Power Peaking Factor usnig MCNP5

I model the core using MCNP 5, and I want to calculate the PPF for each assembly, and I want a way to do that.

The power peaking factor is simply the ratio of the local power density (in the fuel) to the average power density of all the fuel. It should be pretty obvious how to determine the average power density over the fuel volume. I've not had that experience in MCNP5 however.
