  • Advantage and Disadvantages of Thorium ReactorsPros and

    Compared to the predominant reactor fuel uranium dioxide (UO 2) thorium dioxide (ThO 2) has a higher melting point higher thermal conductivity and lower coefficient of thermal expansion. In particular the thermal conductivity is important since it leads to a lower fuel pellets temperature.
