openmc.data.njoy.make_ace

openmc.data.njoy.make_ace(filename, temperatures=None, acer=True, xsdir=None, output_dir=None, pendf=False, error=0.001, broadr=True, heatr=True, gaspr=True, purr=True, evaluation=None, **kwargs)[source]

Generate incident neutron ACE file from an ENDF file

File names can be passed to [acer, xsdir, pendf, broadr, heatr, gaspr, purr] to specify the exact output for the given module. Otherwise, the files will be writen to the current directory or directory specified by output_dir. Default file names mirror the variable names, e.g. heatr output will be written to a file named heatr unless otherwise specified.

Parameters:
  • filename (str) – Path to ENDF file
  • temperatures (iterable of float, optional) – Temperatures in Kelvin to produce ACE files at. If omitted, data is produced at room temperature (293.6 K).
  • acer (bool or str, optional) – Flag indicating if acer should be run. If a string is give, write the resulting ace file to this location. Path of ACE file to write. Defaults to "ace"
  • xsdir (str, optional) – Path of xsdir file to write. Defaults to "xsdir" in the same directory as acer
  • output_dir (str, optional) – Directory to write output for requested modules. If not provided and at least one of [pendf, broadr, heatr, gaspr, purr, acer] is True, then write output files to current directory. If given, must be a path to a directory.
  • pendf (str, optional) – Path of pendf file to write. If omitted, the pendf file is not saved.
  • error (float, optional) – Fractional error tolerance for NJOY processing
  • broadr (bool or str, optional) – Indicating whether to Doppler broaden XS when running NJOY. If string, write the output tape to this file.
  • heatr (bool or str, optional) – Indicating whether to add heating kerma when running NJOY. If string, write the output tape to this file.
  • gaspr (bool or str, optional) – Indicating whether to add gas production data when running NJOY. If string, write the output tape to this file.
  • purr (bool or str, optional) – Indicating whether to add probability table when running NJOY. If string, write the output tape to this file.
  • evaluation (openmc.data.endf.Evaluation, optional) – If the ENDF file contains multiple material evaluations, this argument indicates which evaluation should be used.
  • **kwargs – Keyword arguments passed to openmc.data.njoy.run()
