Abstract
This article describes the implementation of a burnup
scheme with coupled fuel behavior feedback into the Monte
Carlo code Serpent 2. The new capabilities are applied to
estimate the effects of typical simplifications
concerning the fuel temperature distribution in the
burnup history part of group constant generation. A set
of group constants are generated for an assembly of the
EPR by executing the burnup history calculation with
either an assembly wide constant effective fuel
temperature or realistic pin-wise fuel temperature
distributions provided by a coupling to an external fuel
performance solver. The differences in nuclide
concentrations and generated group constants are
quantified and the benefits of using a separate effective
temperature for burnable absorber rods is investigated.
