COMPOSITE NUCLEAR FUEL ELEMENT AND METHOD OF MANUFACTURE
Patent
·
OSTI ID:4106690
A process for forming reactor fuel elements is outlined in which an oxide powder of a fissionable material (usually UO@) is agglomerated with a resinous binder and a lubricant to form free-flowing granules which then are subjected to cold-pressing and sintering treatments to give compacts suitable for sealing in cans for reactor use. In a period between the pressing and sintering treatments, the compacts are heated to 500 to 9OO deg C in a CO/sub 2/ flow to remove the binder and lubricant. ln this way UO2/sup /mpacts of 92%>s theoretical density can be manufactured. The die for the pressing treatment is illustrated. (D.L.C.)
