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.
- 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.
