The power is cheap and will scale: Many European countries get the majority of their power from it
Many countries have had no choice but to attempt the nuclear route and would rather go another way. Many countries still face massive cost overruns building Nuclear plants. Additionally, where's the accounting for the expense of keeping the growing piles of waste potentially for a million years? Where's the accounting of the CO2 and other environmental damage from the mining and enrichment phase?
We have plenty of nuclear fuel: There won't ever be a nuclear fuel crisis because before we've used the enrichable uranium ore, and then reprocessed and reused all of the nuclear waste in our breeder reactors, the sun will be dead.
If you say so.
It's safe: If the only reason for not going for it is an accident 30 years ago when the technology was in its infancy that's great
the threat of Human error/stupidity/wilful sabotage is alway there. FYI, there are accidents of varying degrees of severity all the time. Besides, the longer we go without a Chernobyl type event the more lulled everybody becomes. Already Alberta is floating the idea of 12 never-built-before reactors to supply the energy to extract Oil from the Tar sands without the sarcophagus because these new plants theoretically can't melt down and darn it if building all those pesky safety features takes time and money.
It's available now: We cannot wait for the perfect power supply. We need to change over now. We've got the fuel, the tech, the experience.
All we need is for the public to get their heads out of their asses and learn to accept compromise.
Wind, Solar, Solar Thermal, Geothermal ect. are also ready to go now. Nuclear still carries great risks whether you want to admit it or not.
