Finnish contribution to the CB4 burnup credit benchmark

  • 1. VTT Energy P.O.Box 1604, FIN-02044 VTT (Finland)

Description

The CB4 phase of the WWER burnup credit benchmark series studies the effect of flat and realistic axial burnup profiles on the multiplication factor of a conceptual WWER cask loaded with spent fuel. The benchmark was calculated at VTT Energy with MCNP4C, using mainly ENDF/B-V1 cross sections. According to the calculation results the effect of the axial homogenization on the keff estimate is complex. At low burnups the use of a axial profile overestimates keff but at high burnups the reverse is the case. Ignoring fission products leads to conservative keff and the effect of axial homogenization on the multiplication factor is similar to a reduction of the burnup (Authors)
