  • Method for operating a nuclear reactor and use of a specific fuel rod cladding alloy in order to reduce damage caused by pellet/cladding interaction
    Patent number: 9378850
    Abstract: A method for operating a nuclear reactor in order to produce electricity, such that the reactor is controlled so that, during a transient power occurrence for at least one of: a linear power density of the nuclear fuel rod remains lower than a limit linear power density, the limit linear power density being greater than 430 W/cm, and a variation of linear power density of the nuclear fuel rod remains lower than a limit variation, the limit variation being greater than 180 W/cm.
    Type: Grant
    Filed: June 1, 2004
    Date of Patent: June 28, 2016
    Assignee: AREVA NP
    Inventors: Christine Delafoy, Bruno Julien
  • 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.
