A tool to download ENDF6 nuclear data files from the IAEA website.

Installation

You can install NDFetcher with pip:

pip install git+https://github.com/nplinden/ndfetcher.git

Examples

You can use the ndfetch command to download ENDF6 nuclear data files.

To download all available sublibraries from JEFF-3.3:

ndfetch jeff33

To download a specific set of sublibraries from ENDF-B/VIII.0:

ndfetch endfb8 decay sfpy

Running those two commands in the same directory will result in the following directory structure:

endf6
├── endfb8
│   ├── decay
│   └── sfpy
└─── jeff33
    ├── decay
    ├── n
    ├── nfpy
    ├── sfpy
    └── tsl

You can then set the $ENDF6_PATH environment variable to the top directory's path to use the ndfind command. This command will search for nuclear data file paths for you:

$ ndfind jeff33 n Pu239
/home/nlinden/workspace/NuclearData/endf6/jeff33/n/n_9437_94-Pu-239.dat
