endf-parserpy is a Python package for reading
and writing ENDF-6 files.
This functionality in combination with Python's
powerful facilities for data handling enables you to
perform various actions on ENDF-6 files, such as:
- Easily access any information
- Modify, delete and insert data
- Perform format validation
- Convert from and to other file formats, such as JSON
- Merge data from various ENDF-6 files into a single one
- Compare ENDF-6 files with meaningful reporting on differences
- Construct ENDF-6 files from scratch
The support for the ENDF-6 format is comprehensive. The package has been tested on the various sublibraries of the major nuclear data libraries, such as ENDF/B, JEFF, and JENDL. Note that the package does not support several materials in a single ENDF-6 file.
This package is available on the
Python Package Index
and can be installed using pip:
pip install endf-parserpyThe documentation is available online
@readthedocs.

for instructions on how to generate the help files locally.
The following code snippet demonstrates
how to read an ENDF-6 file, change the
AWR variable in the MF3/MT1 section
and write the modified data to a new
ENDF-6 file:
from endf_parserpy import EndfParser
parser = EndfParser()
endf_dict = parser.parsefile('input.endf')
endf_dict[3][1]['AWR'] = 99.99
parser.writefile('output.endf', endf_dict)
