Thanks :):)

I'm not really sure about the answer but this is the info i can give u about nuclear fission and fussion

nuclear fusion

- used to power sun

- process involves joining atomic nuclie together

- releases lots of energy

nucler fission

- involves splitting atomic nuclei into smaller pieces 

Sorry if it's no help !

Not really. The problem with nuclear fusion is that it needs special containers due to the high temperatures and pressures. I suppose there are dangers with the high temperatures and pressures. However it can be easily controlled. The reason why it's not really used for energy is because it is quite difficult to get started. We can only reach the required conditions for a matter of seconds, and it is very hard to do. I read on a website that 100 million kelvin is needed, which is 6 times hotter than the sun. The reason for this is that the hydrogen nuclei repel each other, so they have to be forced together.

Thanks this is helpful :)

I know that fission is used to heat large amounts of water which can then be used to power things like wind turbines. 

Is it true that fusion cannot be done safely, so we don't use it for energy?

Thanks :)

Thanks loads! :)

So,, fission is more commonly and easily used for electricity generation than fusion which is rarely used?

Sorry, thanks ;):)

Yeah fission is really easy to do and is commonly used.  Fusion is not really used much because of how difficult it is to achieve the right conditions.
