Besides nuclear energy being uncompetitive, it's highly radioactive hazardous waste will need to be managed essentially forever. 
We can't just bury it either, because we are talking about it being hazardous for hundreds of thousands of years.
Those costs are incalculable. It should be a no-brainer, that it's time to stop using this ridiculous form of energy.
Plus as these facilities age, our risks increase. I would hope Fukushima, Chernobyl and TMI were enough lessons learned.
The clock is ticking.
