The only example of nuclear fission in a naturally occurring material is of Uranium 235, which comprises 0.7 percent of natural uranium, the rest being Uranium 238 which is not fissile. To use U235 in a nuclear reactor it is usually enriched to about 4 percent first, though reactors have been designed to use natural uranium. These have to use graphite or heavy water as moderator, as normal water absorbs too many neutrons.
During reactor operation some of the U238 absorbs a neutron and becomes Plutonium 239 which is also fissile, so this contributes to a proportion of the reactor power which increases as the fuel is used and the U235 diminishes.

Nuclear fusion to nuclear fission?
Nuclear fusion is the phenomenon in which two lighter nuclei get fused to form heavier nucleus with the production of energy. Best example is SUN and hydrogen bomb. But nuclear fission of breaking heavier into lighter with the emission of energy. Example uranium-235. So atom bomb Nuclear fusion has clean energy but fission has hazard energy
What is the splitting of an atoms nucleus into two smaller nuclei is called?
nuclear fission
What is splitting of atomic nuclei?
FISSION. nobody on this website knows the answer..... SHAME
What is the process of the production of lighter nuclei from heavier nuclei called. Nuclear radiation nuclear force fusion or fission?
Nuclear fission
What are other information about nuclear fission?
nuclear fission is the process of splitting atoms.
What is an example of uncontrolled nuclear fission reaction?
Atomic fission bomb.
Where do you get nuclear fission?
You get nuclear fission in:nuclear fission reactorsatomic fission bombs
Is an example of nuclear fission?
An example of nuclear fission might be a nuclear weapon. In this device, sub-critical masses of fissionable material are driven together by conventional explosives. This "assembles" a critical mass, and a chain reaction will follow. That is a nuclear fission chain reaction. In another example, a nuclear reactor has its control rods pulled and achieves criticality. It is brought to operating temperature and generates heat to make steam and drive turbines. The reactor operates on the principle of nuclear fission.
Fission and fusion are example of what kind of energy?
Nuclear energy.
Is uranium 235 and a neutron producting barium 141 an example of nuclear fusion?
No. it is an example of nuclear fission (splitting of nucleus).

How is the sun an example of nuclear energy?
The sun's energy is produced by nuclear fusion (not fission) at the core of the sun.
