In every nuclear reactor that is operating
nuclear fission
Uranium is the only naturally occurring element used for nuclear fission in commercial nuclear reactors. It is typically found in two isotopes, uranium-235 and uranium-238, with uranium-235 being the primary isotope used for nuclear fission reactions.

yeah its occurring in Darfur

Fission in Uranium would take billions of years when its left to its own devices. Because of radioactive decay, it would either release alpha or beta radiation, or fission. The earth would have to be really old for that to maybe happen. Besides, Only less than 1% of Uranium is U-235, which is the only isotope of uranium that would fission, is found on earth.
Fission. Fusion has never been used on Earth, except for nuclear weapon tests.
The element most commonly used as a fuel in nuclear fission reactions is uranium-235. It is a naturally occurring isotope of uranium that can sustain a chain reaction under controlled conditions in nuclear reactors.
Theory of uniformitarianism.
I think it is constantly occurring, and has never stopped.
Nuclear fission happens spontaneously in nature. Uranium-235 does this, and is the only commonly occurring natural isotope that does. Nuclear fission can be induced by crashing a neutron into a fissionable atom. Some things other than Uranium-235 are fissionable, notably Uranium-238. Fission has been induced in various experiments. It happens in nuclear reactors and in nuclear bombs.
