openmc.data.ThermalScatteringReaction

class openmc.data.ThermalScatteringReaction(xs, distribution)

Thermal scattering reaction

This class is used to hold the integral and differential cross sections for either elastic or inelastic thermal scattering.

Parameters:

• xs (dict of str to Function1D) – Integral cross section at each temperature

• distribution (dict of str to AngleEnergy) – Secondary angle-energy distribution at each temperature

Variables:

• xs (dict of str to Function1D) – Integral cross section at each temperature

• distribution (dict of str to AngleEnergy) – Secondary angle-energy distribution at each temperature

classmethod from_hdf5(group, name, temperatures)

Generate thermal scattering reaction data from HDF5

Parameters:

• group (h5py.Group) – HDF5 group to read from

• name ({'elastic', 'inelastic'}) – Name of the reaction to read

• temperatures (Iterable of str) – Temperatures to read

Returns:

Thermal scattering reaction data

Return type:

openmc.data.ThermalScatteringReaction

to_hdf5(group, name)

Write thermal scattering reaction to HDF5

Parameters:

• group (h5py.Group) – HDF5 group to write to
