A new substep based burnup algorithm was implemented into Serpent 2 combining the previously implemented Stochastic Implicit Euler (SIE) and substep based burnup solutions. The implemented algorithm was shown to reproduce the gadolinium depletion better than the standard SIE algorithm in a miniassembly case while still producing stable results in a 3D coupled burnup calculation with fuel behavior feedback.
