摘要： In the automated production line manufacture of nuclear fuel bundle spacers, rod-supporting ferrules are cut from tubular stock, checked for length, laser cut to create predetermined features in the ferrule sidewall, formed with rod-centering stops in the ferrule sidewall, and checked for stop height dimensional accuracy. Pairs of ferrules are subassembled with a captive spring and assembled into a spacer assembly fixture together with other spacer parts. The fixtured spacer parts are conjoined by laser welding to create a structurally rigid spacer. The various production line operating stations are served by separate controllers linked to a central computer for production status reporting, parts traceability, and overall control purposes.

摘要： A quality assurance inspection system utilizes a plurality of ultrasonic transducers to probe an elongated tube for both dimensional and structural integrity. The transducers are pulsed in rapid succession, and echo signals are conducted over separate RF channels and through a multiplexor to a lesser number of detector signals channels, each including a discriminator. Inspection windows are opened in these discriminators to permit detection of echo signals and the generation of time mark signals for stopping a plurality of clocks which then register pulse-echo time intervals. These data are computer processed to provide tube dimension and flaw information.

摘要： To measure the dimensional characteristics of elongated flow channels for nuclear fuel rod assemblies at the manufacturing site, an upender is utilized to swing a flow channel from a horizontal loading orientation to an upright pre-measurement position and then to shift the flow channel laterally into a measurement position where it is engaged and held by reciprocatingly mounted upper and lower endplugs while its dimensional characteristics are acquired by a measurement carrige mounted for vertical scanning movement along the entire flow channel length.

摘要： Transport apparatus is disclosed for moving a stream of objects along a substantially continuous path between a source and a collection station and past a viewing station. A stream of successive, spatially separated objects is moved into end-to-end abutment to form successive stacks of objects. Each stack is spiraled past the viewing station with minimal vibration to expose the complete surface of each object to inspection. Subsequently each stack is rearranged into spatially separated objects which are rapidly sorted by diverting those objects from the continuous path which do not conform to predetermined criteria upon inspection. The transport apparatus achieves high throughput without compromising the accuracy of the inspection process.

摘要： In an automated first weld apparatus, a transporter conveys nuclear fuel cladding tubes successively to a welding station where a separate end plug is welded to an open end of each tube. Thereafter, the transporter indexes the tubes successsively through a cooldown station where the weld is cooled, to a reader station where a unique end plug serial number is read, and then to a succession of inspection stations where the internal and external weld characteristics are automatically examined. The resulting inspection data is correlated with the associated serial number for record purposes and tested against quality assurance standards pursuant to sorting the tubes into accepted and rejected lots.

摘要： Nuclear fuel cladding tube end plug welds are ultrasonically scanned to develop data indicative of weld thickness, weld penetration, and the existence and size of any included feature, such as pores. A computer analyzes the data to determine critical weld characteristics which are then tested against established quality assurance standards to see if the end plug weld is acceptable, all on an automated production line basis.
