A process for controlling the dissolution of a metal in an acid bath is described. The metal may comprise aluminum and the acid bath may contain a metal catalyst that causes the metal to dissolve. In order to control the rate of dissolution and/or the amount of gas evolved during the process, an iron source is added to the bath. In one embodiment, the process can be used to dissolve aluminum contained in spent fuel assemblies for recovering a nuclear fuel, such as uranium.

Process for dissolving aluminum for recovering nuclear fuel

A process for controlling the dissolution of a metal in an acid bath is described. The metal may comprise aluminum and the acid bath may contain a metal catalyst that causes the metal to dissolve. In order to control the rate of dissolution, the metal can be contacted with a cathodic member. In one embodiment, the process can be completely stopped even without removing the metal from the acid bath. The cathodic member provides anodic protection to the metal. In one embodiment, the cathodic member is made from a nickel-chromium-based alloy.
