:mod:`openmc.deplete` -- Depletion
|
|
----------------------------------
|
|
|
|
.. module:: openmc.deplete
|
|
|
|
Two functions are provided that implement different time-integration algorithms
|
|
for depletion calculations.

Each of these functions expects a "transport operator" to be passed. An operator
|
|
specific to OpenMC is available using the following class:

When running in parallel using `mpi4py <http://mpi4py.scipy.org>`_, the MPI
|
|
intercommunicator used can be changed by modifying the following module
|
|
variable. If it is not explicitly modified, it defaults to
|
|
``mpi4py.MPI.COMM_WORLD``.

Internal Classes and Functions
|
|
------------------------------
|
|
|
|
During a depletion calculation, the depletion chain, reaction rates, and number
|
|
densities are managed through a series of internal classes that are not normally
|
|
visible to a user. However, should you find yourself wondering about these
|
|
classes (e.g., if you want to know what decay modes or reactions are present in
|
|
a depletion chain), they are documented here. The following classes store data
|
|
for a depletion chain:
|
|
|
|
.. autosummary::
|
|
:toctree: generated
|
|
:nosignatures:
|

|
Chain
|
|
DecayTuple
|
|
Nuclide
|
|
ReactionTuple
|
|
|
|
The following classes are used during a depletion simulation and store auxiliary
|
|
data, such as number densities and reaction rates for each material.

Each of the integrator functions also relies on a number of "helper" functions
|
|
as follows:
