The nuclear energy can been seen at either way, and that is why it has both its supporters and its critics.
The nuclear energy is cheaper, cleaner, and nuclear centrals can produce much more and much more efficiently as well, so it can easily be seen why it can be extremely useful in a world where the energy demand is ever-growing.
On the other side, there's a huge risk with the nuclear centrals because if there's some problem, it can all turn into a catastrophe that will affect huge area. The consequences of a nuclear reactor exploding or leaking are long term, and takes lot of time that the area can be used for anything. Lots of human lives can be lost, and affected for numerous generations, as well as destroying the natural environment in a brutal way.
