Design and performance of shroud-tubes in sodium-bonded advanced fuel elements

OSTI ID:7302680
Shroud tubes were conceived as a means of preventing the rearrangement and wedging of broken fuel pieces in sodium-bonded advanced-fuel elements. The specific design of a thin-walled tube with slots that fits closely around the fuel was arrived at by consideration of a number of competing mechanical and heat-transfer requirements. Postirradiation examination results obtained to date indicate that shroud tubes are meeting the design requirement of retaining fuel fragments. No cladding failures have been observed in any sodium-bonded element using a shroud tube. The excellent irradiation performance of sodium-bonded elements with shroud tubes as compared to similar elements without shroud tubes demonstrates the utility of the shroud-tube concept.
