ABSTRACT:
A copper barrier type, nuclear fuel cladding is produced by forming an oxide layer on the inner wall surface of a tube of zirconium or zirconium alloy and then applying electroless copper plating to the oxide layer with a solution containing at least a copper salt, a complexing agent, a reducing agent, and 2,2'-dipyridyl, or further together with polyalkylene glycol as a plating solution. A good adhesiveness is obtained between the copper barrier layer and the oxide layer.
