What was the code name for depleted uranium during the Manhattan Project?
During the Manhattan project, the ‘enriched uranium’ or 235 U, was given the codename oralloy, a shortened version of Oak Ridge alloy, after the location of the plants where the uranium was enriched. The term oralloy is still occasionally used to refer to enriched uranium. As for the codename for the depleted uranium, I couldn’t really find one,and one might think that the much less radioactive and therefore less dangerous version of the 235 U, the 238 U might not be important enough to recieve its own codename but prehapes a nickname in the form of ‘depleted uranium’.
