ABSTRACT:
Nuclear fuel is canned in metal cans which have sealed closures to maintain the cans leak tight. Failure of the seal due to the chemical reaction of free hydrogen within the can is a problem which is alleviated by incorporating within the can a mass of a material which will be selectively attacked by hydrogen. Zirconium alloy is such a material and in the case of fuel canned in this alloy the hydrogen trap needs special shaping and positioning to ensure that it, rather than the can wall, is preferentially attacked by any hydrogen present.
