I was referring specifically to the parent's concerns. Fuel disposal is certainly a problem in nuclear in general. I'm not sure about this specific reactor type; it's possible it produces less-troublesome waste, but I don't know. Most power generation is exceedingly bad for the planet in one way or another, but nuclear is certainly a whole lot better than fossil fuels.
