Bismuth phosphate process

Bismuth-phosphate process was a process used to extract plutonium from used nuclear fuel taken from nuclear reactors.[1][2] This process was used to produce all the plutonium of the atomic bomb dropped on Nagasaki in 1945. In 1952 this process was replaced by the Redox[3][4] and PUREX processes.
