Method of making a fuel envelope with an alloy zirconium barrier |
| abstract |
Prodn. of a cladding tube, with an outer substrate, an intermediate Zr barrier layer and an inner alloyed Zr lining, involves (a) joining the outer surface of the barrier layer to the inner surface of the substrate; (b) joining the outer surface of the inner lining to the inner surface of the barrier layer; and (c) diffusion annealing to diffuse alloying elements from the lining into the barrier layer for forming a diffusion layer having an alloying element concn. which decreases from the inner surface of the barrier layer to a zero concn. location within the barrier layer. Also claimed is a similar process in which steps (a)-(c) are followed by (d) cold working with intermediate stress-relief or recrystallisation anneals; and (e) heating no more than the outer 33% of the outer substrate in the alpha & beta -phases or the beta -phase region and cooling to produce a distribution of fine pptes. in the outer region of the substrate. |
