Ora, how could you believe that nuclear is scarier than coal? Fission disasters happen because of poor judgment (such as a plant like Fukushima, built on a vulnerable shoreline and an active fault line), bad safety standards (such as those resulting in most of the disasters in the United States, as well as Chernobyl), operator or worker error (which is no different in coal mines; see Centralia, PA, USA), or a natural disaster outside of the control of basically anyone, but again, that can be the case with a coal mine as well. Disasters in coal mines, like that in Centralia, can be just as long-lasting as any nuclear disaster, and cave-ins leave mine tunnels obsolete, not to mention the hundreds of miners behind the cave-in that can literally suffocate to death while waiting to be rescued, if they are ever rescued at all. Issues stemming from nuclear waste on an environmental level are no more scary than the prospect of blasting away mountaintops or other viable areas with dynamite in order to access the resources below, the primary difference being that nuclear waste contamination is not guaranteed to happen in order to access the resources to begin with, whereas blasting nowadays often is. On top of that, as I think you seem to acknowledge, coal burning is far, far more devastating for our health and for the health of the biological communities living in a coal-burning area than nuclear power ever would be, barring a total meltdown on a Chernobyl type of scale.
And, if you forget that fission is not the ultimate nuclear technology (fusion is) that we are shooting for, whereas coal mining is at its most refined and most complete foreseeable state and coal burning is at its least impactful and least devastating state right now, you're out of your mind. Successful transmission of energy via nuclear fusion and safe storage of said energy would solve our energy problems, just like that.
