The runtime settings are defined in the execution of MCNP in serial or in parallel mode. The installation of MCNP must support parallel calculations to run in parallel mode.

## Running the Model
Running the OpenMC executable is defined at the bottom of the monolithic python script, there are two options for you to choose from.

Add link to doc/content/microreactors/index.md. Then I'll do a review.

# Results

To fully characterize the underlying physics for STARTR, a comprehensive test suite was performed in both OpenMC and MCNP. Details on testing configurations and plots can be found in the STARTR companion milestone report for NRIC.
