Is there any class/mathod/variable to get all nuclides of depletion materials(include fission product),then I can pass nuclides list to results.get\_atoms().

The following should work:

```plaintext
results = openmc.deplete.Results('depletion_results.h5')
nuclides = list(results[0].index_nuc.keys())

```
