Where does fission happen in universe?
There is evidence that it did occur on earth some two billion years ago, in a few places with high levels of uranium present. As far as the rest of the Universe, we just don't know.
How become uranium to krypton and barium?
Uranium does not naturally turn into krypton and barium. These elements are created through nuclear reactions, typically in a nuclear reactor or during nuclear fission processes. During these reactions, uranium atoms can split into smaller atoms like krypton and barium, releasing energy in the process.
What products are given off during a typical nuclear fission reaction?
During a nuclear fission reaction, products such as two or more lighter nuclei, neutrons, gamma rays, and energy are given off. These products can vary depending on the specific isotopes involved in the reaction.
What other isotope besides tellurium-137 is produced by nuclear fusion of uranium-235?
Besides tellurium-137, another isotope produced by the nuclear fusion of uranium-235 is xenon-135. During the fission process, uranium-235 can absorb neutrons and undergo various decay pathways, leading to the formation of different isotopes, including xenon and tellurium isotopes. These fission products play significant roles in nuclear reactions and the management of nuclear waste.
What are fission by-products?
Fission by-products are the radioactive materials produced during the splitting of atomic nuclei in nuclear reactions. These by-products can vary but typically include isotopes of elements such as cesium, strontium, iodine, and xenon. Proper handling and disposal of fission by-products are essential to prevent environmental contamination and health risks.

How does fission create radioactive waste?
During fission, atoms split into smaller fragments, releasing energy and neutrons. Some of these fragments are radioactive isotopes, which emit radiation and decay over time, creating radioactive waste.

What are the fission products in the figure?
The fission products shown in the figure are typically smaller nuclei formed during the nuclear fission of uranium or plutonium. These products can include isotopes of various elements such as cesium, iodine, strontium, xenon, and barium. They are radioactive and can pose health and environmental risks if not properly contained.
How does radioactive materials used to produce nuclear energy?
Nuclear energy is produced by fission of new fuel, which is only very slightly radioactive to start with (it is safe to handle unprotected). It becomes radioactive during the reactor's operation, and at the end of life the radioactivity of the fuel contributes some 5% or so of the output heat, the rest is due to fission directly. There are some uses for radioactive isotopes to produce electricity directly but these are only used in satellites for small instrument type supplies.
What are fission by-products?
Fission by-products are the radioactive materials produced during the splitting of atomic nuclei in nuclear reactions. These by-products can vary but typically include isotopes of elements such as cesium, strontium, iodine, and xenon. Proper handling and disposal of fission by-products are essential to prevent environmental contamination and health risks.
Why are the fragments of fission radioactive?
Fission fragments are radioactive because they contain unstable isotopes produced during the nuclear fission process. These isotopes undergo radioactive decay, emitting radiation in the form of alpha, beta, or gamma particles to achieve a more stable state.
What causes a splitting nucleus?
The capture of a neutron can split a nucleus - but only for certain isotopes like U-235 and Pu-239. Two naturally occurring isotopes undergo spontaneous fission, meaning the nucleus splits without neutron capture. These are 235U and 238U. A few other isotopes undergo spontaneous fission, but these are produced by an earlier neutron capture. Spontaneous fission is the result of quantum tunnelling, which is rather difficult to explain. There are related links below.
Is energy released during fission but absorbed during fusion?
Energy is released during fusion and fission.
What happens in a nuclear reactor to create electricity?
In a nuclear reactor, the controlled splitting of atoms (nuclear fission) generates heat, which is used to produce steam from water. The steam then drives turbines that are connected to generators, producing electricity. The process essentially harnesses the heat energy released during nuclear fission to produce electricity.
What is fission product?
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
