How can you use MCNP to do time-dependent reactor calculations?

The only thing I know how on the basis of nuclear reactor design is how to run kcode in MCNP and see if my theoretical reactor is critical. How would I be able to calculate how the fuel is burning in my reactor over some period of time, and change my core composition accordingly?

There are two options. You can use MCNPX which has a depletion mode built into it, or you can use ORIGIN (part of the SCALE code package) to do depletion and then couple the results to MCNP (I believe there are codes which do the coupling automatically).
