Claim 1
Independent Claim
115 words
A METHOD OF FABRICATING A NUCLEAR REACTOR FUEL ELEMENT ASSEMBLY COMPRISING HOLDING A PLURALITY OF LONGITUDINALLY EXTENDING FLAT FUEL ELEMENTS IN SPACED PARALLEL RELATION TO EACH OTHER, HOLDING A SUBSTANTIALLY FLAT SIDE PLATE SO THAT CORRESPONDING ENDS OF SAID ELEMENTS ARE CONTIGUOUS TO ONE SIDE OF SAID PLATE, AND PASSING A WELDING MEANS ALONG THE OTHER SIDE OF SAID PLATE IN A DIRECTION TRANSVERSE TO THE DIRECTION OF THE LONGITUDINAL EXTENSION OF SAID ELEMENTS, THE SETTING AND SPEED OF TRAVEL OF SAID WELDING MEANS BEING SUCH AS TO CAUSE PENETRATION OF SAID SIDE PLATE WITH WELDS THAT BRIDGE THE GAP IN EACH CHANNEL BETWEEN ADJACENT FUEL ELEMENTS WITH A WELD THROUGH BUBBLE OF PREDETERMINED SIZE.
