Hi there,
I’m trying to generate MGXS for diffusion analysis, and non-negligible (n,xn) reaction exists in my case.
From what I understand reffering Different k-eff in RESULTS and calculation, neutron multiplication should be accounted for scattering to reproduce the keff value using diffusion code.
So I have used nu-scatter matrix and calculated removal Xs as [total Xs - in group nu-scatter Xs], but I’m still learning theory in OpenMC and not confident about this.
Could you tell whether the method is right or other should be used?
Appreciate for your kindness!
