  • Method and apparatus for the zone-wise shuffling of nuclear reactor fuel elements
    Patent number: 4072559
    Abstract: For zone-wise shuffling of the fuel elements of a nuclear reactor core, single ones of the elements, one after another, are removed sequentially, and immediately upon the removal of each element it is tested for cladding defects, and if free therefrom, immediately inserted back in its new position in the reactor core, elements having cladding defects being eliminated. An apparatus for the rapid testing of each removed element is provided by a testing chamber containing water in which the removed element is immersed and allowed to remain for a short time, the water then being removed and tested for gamma activity to determine the element's cladding integrity. Other features are disclosed.
