The thermal conductivity of condensed matter can be reduced through the introduction of isotopic disorder as the different isotopes act as mass defects that scatter phonons responsible for the transfer of heat energy. Here we investigate, using classical molecular dynamic simulations, the magnitude of this effect in the ceramic oxide Li2O, which will be artificially enriched with Li-6 to improve tritium breeding potential in a future fusion reactor. The results show that while the isotope effect will be important at lower temperatures it has little influence at the expected operating temperatures of the breeder blanket. (c) 2012 Elsevier B.V.
