  • Pencil comprising a stack of oxide nuclear fuel pellets
    Patent number: 9053830
    Abstract: The rod contains substantially cylindrical oxide nuclear fuel pellets based on enriched uranium oxide. The H/D ratio of the height over the diameter of the pellets lies in the range 0.4 to 0.6. The initial diametral clearance between the pellets and the cladding does not exceed 200 ?m.
    Type: Grant
    Filed: November 27, 2001
    Date of Patent: June 9, 2015
    Assignee: AREVA NP
    Inventors: Christine Delafoy, Pascal Deydier
  • Nuclear reactor green and sintered fuel pellets, corresponding fuel rod and fuel assembly
    Patent number: 9042507
    Abstract: A sintered fuel pellet for a water nuclear reactor fuel rod including a peripheral wall extending along a central axis and two end faces. At least one of the end faces includes at least a first chamfer extending from the peripheral wall towards the central axis with a first non-zero slope with respect to a plane perpendicular to the central axis and a second chamfer extending from the first chamfer towards the central axis with a second non-zero slope with respect to a plane perpendicular to the central axis, wherein the first slope is different from the second slope.
