Christiansen, D W; Karnesky, R A

A breeder reactor fuel element is described including a tubular clading hermetically sealed at each end by an end plug, one interior portion of the cladding defining a fuel space filled with a column of fissile material comprising a mixture of PO/sub 2/ and UO/sub 2/, and an upper and lower fertile material blanket. The blanket comprises UO/sub 2/ arranged axially in tandem with the fissile column within the cladding. The improvement comprises a cesium getter disposed at least at the upper end of the upper blanket. The getter includes a helical rolled substrate of stainless steel coated with silicon carbide material for collecting and isolating cesium migrating thereto and the stainless steel substrate having dimples formed therein for holding apart successive convolutions of the rolled substrate to permit a volume expansion of the getter.
