Abstract

This work examined the impact of substituting FeCrAl cladding on a single PWR fuel rod and a single fuel assembly within a full core environment of standard Zircaloy cladded fuel. The goal was to provide insight on a pin-by-pin level of the power peaking effects caused by heterogeneity in the lattice, as well as to investigate some of the key fuel performance parameters. The neutronic analyses herein reported were performed using CASMO-4/SIMULATE-3 models of a representative equilibrium PWR core with standard Westinghouse 17x17 assemblies, while the fuel performance analysis was performed using the BISON code with FeCrAl constitutive models currently under development at the University of Tennessee in collaboration with Oak Ridge National Laboratory.
