To improve rates of nuclear power generation, ORNL has patented a way to increase the thermal conductivity of uranium oxide UO 2 fuel. This is achieved by adding high conductivity fibers to form a composite UO 2 fuel pellet. Essentially, the invention is a nuclear fuel pellet with a UO 2 matrix in which long fibers of a high conductivity material are randomly dispersed to act as heat conduits th…
