Patent
·
OSTI ID:4204381
A tubular fuel element covered inside and out by a unitary covering tube originally about twice its length and of small enough diameter to fit snugly inside the fuel tube is described. The covering tube is then reentrantly folded back by a pressure-die mechanism over both ends of the fuel tube and againsts outside until the folded back ends of the covering tube meet where they are welded in a single seam running circumferentially around the middle of the resulting assembly.
