Hi,  
I have calculated the flux and fission rate of the core by following link :[https://nbviewer.org/github/openmc-dev/openmc-notebooks/blob/main/mg-mode-part-i.ipynb](https://nbviewer.org/github/openmc-dev/openmc-notebooks/blob/main/mg-mode-part-i.ipynb),but i don’t know how to convert flux distribution into power distribution .  
After the calculation of radial power distribution,I need to calculate the power peaking factor and the axial power distribution. Could you tell me how to finish the calculation?  
Thanks.
