  • Fuel element for a boiling water nuclear reactor
    Patent number: 6600800
    Abstract: In a boiling water fuel assembly, some of the fuel rods are shortened. It is necessary to establish a sufficiently high maximum power for transition to boiling. To optimize this power, spacers are at a constant distance at a bottom and are at a shorter distance at a top. The spacers belonging to upper group have turbulence-generating vanes which, however, do not project above the shortened fuel rods.
    Type: Grant

    Date of Patent: July 29, 2003
    Assignee: Framatome ANP GmbH
