초록 ▼

A method of manufacturing nuclear fuel elements which include fuel rods whose cladding tubes are provided with an internal liner layer to obtain PCT resistance in the nuclear fuel element involves carefully choosing parameters for heat treatment of the inner component even from the machining of an ingot of the inner component. The internal layer of zirconium or a zirconium alloy, suitable as inner layer in a PCI-resistant cladding, from the fabrication of an ingot of the inner component up to the completion of a cladding tube, including forging, rolling, extrusion, heat treatment and final heat treatment, is manufactured in such a way that the temperature in the inner component never exceeds the temperature when an incipient phase transformation to beta phase takes place.

대표청구항 ▼

A method of manufacturing a composite cladding tube of a nuclear fuel element which is resistant to pellet-clad interaction, said composite cladding tube comprising an inner portion formed from a first component selected from the group consisting of zirconium and a zirconium alloy and an outer portion formed from a second component selected from the group consisting of Zircaloy 2, Zircaloy 4 and Zr 2.5 Nb, said method comprising the steps of: (a) providing an ingot of said first component, (b) forging rolling, extruding, and heat treating said ingot of said first component to form an inner billet, (c) positioning said inner billet from step (b) within an outer machined billet formed from an ingot of said second component, (d) extruding said joined billets from step (c) to form a joined tube blank, and (e) machining said tube blank from step (d) to provide said composite cladding tube, (f) said steps (b)-(e) being conducted at a temperature below that which causes incipient beta-phase transformation within said first component.
