A fusion barrier refers to the repulsive charge between two nuclei that must be overcome to initiate fusion.
Do you mean how much power does it produce? None are working as yet.
Everything, so to speak, is nuclear powered, because everything ultimately gets its energy from the Sun, and the Sun's energy is fusion nuclear power. This includes the food we eat and the raw materials we are made of.
If you mean covalent bonding...well then they bonded.
When nuclear fission takes place heat is produced, this is all usable to produce steam for the power plant. Perhaps you mean how much of the U-235 is usable? In a light water reactor the fuel is around 4 percent U-235 to start and is discharged at around 1 percent or perhaps a bit less, so you could say that about three quarters of the original U-235 in the fuel is used.
Barrier of death
Fusion is a nuclear physics process. Atomic nuclei with the same charges are joined together, where they form a heavier nucleus. This causes either an absorption or a release of a high amount of energy
False
Nuclear fusion refers to a nuclear reaction wherein two light nuclei fuse to form a heavier nucleus. This process releases energy.
I think you mean "Cold Fusion" It is the (currently) hypothetical nuclear fusion reaction which happens at ambient temperatures?
You probably mean nuclear fusion
Please elaborate on "they" as no comparison can be given otherwise. Do you mean?: "How is nuclear fusion different from regular nuclear reactors (nuclear fission?)"
I think you mean nuclear fusion, the reaction that powers the sun.
Do you mean how much power does it produce? None are working as yet.
A nuclear accident is the unintended release of nuclear radiation into the environment, such as damage to a nuclear reactor or to a nuclear weapon (plane crash carrying nuclear bombs, etc). The two basic forms of nuclear weapons are fission and fusion weapons.
By a nuclear fusion you must mean an H-Bomb. This releases tremendous heat energy so it will vaporise a lot of water if it explodes near the surface. The shock wave will also cause massive waves to be created.
Nuclear bomb can mean either fission or fusion bomb. Hydrogen bomb means fusion bomb. The fusion bomb can be built with any yield one wants, just by adding more stages with more fuel. The fission bomb has a theoretical maximum yield that cannot be exceeded.
Not sure what you mean... The Sun gets its energy from nuclear fusion; the original energy is the potential energy (nuclear energy, in this case) stored in the hydrogen-1 nuclei.
