openmc.deplete.d1s.time_correction_factors¶
- openmc.deplete.d1s.time_correction_factors(nuclides: list[str], timesteps: Union[Sequence[float], Sequence[tuple[float, str]]], source_rates: Union[float, Sequence[float]], timestep_units: str = 's') dict[str, numpy.ndarray][source]¶
Calculate time correction factors for the D1S method.
This function determines the time correction factor that should be applied to photon tallies as part of the D1S method.
- Parameters
nuclides (list of str) – The name of the nuclide to find the time correction for, e.g., ‘Ni65’
timesteps (iterable of float or iterable of tuple) – Array of timesteps. Note that values are not cumulative. The units are specified by the timestep_units argument when timesteps is an iterable of float. Alternatively, units can be specified for each step by passing a sequence of (value, unit) tuples.
source_rates (float or iterable of float) – Source rate in [neutron/sec] for each interval in timesteps
timestep_units ({'s', 'min', 'h', 'd', 'a'}, optional) – Units for values specified in the timesteps argument. ‘s’ means seconds, ‘min’ means minutes, ‘h’ means hours, and ‘a’ means Julian years.
- Returns
Dictionary mapping nuclide to an array of time correction factors for each time.
