Personally, as it currently stands, no. But it could potentially be, given better waste treatment practices and far better regulation and consistently enforced safety requirements.
It's far greener than fossil fuels, when run carefully at least. But between the persistent issues with waste reclamation and harmful leakage, and the massive amount of damage that can be done when mistakes are made or safety is overlooked, I don't think it qualifies as "green".
So from a practical standpoint, I still think new resources are better spent developing infrastructure for solar, wind, geothermal, etc. But as we are phasing out other power sources, pretty much everything else should go before we start to decommission nuclear.
