A hollow skeletal bobbin is formed by two fixing rings, matched in dia. to the channel in the reactor fixed by spokes at each end of a hollow tubular centre rod, through which the tow cable is passed. The rings have a number of symmetrically spaced outer sliding pads and fixing holes for encapsulated samples of material to be irradiated which are mounted on the inner faces of the rings. Each ring has a peripheral slit over > 180 degrees and a portion of the outer half of the ring, carrying at least one pad, is made flexible passage of coolant in the channel is unimpeded. |
