In order to increase the safety of LWR fuel in severe accident scenarios, alternative cladding materials have been proposed to replace the currently used zirconium-based alloys. Of these materials, there is a particular focus on iron-chrome-aluminum (FeCrAl) alloys because they exhibit better high-temperature corrosion resistance than Zr-alloys.
Preliminary analysis has been performed through finite element simulation using the fuel performance code BISON-CASL. The analysis uses normal reactor operating conditions from a previous study on full-core reactivity equivalence for FeCrAl in order to explore itıs suitability as a replacement for Zr-alloy cladding. Fuel rod designs were made in order to minimize their neutronic penalty while maintaining the durability of current Zr-alloy cladding.
