Is Nuclear fusion accident prone?
Nuclear fusion is considered to be inherently safer than nuclear fission because it does not involve chain reactions and cannot lead to meltdowns or explosions. However, there are still risks associated with equipment malfunctions, radioactivity, and other operational issues that need to be carefully managed to ensure safety. Overall, while fusion is not accident-prone in the same way as fission, it still requires close attention to safety protocols.
What are the main advantage of a fusion reactor compared to a fission reactor?
Fusion reactors produce energy by fusing atoms together, similar to the process that powers the sun, whereas fission reactors split atoms. Fusion reactions in reactors have the potential for abundant fuel supply with deuterium and lithium, low radioactive waste, and enhanced safety due to the inherent characteristics of the fusion process. Additionally, fusion reactions do not generate long-lasting radioactive waste like fission reactions, making them potentially more sustainable in the long term.
What is the difference between the use of fission as an energy source?
The difference between the use of fission and fusion as an energy source is that in fusion reaction, 2 or more light atomic nuclei fuses to form single heavier nucleus while in fission reaction, heavy atomic nucleus is usually splited into smaller nuclei, other particles and radiation.

Is nuclear fission safe?
Nuclear fission can be safe when managed properly with appropriate safety measures in place. However, accidents such as Chernobyl and Fukushima have shown that there are risks associated with nuclear fission. It is important for strict regulations, inspections, and maintenance to be in place to ensure safety.
Nuclear energy is an alternate energy source produced from atomic reactions?
There are two: Nuclear Fission and Nuclear Fusion. Fission is when a neutron is fired at an element with a high atomic number (usually Uranium) which then splits, releasing energy and more neutrons. this produces a chain reaction, which continues until all nuclei have been split. Fusion occurs in stars and a few experimental reactors, and happens when two forms of Hydrogen nuclei (Deuterium and Tritium) fuse into an unstable nucleus, which in turn splits again into Helium and a spare neutron. Fission can start at any temperature, but Fusion only when Hydrogen is in a plasma state.
How does a fusion reactor work?
Fusion energy is created when nuclei are forced (or fused) together. . Nuclei, in the form of a thin gas, are magnetically suspended and heated to 150 million° C in a donut shaped vacuum chamber. The nuclei snap together giving off energy and helium. . Fusion (fusing nuclei) should not be confused with fission (splitting nuclei). Both processes utilize the strong nuclear force to produce energy but have significant differences. Two most prominent differences are ready to use technology (fission wins on that point,) and environmental safety (fusion has next to no radioactive waste or risk of melt-down). . Some fusion systems promise to produce energy without steam turbines, generators, cooling towers, and other energy sapping devices that must be used with coal burning and fission power stations. But to accomplish this fuels such as the rare helium-3 at still hotter operating temperatures are needed.
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.

Is nuclear fusion used as an energy source in power plants?
Nuclear power plants use controlled atomic fission to generate electricity. Atoms of the fissile material are split and part of their mass is converted to energy in addition to neutrons being ejected from the nucleus. These neutrons impact other atoms within the fissile material which then release further energy and more neutrons. The reaction is controlled by absorbing most freed neutrons with material so an uncontrolled chain reaction doesn't occur like the atom bomb used in WWII. The energy released produces heat (and radiation) which heats liquid into steam turning turbines connected to electric generators to make electricity. The highly radioactive spent fuel is a dangerous waste product that must be warehoused for many lifetimes. Conversely, the simplest type of nuclear fusion, which may become a reality this century, converts hydrogen atoms into helium atoms and produces no radioactive waste products.

What is one difference between nuclear reactors and nuclear weapons?
Reactors use thermal (slow) neutrons, fission weapons use fast neutrons.Reactors all use fission, weapons can use fission, fusion, or any combination.Reactors can use delayed fissions making them respond slowly to control changes, weapons complete their reaction too fast for delayed fissions to happen.Reactors have control rods and their energy release can be adjusted or even turned off, weapons have no controls and release all their energy in a few microseconds once triggered.etc.
