No. They have none.
Radiation is an emission. For example, gamma radiation from a nuclear decay is an emission of energy, photons.
It does not produce greenhouse gases, as fossil fuels do.
Nuclear energy is the world's largest source of emission-free energy. Nuclear power plants produce no controlled air pollutants, such as sulfur and particulates, or greenhouse gases. The use of nuclear energy in place of other energy sources helps to keep the air clean, preserve the Earth's climate, avoid ground-level ozone formation and prevent acid rain. Of all energy sources, nuclear energy has perhaps the lowest impact on the environment, including water, land, habitat, species, and air resources. Nuclear energy is the most eco-efficient of all energy sources because it produces the most electricity relative to its environmental impact.
Uranium is a radioactive substance. Nuclear power production is carried out by the energy supplied by nuclear reactors. Nuclear reactors control the energy emission by nuclear fission reaction in radioactive substance when bombarded by neutrons.
Renewable energy releases the least amount of greenhouse gas per kilowatt. After renewables come nuclear which is greenest. It has other issues though.
Nuclear fusion is the phenomenon in which two lighter nuclei get fused to form heavier nucleus with the production of energy. Best example is SUN and hydrogen bomb. But nuclear fission of breaking heavier into lighter with the emission of energy. Example uranium-235. So atom bomb Nuclear fusion has clean energy but fission has hazard energy
Using more nuclear power would help to reduce emission of greenhouse gases, but it won't reduce the need to import oil, as oil is not used much at all for electricity production. One way for the US to reduce oil consumption would be to use smaller cars, with smaller engines, and also to make industrial processes more efficient.
Because it does not cause pollution by producing greenhouse gases and contributing to global warming
Because it does not produce greenhouse gases
Coal energy releases greenhouse gases when burnt, causing global warming. Nuclear power has very little effect on climate change.
Greenhouse effect is due to greenhouse gases. We have to stop their emission.
Nuclear energy provides electricity which is good for humans, and for the environment it does not produce greenhouse gases, so that is good. However it has dangers too, so must be well controlled
