openmc.deplete.FissionYield¶
- class openmc.deplete.FissionYield(products, yields)[source]¶
Mapping for fission yields of a parent at a specific energy
Separated to support nested dictionary-like behavior for
FissionYieldDistribution, and allowing math operations on a single vector of yields. Can in turn be used like a dictionary to fetch fission yields. Supports multiplication of a scalar to scale the fission yields and addition of another set of yields.Does not support resizing / inserting new products that do not exist.
- Parameters
products (tuple of str) – Sorted products for this specific distribution
yields (numpy.ndarray) – Fission product yields for each product in
products
- Variables
products (tuple of str) – Products for this specific distribution
yields (numpy.ndarray) – Fission product yields for each product in
products
Examples
>>> import numpy >>> fy_vector = FissionYield( ... ("I129", "Sm149", "Xe135"), ... numpy.array((0.001, 0.0003, 0.002))) >>> fy_vector["Xe135"] 0.002 >>> new = FissionYield(fy_vector.products, fy_vector.yields.copy()) >>> fy_vector *= 2 >>> fy_vector["Xe135"] 0.004 >>> new["Xe135"] 0.002 >>> (new + fy_vector)["Sm149"] 0.0009 >>> dict(new) == {"Xe135": 0.002, "I129": 0.001, "Sm149": 0.0003} True
