To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts aim to use fuels that must withstand unprecedented temperature and radiation extremes. In these advanced fuels, thermal energy transport under irradiation is directly related to reactor efficiency and safety, and is arguably one of the most important material properties.

The Center for Thermal Energy Transport under Irradiation (TETI) brings together an internationally recognized, multi-institutional team of experimentalists and computational materials theorists to develop a comprehensive, atom-to-mesoscale understanding of phonon and electron transport in advanced nuclear fuels. 

Highlight - Research on Suppressed Thermal Conductivity in Hyperstoichiometric Uranium Dioxide selected as 'Featured and Scilight' by Applied Physics Letters
