Abstract

After Fukushima’s nuclear disaster there has been a growing interest in introducing new safety concepts for future fission reactors. One approach is to develop Accident Tolerant Fuels (ATF) that can withstand the harsh environment within a fission reactor for at least 10 hours in a Loss-of-Coolant-Accident (LOCA). MAX phases are potential candidates for use in ATF as cladding. The system that has been targeted is Zrn+1AlCn. Zr offers compatibility with the zircaloy cladding, Al offers resistance to corrosion and oxidation, while C limits nuclear transmutation.This work studies the stabilization of Zrn+1AlCn MAX phases by partial substitutions in the quaternary systems (Zr,M´)n+1AlCn and Zrn+1(Al, A´)Cn with M´=Cr and A´=Si. Synthesis and sintering of MAX phases will be discussed as well as DFT calculations, indicating possible phase stability, will be shown.
