Draglib 5.1 Download Page

Draglib files on this page are open-source cross-section libraries compatible with Dragon Version 5.1. They can be downloaded from this page and laid in a directory structure similar to

Important note: Draglib 5.1 files are only compatible with Dragon 5.1. They will work with Dragon 5.0.12 after release ev4042.

All libraries were processed using NJOY-2016. Open-source Draglibs are available with the following energy meshes:

• APOLIB-99 is the APOLLO legacy energy mesh defined in France. It is used in production frameworks at EDF and Framatome.
• XMAS-172 is a legacy energy mesh defined conjointly by UK and France. It is used in many countries.
• SHEM-281 is an energy mesh defined by Alain Santamarina at CEA (France). It is used in REL-2005 computational schemes adopted at CEA and EDF.[1]
• SHEM-361 is an energy mesh defined by Alain Santamarina and Alain Hébert and obtained by refining the group structure of SHEM-281 in the resolved energy domain, above 22.5eV.[2]
• SHEM-295 is an energy mesh defined by Alain Hébert at Polytechnique Montréal. Is is obtained from SHEM-361 by defining coarse energy groups between 4.6 and 22.5 eV.
• SHEM-315 is an energy mesh defined by Alain Hébert at Polytechnique Montréal. Is is obtained from SHEM-295 by refining the energy groups between 1 and 10 keV and by moving some energy limits so that SHEM-315 is a superset of the ERANOS 33-group mesh.
• ECCO-1962 is an energy mesh defined by Gérald Rimpault at CEA (France) and dedicated to fast reactor systems. It features a uniform energy mesh at 1/120 lethargy width above 5 eV. It is a superset of the ERANOS 33-group mesh. Only a few isotopes were processed in this format.

• Little-endian libraries. These libraries are used on Intel, AMD, ARM and Alpha systems.

• ASCII-formatted libraries. These libraries are available in LCM-export format, as produced by PyNjoy. To convert a library to binary, you have to follow the instructions from the PyNjoy tutorial (PDF).

• The following PyNJOY data files are provided in case you want to run NJOY-2016 via the PyNJOY system and make a Draglib by yourself. Processing a single evaluation for a single energy mesh takes around 5 to 10 hour of CPU time. The above datafiles are creating the Draglib on the /tmp directory of the workstation, in order to save CPU resources. These dataset also provide information about the library content.
