You might want to check the depletion notebook from openmc for transport-coupled depletion.

> <https://github.com/openmc-dev/openmc-notebooks/blob/develop/depletion.ipynb>

The details on python api for depletion calculation could be seen in [Depletion - Python API](https://docs.openmc.org/en/stable/pythonapi/deplete.html).  
I haven’t tried the transport independent depletion, but I think the [Transport Independent Depletion](https://docs.openmc.org/en/stable/usersguide/depletion.html#transport-independent-depletion) section has described this feature. So you can try it before setting up the integrator and do the `integrator.integrate()`.

Also, you might want to ask this kind of question on the [User support](https://openmc.discourse.group/c/user-support/5) section of the forum, which will catch more attention and show the related topics, such as this one [Negative atoms when using openmc.deplete.IndependentOperator](https://openmc.discourse.group/t/negative-atoms-when-using-openmc-deplete-independentoperator/3045) from Shimwell and others.
