… This is calculated via flux-weighted averaging: \ \large \Sigma {homog} = \frac{\int {V} \Sigma \mathbf{r} \phi \mathbf{r} \, dV}{\int {V} \phi \mathbf{r} \, dV} = \frac{\text{Total Reaction Rate}}{\text{Total Flux}}\ where \ \Sigma \mathbf{r} \ represents the spatial macroscopic cross-section dist… …
