Determination of hydrogen contamination of depleted uranium in a triple carbonate salt bath
Cast Depleted uranium (DU) ingots are placed in a stainless steel rack and submerged into a triple carbonate salt bath at 625/degree/C. After soaking for 1 to 2 hours (i.e., 1 hr. min., 2 hr. max.), the ingot and rack are removed from the salt bath and taken to the roll table where the ingot is removed from the rack and rolled. The salt residue on the rack begins to cool and, as it does absorbs moisture from the air which is the source of hydrogen. Another ingot is loaded into the rack, placed into the salt bath and the H/sub 2/ is liberated into the bath. When the H/sub 2/ concentration of the salt bath exceeds the H/sub 2/ concentration of the incoming ingots, diffusion of atomic H/sub 2/ into the DU ingot will occur. The objective of this study is to verify that the existing preheat soak times of 1 hour minimum and 2 hours maximum does not increase the H/sub 2/ content of a 2 inch thick DU ingot, soaking in a triple carbonate salt bath at 625/degree/C to above the specified maximum of 1 ppM. 2 refs., 7 figs., 1 tab.
