Abstract
The scope of the present invention is the provision of a non-evaporable gettering ternary alloy particularly for the sorption of water and water vapor in nuclear reactor fuel elements. The ternary gettering alloy has a composition which when plotted on a ternary composition diagram in weight percent Zr, weight percent Ti and weight percent Fe lies within a polygon having as its corners the points defined by PA0 (a) 75% Zr--5% Ti--20% Fe PA0 (b) 60% Zr--5% Ti--35% Fe PA0 (c) 45% Zr--20% Ti--35% Fe PA0 (d) 75% Zr--20% Ti--5% Fe
