Oxidation-resistant iron-chromium-aluminum (FeCrAl) steels have been proposed for application as cladding materials in light water reactor fuel rods with improved accident tolerance. Within the Coordinated Research Project ACTOF of the International Atomic Energy Agency (IAEA), a fuel performance modeling benchmark for FeCrAl cladding behavior was conducted. During this effort, calculations were performed with various fuel performance codes for a set of fuel rod problems with FeCrAl steel as cladding material, and results were compared to each other. Comparisons to Zircaloy-4 cladding behavior under the same conditions were also included. Considered cases covered both normal operating and loss of coolant conditions. Participating organizations were INL (BISON code), NINE (TRANSURANUS), JAEA in cooperation with Waseda University (FEMAXI-7), University of São Paulo (FRAPCON) and CNEA (BACO). Results of the benchmark are presented and discussed in this contribution.
