Aug 06, 2019 · Unlike coal, which can be used in a power station without much processing, nuclear reactors cannot simply be fuelled with uranium ore. The nuclear fuel cycle begins when mined uranium ore is converted to yellowcake, which contains about 90% uranium oxides. This is the only step of the nuclear fuel cycle that already exists in Australia.
