Graphite flakes/UO2 fuel pellets with excellent thermal conductivity in radial direction

•Graphite flakes were used to improve the radial thermal conductivity of UO2.•Graphite flakes/UO2 presented highly-oriented structure and well-bonded interface.•The radial thermal conductivity of graphite flakes/UO2 was greatly improved by ~200%. In order to increase the radial thermal conductivity...
