NOrmalizing Tally to get Flux value

All that is correct except for nu. While the units are indeed [neutrons/fission], the ‘nu-fission’ score doesn’t quite give you what you need. ‘nu-fission’ gives you the total fission neutron production, so you need to divide by the fission reaction rate in order to get the average number of neutrons per fission.

Best,
Paul
