Which of these is a major concern of nuclear power plants? air pollution disposal of wastes ozone layer degradation releasing extremely cold water into the environment?

Nuclear Power Plants are one of the most environmentally friendly energy sources of the planet, very low emission of greenhouse effect gases makes Nuclear power a good alternative for obtaining energy, almost 19% of USA energy is nuclear and the majority of its waste disposal is in Nevada.

But Nuclear energy has some consequences that have to be analyzed carefully, while there are not many emissions of greenhouse gases, the massive construction of Nuclear plants could result in environmental degradation. Also, nuclear power Waste disposal is perhaps the most concerning aspect of this energy, these radioactive wastes are very harmful to live organisms, these wastes can last up to 10 thousand years to be degraded, because of this the Nuclear wastes are being buried deep underground to isolate them for that many years. Having such damaging wastes and no immediate way to get dispose them is a big concern for Nuclear power.

And if we include that accidents can happen, like the Chernobyl nuclear crisis the consequences of bad management of nuclear energy are what most concern the world about this "environmentally friendly" energy source.
