What was the code name for uranium during World War II?

Senior Moments

There are lots of code names relating in some way to Uranium in the US, such as Manhattan. In the Europe, there was a Maud Committee. When Denmark was occupied by the Germans, Niels Bohr sent a telegram to Frisch, who had worked in Bohr’s Copenhagen laboratory, asking him at the end of the messageto "tell Cockcroft and Maud Ray Kent." Maud Ray Kent was assumed to be a cryptic reference to radium or possibly uranium disintegration, and MAUD was chosen as a code name for the uranium committee. Only after the war was Maud Ray identified as a former governess to Bohr’s children who was then living in the county of Kent. I am having trouble locating a code name just for the uranium but the three bombs were known as Gadget (the test bomb), Little Boy and Fat Man. "Basilisk" was used for uranium deuteride implosion. Missed out 'Trinity" from the three given previously although according to http://hypertextbook.com/physics/modern/weapons/ only Little Boy was Uranium fission as the others were plutonium.
