openmc.arithmetic.AggregateNuclide

class openmc.arithmetic.AggregateNuclide(nuclides=None, aggregate_op=None)

A special-purpose tally nuclide used to encapsulate an aggregate of a subset or all of tally’s nuclides for tally aggregation.

Parameters

• nuclides (Iterable of str or CrossNuclide) – The nuclides included in the aggregation

• aggregate_op (str) – The tally aggregation operator (e.g., ‘sum’, ‘avg’, etc.) used to aggregate across a tally’s nuclides with this AggregateNuclide

Variables

• nuclides (Iterable of str or CrossNuclide) – The nuclides included in the aggregation

• aggregate_op (str) – The tally aggregation operator (e.g., ‘sum’, ‘avg’, etc.) used to aggregate across a tally’s nuclides with this AggregateNuclide
