krakentools.utils.write_water_composition(fresh_water_mass_density, boron_in_ppm_weight, temperature, fout=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='utf-8'>, fname=None, thermlibs=[], mat_name='', lowest_library_temperature=0, highest_library_temperature=1800)

Writes water material card and optionally the therm-card for Serpent into a file for a specific state point (fresh water density + boron ppm)

Parameters:

  • -- (temperature {float}) – target mass density of non-borated water (positive number, g/cm3)

  • -- – boron concentration in ppm weight

  • -- – water temperature in Kelvin

Keyword Arguments:

  • -- (highest_library_temperature {int}) – Handle to a pre-opened file into which the water composition will be written (default: {stdout})

  • -- – Optional name of file into which the water composition will be written (default: {None})

  • -- – A list of (thermal scattering library identifier)-(temperature) pairs (default: {None})

  • -- – Name for the created material (default: {“”}, will be created based on state point)

  • -- – Lowest cross section library temperature (default: {0 K})

  • -- – Highest cross section library temperature (default: {1800 K})

Raises:

  • RuntimeError – If the target temperature is not bracketed by the thermal scattering libraries.

  • RuntimeError – If lowest_library_temperature > highest_library_temperature.

  • RuntimeError – If temperature < lowest_library_temperature.

Return type:

None
