摘要： An apparatus is presented for drying wet ground fuel pellets for nuclear reactors, inspecting the surface quality of the pellets, and loading the inspected pellets on a tray for storage. The pellets are discharged from a wet grinder, and are charged one at a time into pellet pockets formed at the periphery of a rotation disc, with the pellet axis aligned in the direction of transport. The rotation disc changes the transport direction from an axial direction to a radial direction, at right angle to the pellet axis. The rotation disc is provided with a gas circulation device, which delivers a flow of air from in-ports to edge surfaces of the pellets and discharges the air from out-ports. The direction of the air flow is alternated so that both end surfaces of the pellets will be dried completely. The underside of the pellets is also dried by an air flow directed to the pellets from gas outflow port disposed at the bottom region of the pellet pocket. The end surfaces and the side surface of each dried pellet are inspected in the pellet inspection section by image processing techniques, and the machine-inspected pellets are further examined visually in the visual confirmation section. The inspected pellets are loaded onto a tray, and are stored in the tray storage rack.
摘要翻译：提出了一种用于干燥核反应堆的湿磨料燃料颗粒的装置，检查颗粒的表面质量，以及将检查的颗粒装载在托盘上用于储存。将颗粒从湿式研磨机排出，并一次一个地填充到形成在旋转盘周边的颗粒袋中，其中颗粒轴线在输送方向上对齐。旋转盘将输送方向从轴向改变为与丸粒轴线成直角的径向方向。旋转盘设置有气体循环装置，该气体循环装置将空气流从颗粒的端口传送到边缘表面，并从出口排出空气。空气流动的方向是交替的，使得颗粒的两个端面将被完全干燥。颗粒的下侧还通过从设置在颗粒袋的底部区域的气体流出口引导到颗粒的气流干燥。通过图像处理技术在颗粒检查部中检查每个干燥颗粒的端面和侧表面，并且在视觉确认部分中进一步检查机器检查的颗粒。被检查的颗粒被装载到托盘上，并被存储在托盘存放架中。

摘要： A method and apparatus of sensing obstructions in a tubular nuclear fuel rod or the like is disclosed. A nozzle is positioned to engage one end of the fuel rod in an air tight sealed relationship. A first gas flows through the nozzle and then into and through the fuel rod. The pressure is sensed and compared with a standardized pressure to determine any excess back pressure in the nozzle indicating an obstruction present therein.

The workstation defines a fuel rod feed path extending between the carrousel and the magazine and is adapted to receive successively one at a time along the feed path at its upstream end fuel rods from selected ones of the carrousel gondolas. The workstation includes an optical scanning and reading unit located along the feed path for verifying the identity of the fuel rods successively one at a time and a fuel rod feeding mechanism for successively feeding one at a time along the feed path the verified fuel rods into selected ones of the slots in the magazine. The magazine holder and indexing mechanism movably supports the magazine and is actuatable for moving the magazine along X-Y axes to successively align one at a time selected one of its slots with the feed path for loading in the magazine the successive fuel rods in a desired enrichment pattern.

摘要： Pellet trays bearing rows of fuel pellets of known enrichment concentrations are retrieved from selected storage elevators and successively conveyed to a zone makeup machine. Parallel rows of pellets are raked from each tray and advanced over a longitudinally elongated, grooved loading surface into abutment with a selectively longitudinally positioned stop. A zone makeup carriage makes up the pellet rows to a prescribed, common zone length, which are then weighted and advanced in parallel by a vibratory loader into a plurality of cladding tubes arranged in parallel loading positions by tube handling apparatus. Overall operation is coordinated by a system controller to concurrently load the cladding tubes with multiple pellet zones of varying enrichments and lengths in automated fashion.

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： There is provided a nuclear fuel element having a zirconium alloy cladding tube with improved corrosion resistance. The cladding tube comprises a metallurgical gradient across the width of the tube wall wherein the tube has a more corrosion-resistant metallurgical condition at the outer circumference and a less corrosion-resistant metallurgical condition at the inner circumference. The metallurgical gradient can be generated by heating an outer circumferential portion of the tube to the high alpha or mixed alpha plus beta range while maintaining the inner surface at a lower temperature, followed by cooling of the tube.
