HI everyone,
The doc is a little unclear to me : What happen to neutron having inelastic scattering reaction ? Does the code continue the tracking of the neutron out ? Is it considered like a new neutron (new track) or the continuation of the same track as the input neutron. How is it taken into account in the kcoll estimator ?
When I compare my openmc results with my own Geant4 code, I have a slight difference (1%) on the keff. But in my G4 code, I simulate neutrons coming out of inelastic scattering reactions in the same batch with the same track. I have around 1% of produced inelastic neutrons in my test case so I assume the difference may come from there.
I use ENDF8 for for codes.
