOY-99.259 for radiation damage calculations

(Including extensions to important reactions for activation.)
Date: December 2007.
The library was prepared by Oscar Cabellos (UPM, Spain).

Resources available:

Documentation.
NJOY input/outputs.
Results from applications and publications are also available (Fission and Fusion systems).
VITJ structure extended to 211 groups (up to 55MeV).

Nuclear data communities

The main evaluated nuclear data libraries in the world (JEFF, ENDF/B, JENDL, BROND, CENDL, FENDL) are collaborating under the NEA Working Party on International Nuclear Data Evaluation Co-operation (WPEC). The NEA gathers mainly European evaluators twice per year to discuss the progress in the Joint European Fission and Fusion (JEFF) project. The Cross Section Evaluation Working Group (CSEWG) at Brookhaven National Laboratory (BNL), NY, USA is meeting annually to discuss the main evaluated nuclear data format (ENDF-6) and progress in the ENDF/B project.
