What are Nuclear Fusion Reactor?

is the process by which two or more [|atomic nuclei] join together, or "fuse", to form a single heavier nucleus. This is usually accompanied by the release or absorption of large quantities of [|energy]. Large-scale thermonuclear fusion processes, involving many nuclei fusing at once, must occur in matter at very high densities and tempertures. Fusion reactions power the [|stars] and produce virtually all elements in a process called [|nucleosynthesis]. Although the fusion of lighter elements in stars releases energy, production of [|elements heavier than iron] absorbs energy.

What the future holds for Nuclear Fusion?

Science may only be a few years away from showing that fusion can work: thos is teh break-even point,where we get out more energy than we put in. It will then be a number of years before a functioning fusion reactor is developed. But scientist are optimistic that controlled fusion power will be acheived. The rewards are great- an unlimited source of nonpolluting energy. 

Cons

 * ** Ignition temperature is extremely high. **
 * ** Any substance at these high temperature are in the plasma state which is very difficult to contain. **
 * ** Large-scale fusion reactions are very expensive. **
 * ** May require more energy to create fusion than one can harvest from a reaction. **
 * ** Nuclear Fusion was not a controlled reaction until now. **

Pros

 * ** The fuels that could be used are relatively inexpensive and readily available. **
 * ** The products of a fusion reaction are not radioactive, thus thee are no nuclear waste problems. **
 * ** Fusion is not a chain reaction, therefore it can be stopped at anytime and there is no threat of a meltdown. **
 * ** Fusion would be a virtually inexhaustible energy supply that could eliminate most of the world's dependence on other fuels. **
 * ** fairly expensive to create but virtualy inexpensive energy **
