openmc.data.Decay¶
- class openmc.data.Decay(ev_or_filename)[source]¶
Radioactive decay data.
- Parameters
ev_or_filename (str of openmc.data.endf.Evaluation) – ENDF radioactive decay data evaluation to read from. If given as a string, it is assumed to be the filename for the ENDF file.
- Variables
average_energies (dict) – Average decay energies in eV of each type of radiation for decay heat applications.
decay_constant (uncertainties.UFloat) – Decay constant in inverse seconds.
decay_energy (uncertainties.UFloat) – Average energy in [eV] per decay for decay heat applications
half_life (uncertainties.UFloat) – Half-life of the decay in seconds.
modes (list) – Decay mode information for each mode of decay.
nuclide (dict) – Dictionary describing decaying nuclide with keys ‘name’, ‘excited_state’, ‘mass’, ‘stable’, ‘spin’, and ‘parity’.
spectra (dict) – Resulting radiation spectra for each radiation type.
sources (dict) –
Radioactive decay source distributions represented as a dictionary mapping particle types (e.g., ‘photon’) to instances of
openmc.stats.Univariate.New in version 0.13.1.
- classmethod from_endf(ev_or_filename)[source]¶
