This meme is nonsense. Fast reactors do not alleviate the problem; if that were the case, waste would not accumulate around the world, to the point that no one knows what to do with it. There are no geologically safe storages for millennia.

A nuclear power plant has a useful life of about 40, at most 50 years, after which there remains a ruin that must be eliminated, a deconstruction that can last decades to eliminate thousands of tons of debris with medium and high radioactivity. This, adding to the storage problems, is a tremendously expensive process that is also carried out with public money, not by the owner company. In the event of an accident, see Harrisbourg, Chernobyl, Fukushima and some more, large areas of the country remain contaminated for many years.

The statement spread by nuclear companies that nuclear power plants do not pollute during their operation is a lie. They produce almost as much CO2 as carbon plants, since they require transportation from third countries, if they do not have a Uranium mine nearby, apart from the energy requirements in the enrichment processes in centrifuge plants. The warming of surrounding aquifers due to cooling, with important impacts on local fauna due to the proliferation of algae and lack of oxygen in them. Not to mention the risk of a meltdown due to lack of refrigeration, when the aquifer disappears due to a drought, which precisely now with global warming is a real risk.

The promotion of nuclear power plants has pure economic reasons for certain companies and in some cases weapons reasons to justify the production of the necessary Uranium and Plutonium.

Nuclear energy is only acceptable in medical applications with short half-life isotopes and in space probes. A nuclear alternative will only exist with fusion plants, the current fission plants are not an option.

The reason for rejection is not hate, but rather knowledge of the cause and consequences.

Do they actually produce as much CO2 as carbon plants? Do you have a source for that claim?

In terms of nuclear waste storage, the IAEA claims 390,000 tonnes were generated between 1954 and 2016, and a third has been recycled.

The US EPA claims the US generated 6,340 million metric tons of CO2, and 25% were for the electric power economic sector.

The nuclear waste is stored on site, but I imagine carbon waste is stored mostly in our atmosphere...

The narrative I have heard is that nuclear energy waste is much more manageable than fossil fuel waste, but if nuclear energy has emissions or scaling problems I'm not aware of, I'd be happy to revise my preconceptions about it.
