The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. In a free-electron liquid, the electronic part of the thermal conductivity κ 0 and the electrical conductivity σ 0 are related by the Wiedmann-Franz law L = κ 0/σ 0T, where L is the Lorenz number. J. Millat, M. Ross, W. A. Wakeham, and M. Zalaf, The thermal conductivity of neon, methane and tetrafluoromethane, Physica, 148b, 124–152 (1988). This formula now clearly shows that the thermal conductivity of ideal gases is not dependent on particle density and thus not on pressure. Most of PWRs use the uranium fuel, which is in the form of uranium dioxide.Uranium dioxide is a black semiconducting solid with very low thermal conductivity.On the other hand the uranium dioxide has very high melting point and has well known behavior.The UO2 is pressed into pellets, these pellets are then sintered into the solid. unit thickness and cross-sectional area per unit time, under the The thermal conductivity of uranium dioxide is very low when compared with metal uranium, uranium nitride, uranium carbide and zirconium cladding material.
