Abstract

The effective bundle average fuel temperatures are required by the full core reactor physics code RFSP for local parameter calculations to account for the fuel temperature reactivity feedback.  For a fuel bundle at specific power and burnup, the neutron multiplication value calculated by the lattice physics code WIMS-AECL with a uniform fuel temperature should be the same as when fuel-pin temperature differences are considered.  Tahis methodology is illustrated by deriving the effective bundle average fuel temperature correlations for an example fuel design for RFSP calculations.
