Physics - Nuclear fission Fission is where the parts of the atom dissassociate: radiation has different types, alpha, beta and gama. As things in nature degenerate such as carbon 14 to Nitrogen with Beta emission. That is a form of fission-although it happens over verrrrrry long periods of time. It happens with certain unstable isotopes and very large atoms: hence elements on the bottom of the Periodic Table and the lantanides and the actinides contain a lot of these unstable (radioactive) elements. (it is also happening on the sun constantly-every minute of every day. Fusion also happens on the sun. (fusion is where parts of the atom associate or gather). Biology - Binary fission Fission is the asexual reproduction of prokaryotic cells. Cells copy their DNA then grow in size beofre pinching off and creating two identical cells. It occurs every where you find bacteria, which really means everywhere on Earth from the Arctic/top of mount Everest to the deepest hydrothermal vents in the ocean.

∙ 14y agoNuclear fusion occurs in the stars. Nuclear fission as far as is known does not occur anywhere on earth, though there is evidence it did in a few places millions of years ago when there was more U-235. In the rest of the universe, who knows?

I don't know of fission occurring naturally anywhere, but there is evidence it once did in a few places on earth a long time ago. At that time there would have been more U-235 which has now reduced by decay. It may occur elsewhere in the universe in planets like earth, but we have no way of knowing this.
Natural nuclear fission: Oklo - please see the related link, below

∙ 13y agoYes, all isotopes of uranium can undergo fission spontaneously, and naturally, as can the isotopes of plutonium that naturally exist in trace quantities. It is rare, and all these natural isotopes more commonly decay by alpha emission. There is a description of this at the related question listed below.
Wiki User
∙ 13y agoYes. Radioactive elements are doing fission. I would not describe alpha, beta, or gamma radioactivity as fission, however uranium 235 found as a small percentage in natural uranium, does undergo spontaneous fission to a small extent. This means that in a nuclear reactor even when shutdown there are some neutrons being formed all the time, so that as criticality is approached these start to multiply. There is no need for an artificial neutron source to be loaded, though one usually is, to provide some neutron flux indication when shutdown

Where does nuclear fusion occur in a nuclear plant?
No place, we have not yet determined how to make a fusion reactor. Only fusion bombs.
Does size help nuclear fusion occur?
Yes, but on earth we are limited in size
Where does thermonuclear fusion mainly occur?
The only place in the universe where nuclear fusion can occur on its own is in the interior of stars. After closely observing nature, and adapting its laws to fulfill human requirements, our advanced civilization has succeeded in creating nuclear fusion at will, on a small scale. Unfortunately, the only useful application successfully developed so far with our superior intellect is the construction of nuclear bombs and weapons.
Where in the universe does fusion occur naturally?
Nuclear fusion is the process that powers stars, such as our sun.
What is nuclear fusion on the sun and where does it occur?
nuclear fusion is when 2 hydryon atoms combine or FUSE together. when this happens the neculous combine therefore causing nuclear fussion which releaces masses of heat and light enegry that radiates to earth
When does nuclear fusion occur?
nuclear fusion is not a natural occurrence, it is when two atoms are fused together
Where does nuclear fusion occur in a nuclear plant?
No place, we have not yet determined how to make a fusion reactor. Only fusion bombs.
Where does nuclear fusion occur in any star?
in the djfafkjkvn
Where does most nuclear fusion occur in your solar system?
Sun
Where does nuclear fusion occur and why?
In the cores of stars and hydrogen bombs.
Why does nuclear fusion not occur on earth?
Because the conditions of temperature and pressure that occur in stars do not occur on earth
Fusion reactions on the sun?
yes nuclear fusion does occur on the sun, creating intense heat and light
What layer of the sun does nuclear fusion occur?
It has to be at hundreds of millions of degrees kelvin, before a fusion reaction between deuterium and tritium will start
It takes an extremely high temperature for nuclear to occur inside the sun?
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.
Transmutation does not occur in which of these nuclear processes?
Transitions between various stages of electron excitement.
What is naturalization reaction?
Natural nuclear fusion reactions occur in all stars
Does size help nuclear fusion occur?
Yes, but on earth we are limited in size
