Is nuclear power safe??

Radioactive isotopes? The ground is where they are before we mine them.I think maybe you guys aren't thinking the materials chain through, here. And apparently you don't know about waste vitrification - no risk of isotope leaching, even over thousands of years. Nuclear energy is and continues to be an excellent idea, particularly forms such as fusion that don't produce radioactive wastes. But much of the issue here is that you've heard about radioactive waste, but you've never heard about things like hydrofracking waste or fly ash waste, because nobody's ever made a movie where fly ash turns four turtles into ninjas.

Um, no, it doesn't. It sits there in holding levees, hundreds of millions of metric tons of it, until the levee gives way and it poisons an entire river. Or they try to bury it and it leeches a million tons of arsenic, mercury, and lead into local aquifers.I think maybe you don't know what "fly ash" is. If you did there is no way you would think it simply evaporates into thin air as soon as you turn off the plant. But again - nobody's ever made a movie about fly ash turning ants into leviathans, so you're not concerned about it, even though it's responsible for far more death, far more toxic exposure, far more cancer, far more destruction of natural environments than nuclear waste. Everything is around for thousands of years. There are coal seam fires that have burned for all of recorded human history.
