摘要： An automated fuel rod production system includes a radioactive powder fabrication and processing stage, a pellet fabrication stage, a pellet processing stage, a tube preparation stage and a fuel rod fabrication and inspection stage, all of which provide a continuous (paced) mode of operation from the conversion of a radioactive gas to powder, through the fabrication of the powder into pellets, to completion of the assembly of the fuel rods. Extra capacity is designed into the system at critical points in the powder processing and pellet fabrication and processing stages to facilitate the continuous, paced mode of operation.

摘要： A system for processing both ends of tubes, such a nuclear fuel rod cladding tubes. A conveyor, adjustable for different length tubing, supports and transversely moves the tubes to tube-end-processing sites. The conveyor is spaced up at the first-tube-end-processing sites to create first access areas. First-tube-end-processing machines have bases with a portion placed underneath the conveyor in these first access areas. The first machines have tube-end-processing modules movably mounted on the bases to accommodate different length tubing. The system also includes second-tube-end-processing machines having tube-end-process modules positioned at the second-tube-end-processing sites. The modules process the tube ends with such operations as deburring, attaching fittings for flush etching the tubes, etc. Preferably, the modules are aligned for the system to process both ends of a tube simultaneously.

摘要： Method for removing fuel pellets from a nuclear fuel element without damaging the fuel pellets or fuel element sheath so that both may be reused. The method comprises holding the fuel element while a high pressure stream internally pressurizes the fuel element to expand the fuel element sheath away from the fuel pellets therein so that the fuel pellets may be easily removed.

摘要： An ultrasonic tube inspection system capable of rapid changeover for inspecting tubes of different diameter sizes includes a serial arrangement of multiple separate inspection stations. One inspection station is used to inspect for tube dimensions irrespective of the tube diameter size. The other inspection stations are used to inspect for flaws and are employed for different ones of the tube diameter sizes to be inspected. A set of ultrasonic transducer assemblies is supported at each inspection station. The transducer assemblies at the flaw inspection stations are in proper orientations corresponding to the diameter sizes of the particular tubes to be inspected at the respective inspection stations without the need for readjustment. The inspection stations contain quantities of liquid for coupling ultrasonic energy between the ultrasonic transducer assemblies and the tube passing through the inspection stations. Liquid level control stations are disposed at opposite ends of the serial arrangement of inspection stations and are connected in flow communication with the inspection stations for controlling liquid level in the inspection stations. Tube drive are disposed adjacent the liquid level control stations and are operable to drive the tubes through the control and inspection stations such that the tubes are aligned along a common centerline irrespective of which tube diameter size is being inspected.

摘要： Systems for, within a sealed environment, determining the bulk density of radioactive nuclear fuel particles flowing in a process stream. A carrier having a known weight and a channel of known volume is selectively shuttled between the flowing particles and a weigh cell. Thus, from the weight of a known volumetric sample, the bulk density is determined. The carrier and selected portions of the cell and carrier transporter are enclosed within a sealed structure to contain the radioactive material within a controlled environment. Subsequent to density determination, the particle sample is dumped, preferably back into the flowing stream, by structure which rotates the carrier or opens a door at the bottom of the channel. The systems also provide for sealing of the housing at various positions of the carrier.

摘要： A dashpot in a control rod guide thimble for a nuclear fuel assembly includes a lower tubular portion of an elongated main tube of the guide thimble, an auxiliary hollow tube inserted in the lower portion of the main tube, and an end plug attached to a lower end portion of the auxiliary tube. The auxiliary tube has an outside diameter slightly less than an inside diameter of the main tube to permit a close fitting relationship between an exterior surface of the auxiliary tube and an interior surface of the main tube lower portion. The auxiliary tube also has an upper end portion with an inside surface portion in axial cross-section flaring upwardly and outwardly to provide a tapered transition extending between and connecting an interior surface of the auxiliary tube with the exterior surface thereof.

摘要： An apparatus for processing the interiors of elongated hollow tubes having open opposite ends, such as by acid etching, water rinsing, steam cleaning or air drying the tube interiors, includes a pair of tube clamping mechanism being operable between tube clamping and unclamping conditions. The clamping mechanisms when in their clamping conditions support the tubes in stationary side-by-side spaced positions for processing and at locations on the tubes displaced inwardly from their opposite ends. The apparatus also has a pair of fluid supply manifolds each being displacable between disengaged and engaged positions with respect to the open opposite tube ends and having nozzles for engaging the respective tube ends to seal off the interior of the tube from the external atmosphere when the manifolds are in their engaged positions. A selector valve is mounted in each manifold and is selectively operable to provide communication between at least one source of pressurized processing fluid and the tube interior through the respective manifold. A pair of pneumatic actuator mechanisms are used for displacing the manifolds between their disengaged and engaged positions. The apparatus also has a frame and the clamping mechanisms, manifolds and actuator mechanisms are mounted thereon for movement toward and away from one another to place them at different distances from one another corresponding to the different lengths of the tube being processed.

摘要： An improved tube drive apparatus includes drive units disposed in respective orientations angularly displaced about and radially extending from a longitudinal centerline of a tube to be driven by the drive units and a drive train drivingly coupling a motor to the drive units for transmitting driving motion thereto. Each drive unit includes an endless flexible drive belt, a pair of spaced rotatable members entraining the drive belt such that an end of the belt drivingly engages the tube for transmitting driving motion thereto. One rotatable member is drivingly coupled to the drive train and the other rotatable member is angularly adjustable relative to the one rotatable member and the centerline of the tube such that runs of the belt can be changed between generally parallel and criss-cross orientations for varying the motion of the tube produced by engagement of the belt from solely axial rotation to solely longitudinal movement and any combintion of the two motions therebetween. A ratchet screw is provided for adjusting the angular relationship between the two rotatable members and thereby the degree of twist in the drive belt and the direction of motion of the tube.
