If you mean nuclear power then:
It is helpful because it has an almost infinite supply of fuel and is fairly clean energy, but if the protection from the radiation is defective it can spread harmful radiation all around the area, like in Chernobyl and Japan, although the former is a very extreme example.
nuclear is good and bad at the same time.
Nuclear radiation is neither good nor bad, it is a natural phenomenon. Natural phenomena cannot be good or bad (this is an ethical/moral judgement), they are simply facts.
Nuclear reactions can be both good and bad. They can produce clean energy, like in nuclear power plants, but also be used to create nuclear weapons which have destructive capabilities. The key is in how nuclear reactions are managed and controlled.
Mainly that no good solution has been found to dispose of the nuclear wastes.
Nuclear weapons are tools. Tools can be neither bad nor good. The only things that can be bad or good are the people using them and the purpose those people use them for.
All nuclear esplode is ood
In each atom of our body, we have a nucleus. This is a Good Idea.
Nuclear power is neither good nor bad. The way nuclear power is produced (Safety) can be good or bad, though. Nuclear power can be generated by small power plants, creates no air pollution, and is safe when done right.
Energy. How we use it makes it a good thing or a bad thing.
Nuclear is a bad source of energy because it pollutes the Environment. It Kills Forna and Flora, It Creates holes in the ozone layer because it pollutes the air. I am a Scientist at CSIRO and our studies have proved this.
Plutonium is very important for nuclear weapons and for nuclear fuels used in nuclear reactors. But plutonium is also toxic and radioactive. See the link below.
there are no bad things about the nuclear power reactors
