文摘
- •
Neutronic impact of protecting LWR cladding with ceramic coatings or replacing zircaloy with alternative materials is evaluated.
- •
Adding thin ceramic coatings, the corresponding reactivity penalties are small and proportional to the coating thickness.
- •
Substituting FeCrAl, TZM, and Alloy 33 for zirconium-alloy cladding generates considerably shorter fuel cycles.
- •
SiC cladding can be up to ∼25% thicker than zirconium-alloy cladding with no impact on cycle length.
