Book Description
Sixty-day corrosion tests were performed in water at 290 deg C with unirradiated aluminum-uranium alloys containing 2 wt.% nickel and 1/2 wt.% iron, with several uranium contents from 15 wt.% to 53 wt.%. The maximum methi penetration rate (4 mils per year by extrapolation) of these alloys was no more than twice that of X8001 alumunum cladding alloy at the same temperature. Preliminary testing in water at 350 deg C indicated good corrosion resistance for this alloy system ap to a maximum of 80 wt.% uranium. (auth).

Book Description
In the search for a corrosion-resistant high-uraniumcontent alloy for use as core material in high-temperature-water-moderated reactors, the corrosion of binary and ternary U alloys was studied in water at 500 and 600 deg F. Alloys contaiiifng less than 40 wt, % Zr additions completely oxidized upon short exposure at 600 deg F, whereas 50 plus wt.% alloys exhibited relatively low corrosion rates. Alloys were sensitive to heat treatment and were most resistant in the quenched condition. The corrosion rates of Zr alloys were linear to slightly accelerated with respect to time. Alloys containing 40, 50, and 60 wt.% Zr were resistant to water at 500 deg F. Molybdenum additions (arc-melted alloys) in the range of 10 to 15 wt.% improved the resistance of U to 600 deg F water but did not result in corrosion-resistant alloys, probably because of inhomogeneity of the alloys studied. The addition of Mo, Nb, Th, Sn, and Ti to uranium--20 wt.% zirconium resulted in several promising alloys: uranium--20 zirconium--5 molybdenum and uranium--20 zirconium-10 niobium. Additions of up to 5 wt, % Mo did not improve the resistance of 40 and 50% Zr alloys to 600 deg F water. A uranium--30 zirconium--5.6 tantalum alloy also exhibited promising resistance to 600 deg F water. Other additions (2 and 5 at.%) which did not improve the resistance of uranium--30 wt.% zirconium were: Sb, Bi, Cc, Cr, Co, Fe, Pb, Ni, Nb, Si, Th, Ti, and W. (auth).

Book Description
Coupons of aluminum-uranium alloys at 10 and 18 weight percent were exposed to a saturated water vapor condition at 200 degrees C up to about 1500 hours and compared to previous results for aluminum 1100. The aluminum-uranium materials exhibited a range of initial corrosion rates and approached similar rates with the formation of a passive film of boehmite (Al2O3oH2O). The cast and extruded 10 percent uranium, having a primary aluminum-eutectic microstructure, was more corrosion resistant than the 18% cast and extruded. The initial corrosion rates of the aluminum-uranium materials were one to four times higher than that for aluminum 1100. It is postulated that a micro-galvanic coupling between the large UAl4 particles and the aluminum matrix has caused the variation. Sectioning the exposed specimens shows different characteristics of the oxide layers. In the case of the cast and extruded Al-10 percent U alloy, small uranium aluminide particles can be seen in the boehmite matrix and do not seem to be corroded. The oxide film of the Al-18 percent U alloy appears to have two distinct oxide layers. The outer layer has mass aggregates formed in the aluminum oxide matrix, while the inner layer contains UAl4 particles as in the case of Al-10 percent U.

Pages : 52
Book Description
Irradiation tests of an aluminum-alloy-clad aluminum -uranium alloy- fueled plate were discontinued due to cladding failure after a maximum burnup of 58%. Cause of the failure was local corrosion of the aluminum alloy. Swelling was observed which was attributed to the combination of high burnup and high fuel temperatures.
