Dolphin’s cache laid out in a very concise manner a series of projects that purportedly composed Iran’s secret nuclear weapons program. They included the country’s ambitious plans to make its own nuclear fuel by mining uranium ore from a mine in southern Iran, then processing it to produce uranium concentrate (or “yellowcake”), and finally converting the yellowcake into uranium tetrafluoride and uranium hexafluoride gas. Uranium tetrafluoride can be used to make uranium metal, which can be used for nonweapons applications but also for bombs.
