uranium enriched to 89% was delivered to Los Alamos by July 1945. The entire 50 kg, along with some 50%-enriched, averaging out to about 85% enriched...

is used in enriching uranium for nuclear reactors and nuclear weapons. Uranium dioxide is converted with hydrofluoric acid (HF) to uranium tetrafluoride:...

It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared...
