Anon isn't dumb, just simple. Nuclear energy can be the best solution for certain situations. While renewables are the better choice in every way, they're effectiveness isn't equally distributed. There are places where there just isn't enough available renewable energy sources year round to supply the people living there. When energy storage and transmission methods are also not up to the task, nuclear becomes the best answer. It shouldn't be the first answer people look to but it is an answer. An expensive answer but sometimes the best one.

Also nuclear waste doesn't have to be a problem. If anyone was willing to cover the cost of burning it in a breeder reactor for power or burry it forever. It just is because it's expensive.

Anon forgets the nuclear waste.

Nuclear waste is pretty tame. Compare gloves that were used once to turn valve on pipe in reactor room to shit from coal in your lungs. Even most active kind of waste everyone thinks of - spent fuel - consists from about 90% of useful material.

EDIT: 95-98% of useful material.

Anon also forgets that the plants for the magical rocks are extremely expensive.

Actually not. Especially cost of energy compared to one of coal.

The costs used for wind/solar energy never included the cost of the required buffer storage, and even the rare few people who include that never factor in frequency stability which to this day is maintained by the giant steam turbines everyone wants to get rid of. It will not be trivial to solve the frequency stability problem; it will likely require massive investment in pumped water storage, flywheel storage, or nuclear energy, and these costs once finally included in the real cost of wind/solar will hurt its value prospect considerably.

As for nuclear waste: the overwhelming majority of nuclear waste generated over the lifetime of a reactor is stored onsite. Only the smallest amount of material is what will actually remain dangerous for a long time, and many countries have already solved this problem. It's a seriously overstated problem repeated by renewable-purists who usually haven't even considered how much frequency stability and grid-level storage have and will add to the cost of renewables, meaning they have not given a full accounting of the situation.
