Abstract
Gen IV nuclear reactors need materials that can withstand harsher environments than in current reactors. The Mn+1AXn (MAX) phases are a group of layered machinable ternary compounds, where M is an early transition metal, A is a group 13 to 16 element, and X is C and/or N. These compounds possess mechanical properties atypical for ceramics. Data about their irradiated properties are required to fully realize their potential. Research is thus ongoing to characterize their irradiated properties. The pre-irradiated characterization, as well as neutron activation of several MAX compounds exposed to fast and thermal spectra will be presented. The specific activities of Ti3SiC2, Ti3AlC2 and Ti2AlC were similar to SiC and three orders of magnitude less than Alloy 617 for three activation times in both fast and thermal spectra. Like SiC, the main radioisotopes, after a decay period of 10 years are tritium and C14.
