ZIRCONIUM CLADDING OF URANIUM

PDF Version Also Available for Download.

Description

Under proper conditions of vacuum and mold preheat, a sound ductile alloy bond can be achieved by casting molten uranium into zirconium and Zircaloy- 2 molds. Investigations indicate that a process for production of zirconium of Zircaloy-2 clad fuel elements can be developed by casting directly into preformed shells. Employment of cast bonding techniques appears to be a simple and practical method for assembling extrusion billets. It also appears that coextrusion of cast bonded normal uranium billets produces a clad rod exhibiting a rather uniform cladding thickness and map permit greater freedom in selection of extrusion conditions to produce a ... continued below

Employment of cast bonding techniques appears to be a simple and practical method for assembling extrusion billets. It also appears that coextrusion of cast bonded normal uranium billets produces a clad rod exhibiting a rather uniform cladding thickness and map permit greater freedom in selection of extrusion conditions to produce a clad and bonded geometry. Forming of cast bond ingots in diamond-round or oval-round sequences falled to produce a clad rod with uniform jacket thickness. subsequent forming operations failed to rectify nonuniformities in jacket thicknesses once they had occurred.
