This is a minimal Python package that provides both command line and API interfaces for converting OpenMC h5 nuclear data files into JSON files for each reaction.
This is useful for building a nuclear data database where JSON files are commonly accepted inputs. This tool is used for the generation of the xsplot.com database.
Python API usage
Extracting a single reaction from the h5 file using the API and saving as a CSV or JSON file.
import openmc_data_to_json as odj
odj.cross_section_from_h5_to_file(
input='Li6.h5',
output='tritium_production.json',
reaction='(n,Xt)',
format='json' # csv is also acceptable
)
It is also possible to return the h5 info as a dictionary with keys for 'cross section', 'energy', 'element' and other info on the nuclius
import openmc_data_to_json as odj
reaction = odj.cross_section_from_h5_to_dict(
input='Be9.h5',
reaction='(n,2n)'
)
A h5 file can be checked for reactions to see if particular reactions exist
import openmc_data_to_json as odj
reaction = odj.reactions_in_h5(
input='Fe56.h5',
reaction='(n,g)'
)
Command line usage
Another use of this program is to extract reactions using the command line tool.
openmc-data-to-json -i Be9.h5 -r (n,2n) -o my_reaction.json
- the
-ior--inputargument specifies the input h5 file - the
-oor--outputargument specifies the output json filename - the
-ror--reactionargument specifies the reactions to extract.

The easiest way to install is to use the PyPi distribution.
