Data Storage#

Nuclear data libraries installed with NDFetcher are stored in the path specified by the NDMANAGER_ENDF6 variable. In this directory, librarie are stored using the following structure:

# Directory structure for the foo library
$NDMANAGER_ENDF6
└──foo
   ├── ard
   │   ├── C.endf6
   │   ├── H.endf6
   │   └── Pu.endf6
   ├── n

   └── tsl
       ├── tsl_0002_para-H.endf6
       └── tsl_0037_H(CH2).endf6

Notice that ENDF6 tape are renamed using the {gnds_name}.endf6 format if they are nuclide-specific, and to the {element_name}.endf6 format if they are element-specific. TSL files keep their original name but their extension is set to .endf6 to clearly identify them as ENDF6 tapes.
