ADS Nuclear Data Library

Application Library for Accelerator Driven Systems

(August 2005)

Participants at the IAEA Technical Meeting on "Application Libraries for ADS and Transmutation", held in Vienna, 15-17 December 2004, [INDC(NDS)-0469] recommended as a first stage, the generation of a limited scope test library for Monte Carlo as well as deterministic transport codes, that can be used in the analysis of ADS. The generation of the ADS nuclear data library was undertaken by IAEA-NDS [INDC(NDS)-0474], and the data files are available to users by downloading and also as CD-ROM (upon request). For suggestions and feedbacks contact IAEA/NDS.

ADS nuclear data library includes:

ADS-ENDF: Contains selected evaluated nuclear data files in ENDF-6 format.

ADS-ACE: Contains pointwise continuous-energy cross-section data in ACE format for MCNP calculations; also includes probability tables (PT) in the unresolved resonance range, if applicable. Additionally, the SIGACE package can be downloaded for Doppler broadening of ACE-formatted file - useful for the generation of ACE-formatted files at temperatures higher than 293.6K. Thermal data for hydrogen bound in water (lwtr) is also included at eight temperatures: 293.6, 323.6, 373.6, 423.6, 473.6, 523.6, 573.6 and 623.6K.

ADS-MATXS: Contains multigroup cross-section data in MATXS format. The ORNL 421-group energy structure was used. The multi-group cross sections are given at different temperatures and Bondarenko's sigma0 values. Thermal scattering cross section is also included for hydrogen bound in water.

Data are available for 30 materials relevant for ADS benchmarking:

Elements Isotopes

For the sake of completeness, NJOY inputs to generate ACE and MATXS formatted files are supplied. Furthermore, NJOY-99.90+ local updates, as well as the auxiliary programs and WINDOWS batch files used to update and verify the ADS application library, are also available.

The work was performed by D. L. Aldama (IAEA external consultant) and A. Trkov (IAEA project officer). For more information see: "ADS-Lib/V1.0: A Test Library for Accelerator Driven Systems", INDC(NDS)-0474, D. L. Aldama and A.Trkov, 2005.
