Bramblett, R L; Preskitt, C A

A nuclear fuel pin scanner system is described for inspecting nuclear fuel pins at a throughput rate to determine the uniformity and amount of fissile material contained in the fuel pin, comprising: a rotary irradiator having a source of activating radiation located centrally thereof, the irradiator having a plurality of circumferentially spaced positions thereabout for supporting fuel pins in radially spaced relation to the source of activating radiation; means for feeding and discharging the fuel pins singly into and from the irradiator at the throughput rate; means for rotating the irradiator and fuel pins contained therein about the source of activating radiation whereby each fuel pin is irradiated for an extended period of time relative to the throughput rate; and detector means downstream of the irradiator comprising an array of axially spaced radiation detectors for detecting radiation from segments, respectively, of each fuel pin during oscillatory movement of the fuel pin relative to the detector means to achieve an effective total scanning time for the pin equal to a detection period times the number of segments.
