Why is there unlike fission fuel no limit to the amount of fusion fuel that can be safely stored in one locality?

ð Fusion doesn't happen unless we got a lot of energy to drive nuclei together otherwise. It can't get out just by thermal neutrons from a spontaneous reaction because fission fuel has unstable nuclei and spontaneously decays so often. If there's enough of it together it can start a chain reaction when the high energy particles from the decay bombard other nuclei and produce more high energy particles. Fusion fuel has typically has stable nuclei and doesn't spontaneously decay. Also, a nucleus that is lighter than iron, which defines fusion fuel, doesn't release energy when broken apart. So even if a nucleus is hit with a high energy particle and breaks apart, no energy is released and the reaction kind of fizzles out.

What isdifference nuclear fission and nuclear fission?
The difference between Fusion and Fission is that Fission is easier to do and produces more energy than fusion reactions. However fission can be dangerous and is used in Nuclear reactors. Fusion however is safer and produces less energy but safely. It is quite difficult to cause a Fusion reaction however.
If scientists can utilize nuclear fission to create energy such as in nuclear electric power plants why can't they use nuclear fusion?
Because nothing to safely hold the process in has been developed yet.
How are nuclear fission and nuclear fusion are the same?
They are similar only in that they are nuclear reactions. In nuclear fission involves the splitting of an atomic nucleus, whereas nuclear fusion involves the joining together of atomic nuclei.
What is preferred fusion or fission?
fission is splitting of heavier and unstable nucleus into lighter nucleus'. in the fission process mass of the parent nucleus is more than the sum of the mass of the daughter nuclei,so this mass defect is converted into energy according to Einstein's formula E=mc^2,hence giving off a huge energy.uncontrolled emission of this energy causes explosion of huge magnitude,as in atom bombs or the chernobyl explosion in russia.however this fission energy can be controlled in a nuclear reactor using moderator and graphite rod with suitable techniques, giving rise to a clean and efficient source of energy.this is applieid in the nuclear plants.fusion is fusing of two lighter nuclei in presence of huge energy to produce a heavier nuclei.this process in turns releases even more energy which is quite large compared to even fission process!!!however this fusion cannot be controlled in a suitable environment as in fission,so it's only technical manifestation has been observed iin hydrogen bombs,which are much more powerful than atom bombs.some experiments confirm occurence of fusion at cryogenic temperatures,known as cold fusion,but researches are still going oon in that field.so we may conclude from a humanitarian and apllicative point of view,fission is better and more useful than fusion.Point of factThe explosion at the Chernobyl power plant was not thermonuclear in its nature. Had it been there would be nothing whatsoever remaining of the surrounding buildings. This is not the case. It was, however, a very large explosion. It decimated one side of the building that housed it and released vast amounts of radioactive material into the atmosphere. It should be noted that Chernobyl was, at the time an experimental type of reactor that was based on a tried & tested British design which had been safely operating for several years. It is believed that the lack of suitably trained operations staff led to critical oversights in the monitoring of the reactor, and ultimately the explosion. There are fission reactors based on the same design that are still functioning safely and efficiently today. Which Is Better?Fission is better because fusion is so powerful that it would release a massive amount of energy that could destroy the entire planet.
What are the risks of nuclear fusion?
The main disadvantage of fusion is that no scientists have been able to contain a fusion reaction long enough for there to be a net energy gain, but nuclear fission is already producing 11% of the worlds energy needs.The atomic bomb.
Why must products of nuclear fission be stored safely?
Because they are mostly very radioactive and many have long halflives
How long do a cilia cell live?
Since ciliates tend to reproduce by fission, you can safely argue that they can live forever.
What is nuclear power plant decommissioning?
It is safely disposing of the bits of a burned out power station. (As nuclear fission gives off neutrons, anything near a nuclear fission reaction itself becomes radioactive over time, so it is a big job to take down a power station safely)
What are the waste products produced by nuclear fusion?
These are the fission products, they are lighter elements formed by the splitting of uranium 235 nuclei into two pieces. The process produces a range of pair combinations, not always the same pair, but there are two peaks of resulting atomic number nuclei. Many of the fission products are intensely radioactive, and so dangerous, but they are contained within the fuel and its zircaloy sheath, and so long as this is intact they can be controlled safely. It is only if the fuel sheath is damaged that the active products can escape, but even then they will not leak to atmosphere unless there is also a leak in the primary reactor circuit. See link below
Can the waste products of nuclear fission be safely disposed in rivers and streams?
No, certainly not, they must be kept in a well shielded repository for centuries.
Is fission good for the environment?
Nuclear energy via fission reactors is neutral as far as the environment goes. It does not emit greenhouse gases or other chemical pollution. Provided the radioactive products are kept safely contained, there is virtually no environmental impact.
Which of these is a challenge related to nuclear fusion reactions?
It is technically challenging to create these reactions safely and efficiently.
