There is so much "behind the scene" shit that outweighs the benefits.

Mining uranium still requires fossil fuels and destroys its environment. Uranium mines require billions of dollars to clean up. Most are abandoned and continue to emit radiation. Most of these cases are tragic social injustices to native populations.

Building the plants (including bridges, railroads, water diversions, levees, highways, runways, etc.) use fossil fuels and emit lots of GHG.

Transportation of nuclear fuel between its stages emits GHG and radiation throughout the entire process. While running, nuclear energy is extremely water intensive. Water will only become more of a precious resource in the future. With natural disasters becoming more frequent, it's also risky to continue building plants along the coasts. All plants currently require back up electricity since meltdowns have to be avoided at all costs.

Most plants expire around 40 years, but it is too expensive to build replacement parts since there is already a back up for new plants. Some of these old plants are abandoned and are still radioactive zones. Investing in an energy that produces extremely dangerous waste without having a waste solution implemented is so foolish. Most spent fuel pools are already over capacity and there are few locations on our planet that can even be potentially considered for permanent storage facilities.

If you don't believe any of this, just read "Contesting Nuclear Power: A Critical Global Assessment of Atomic Energy" or look up lifecycle assessments of nuclear fuel and nuclear plants. I'm not saying similar issues can't be applied to renewables or that fossil fuels aren't the devil, but utilizing atomic energy shouldn't be rushed. As of now, I think its consequences are too dangerous and we're too immature of a species to properly handle it.

All that being said, we have a ton of nuclear waste we need to get rid of. Bill Gates is working on a project called TerraPower that would use spent fuel for energy underground. It also would cut out the proliferation problem. It seems like the safest and most viable option at this point, so I honestly hope he comes through.

Okay, rant over.
