abstract = {Tritium (3H) must be replenished for strategic stockpile and fusion reactors.6Li-enriched $\gamma$-LiAlO2pellets have been used for3H production by thermal neutron irradiation. A fundamental study of3H and6Li diffusion processes in irradiated $\gamma$-LiAlO2pellets is needed to assess and predict the long-term material performance. This study focuses on identifying the trapping sites and diffusion pathways of1H (a surrogate for3H) and Li atoms in polycrystalline $\gamma$-LiAlO2pellets irradiated with both4He+and1H2+ions. A combination of STEM-EELS, Nano-SIMS and APT is employed for chemical imaging at nanoscale resolution. There is direct evidence for preferred Li diffusion pathways along grain boundaries. Isolated voids are identified as possible Li trapping sites in the irradiated $\gamma$-LiAlO2pellets. Possible lithium hydrides and/or hydrates are precipitated on the surface of the irradiated pellets. This study improves our understanding of H and Li diffusion processes and provides data for modelling and simulation to predict material performance during neutron irradiation of $\gamma$-LiAlO2pellets.},
