OSTI ID:4203279
A stainless steel PWR fuel element and its manufacture are described. A number of stainless steel rods containing UO/sub 2/ pellets are formed into a bundle to the ends of which flow nozzles are attached. A brazing fixture for this purpose is described. Short tubular ferrules are placed between the rods for spacing and rigidity Tubes are provided in some of the spaces for control rod movement. The structure offers mechanical integrity, corrosion resistance, adequate coolant flow, and satisfactory nuclear properties at an economy (T.R.H.)
