Why do you use fission reactors not fusion reactors?

Answer 1

No way has yet been found to reach break-even in a controlled fusion reaction and get as much energy out as was needed to put in to start the reaction. To make a reactor you need to go past break-even and release extra energy.

Answer 2

Fusion would be far more prefferable to fission in terms of energy generation, however current technology limits our ability to create and sustain a viable fusion reaction that generates power like a fission reaction does, often times, with current technology, more power must be put in to the fusion reaction to sustain it than what comes out of it.

Minor detail, no fusion reactor experiment has ever reached "breakeven" (the point where energy output equals energy input). While "breakeven" is an important point for research purposes, a practical reactor would need to far exceed that to be generating usable power. And we have been working on the problem for well over half a century.

Answer 3

Only beacuse of starting trouble. Any way we need billion kelvin temperature to start with for which we have to rely on fission reaction.

One more important point we cannot have a controlled fusion reaction as we do so in fission ie nuclear reactor using control rods.

Answer 4

At this time nuclear fusion is only practical in bombs and stars. Since the early 1950s various experimental apparatus have been tried to determine how to build a fusion reactor. None of these has yet reached breakeven (the point where the same amount of energy is released as needed to be applied to initiate fusion) and one needs to go far beyond breakeven to make a reactor to generate usable power.

Every 10 years or so some fusion researchers will claim usable reactors are only another 10 years away... but we are still waiting.

Answer 5

nuclear fussion process is not followed in most of the power plants because it is very difficult process to combine the atoms .rather than spliting the atoms.nuclear fission process is very easy that to split atom.

Answer 6

Fission reactions are currently more technologically feasible and economically viable, as fusion reactions require extreme conditions to initiate and sustain. While fusion has the potential to be a cleaner and safer energy source than fission, it is still a developing technology that has not yet been scaled up for practical energy production.

Answer 7

Fusion reactors have turned out to be much much more complicated to make than anyone had ever anticipated. But fission reactors are easy to make.

Answer 8

because we can't make fusion reactors work, yet. fission is easy though,
