摘要： A fuel rod position determination apparatus and a method are presented to enable efficient and accurate determination of the positions of the fuel rods in a fuel assembly in which it is not possible to insert a measuring instrument in a straight line through the fuel assembly. The apparatus first measures the positions of the peripheral fuel rods from the outside of the fuel assembly. This operation is continued by inserting sensors into the assembly through the spaces between the fuel rods so as to measure the profiles of the fuel rods. The positions of all the fuel rods including the interior fuel rods are determined on the basis of the profile data, the reference data formed by the peripheral fuel rods, and the known diameter data of the fuel rods.

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： In a pipe inner-surface inspecting apparatus, a body is inserted into an interior of the pipe and has an illuminator mounted at a forward end of the body for emitting light forwardly from the forward end of the body. A reflecting mirror in the form of a conical surface is so arranged as to face toward the forward end of the body with a space left between the reflecting mirror and the forward end of the body. The reflecting mirror diverges away from the forward end of the body, and reflects the light from the illuminator to illuminate the inner surface of the pipe thereby forming an image thereof. A concentrating unit is arranged at the forward end of the body for concentrating the image of the inner surface of the pipe, which is reflected by the reflecting mirror, to transmit the image to a rearward end of the body. A transparent glass is interposed between the reflecting mirror and the forward end of the body. The transparent glass has a surface in close contact with the reflecting mirror, which has a central region formed with a recess.

The pellet handling equipment is essentially composed of a first roller device, a second roller device, and a pellet supplying device. The first roller device is supported generally horizontal and rotatable about an axis thereof for a rotation in a predetermined direction. The second roller device is disposed parallel and adjacent to the first roller device, supported rotatable about an axis thereof for a rotation in a same direction with the first roller device. The second roller device is provided with a slot formed in a circumferential surface thereof and extending in the axial direction. The slot is capable of receiving each one of the pellets. The pellet supplying device intermittently supplies the pellets to the first and second roller device. Each of the intermittently supplied pellets is supported by the first and second roller device therebetween so that the axis of the pellet is parallel to the axes of the first and second roller device. Then, the pellet is rotated about an axis thereof as the first and second roller device rotate, trapped in the slot of the second roller device, and conveyed to the side opposite to the first roller device.
