Thorium fuel cycle is nearly the same as the uranium fuel cycle in regards to downsides. It just requires breeders, which you could use with uranium too. The only real benefit of thorium is that it's more plentiful, but the cost in nuclear power isn't in Uranium.
Toxic/Radioactive waste is obviously toxic and radioactive, but how bad that really is is kind of overblown especially if you compare it to the harm caused by popular existing methods like coal/etc. When adjusted based on energy produced, there's more than one study out there showing how Nuclear is significantly safer than coal by a very wide margin. Coal ash is also radioactive and coal plants have very limited requirements to prevent it from escaping to the environment.
Even 'Radioactive Waste' really only feels scary because all of the bad stuff is condensed into a much smaller package when you adjust based on energy produced again.
yes, absolutely. we germans should've shut down coal plants first. but there's no point in reactivating the nuclear power plants, especially because we are literally producing more power than we can use. 60% of which is renewables. some providers will give you energy for basically free, as long as you use it at night when everything shuts down.
