Fusion ocurs in the stars including our sun.
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.

What else can I help you with?
Does fission occur in the body?
No, fission does not naturally occur in the human body. Fission is a nuclear reaction that involves the splitting of atomic nuclei, which is not a process that happens in biological organisms.
What is repeated nuclear fission called?
Repeated nuclear fission is called a nuclear chain reaction. In this process, the fission of one nucleus releases neutrons, which can then induce fission in nearby nuclei, leading to a self-sustaining series of reactions. This principle is utilized in nuclear reactors and atomic bombs, where controlled or uncontrolled chain reactions can occur, respectively. The efficiency and safety of such reactions are critical in their applications.
Where does the reaction occur in nuclear fission?
Nuclear fission reactions typically occur in the core of a nuclear reactor. This is where the fissionable material, such as uranium-235, is bombarded with neutrons, causing the nuclei to split and release more neutrons and energy in a chain reaction.
Where is the nuclear energy produced in a nuclear reactor?
Nuclear energy is produced in the core of a nuclear reactor, where controlled nuclear fission reactions occur. These reactions release heat energy, which is then used to generate electricity through steam turbines.
Part of power plant where fission takes place?
The part of a power plant where fission takes place is called the nuclear reactor. This is where nuclear reactions, such as fission, occur to generate heat that is used to produce electricity. This heat is then used to heat water and produce steam that drives a turbine connected to a generator.
How are nuclear reactions that take place in the sun different from the nuclear reactions that take place in a nuclear reactor?
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)
Can fission occur after fusion?
No, fission and fusion are two distinct nuclear reactions. Fusion involves the joining of atomic nuclei to release energy, while fission involves the splitting of atomic nuclei. They are not directly connected processes, so fusion does not lead to fission.
Is fission process possible on earth?
About 3 billion years ago, when U235 was much more common, it did. Look up the Oklo natural reactors in Africa for an example. There were probably other sites too.Manmade nuclear power reactors.Manmade nuclear weapons.
The nucleus of an atom can store what kind of energy?
The nucleus of an atom can store potential energy, which is released when nuclear reactions occur, such as fission or fusion. This energy is harnessed in nuclear power plants or in nuclear weapons.
What part of the nuclear powerplant does the chain reaction occur?
The chain reaction in a nuclear power plant occurs in the reactor core, where nuclear fission reactions take place. Heat generated from these reactions is used to produce steam, which then drives turbines to generate electricity.
Which is generally not associated with nuclear reactions?
Weather patterns are generally not associated with nuclear reactions. Nuclear reactions involve processes that occur at the atomic nucleus level, often related to the release of energy through fission or fusion, whereas weather patterns are the result of complex interactions in Earth's atmosphere and are driven by factors such as temperature, pressure, and humidity.
What is fission temperature?
Fission temperature refers to the temperature at which nuclear fission reactions can occur. For uranium-235, which is commonly used in nuclear reactors, the optimal fission temperature is around 572°F (300°C). Controlling the fission temperature is crucial for maintaining the stability and efficiency of a nuclear power plant.
