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 Zr<sub>n+1</sub>AlC<sub>n</sub>. 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 Zr<sub>n+1</sub>AlC<sub>n</sub> MAX phases by partial substitutions in the quaternary systems (Zr,M´)<sub>n+1</sub>AlC<sub>n</sub> and Zr<sub>n+1</sub>(Al, A´)C<sub>n</sub> 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.
