I don’t get it. Current nuclear power solutions take longer to set up, have an effectively permanently harmful byproduct, have the (relatively small) potential to catastrophically fail, almost always depend on an abundant supply of fresh water, and are really expensive to build, maintain and decommission.
If someone ever comes up with a functional fusion reactor, I could see the allure; in all other cases, a mix of wind, wave, geothermal, hydro and solar, alongside energy storage solutions, will continually outperform fission.
I suspect that the reason some countries like nuclear energy is that it also puts them in a position of nuclear power on the political stage.
In what universe do those other power generation methods even come close to nuclear power?
It would take about 800 wind turbines or 8.5 million solar panels to replace the power output of one nuclear reactor.
And the fissile material can be reprocessed after it’s been spent. Like 90% of the spent fuel can be reprocessed and reused, but the Carter administration banned nuclear waste recycling in the US for fears it would hasten nuclear proliferation.

Wind, hydro, solar, and geothermal are all great. Anything is better than coal or gas power generation. But to say these green power generation methods come close to nuclear… not a chance.
Those 800 wind turbines can be built in a month. Building a nuclear plant takes decades. And nuclear fuel reprocessing had never been economical by a long shot. Your pipe dreams will always regain just that and that's before we even start talking about proliferation and nuclear waste.
In China they do it in 6 years...

I'm very glad I don't live anywhere near one of those.
And why is that?
The performance of nuclear power must be calculated in relation to its cost and risk. And here renewable energy is more than competitive.
I can set up 20 GW of solar panels to match the capacity of a 4 GW nuclear power plant. And I can set up 20 GW of PV in a year. China installs about 30 GW of solar capacity in a quarter.
It takes about 8-10 years to build a nuclear power plant. In 8 years, I could have installed the equivalent of 8 nuclear power plants using Solar PV that it would take me to build one nuclear power plant.
But then you don't have power at night. Cost comparisons of renewables vs nuclear very often neglect storage. It is not a trivial cost. Nuclear doesn't perfectly match demand either, but it can provide a baseload.
It's not renewables or nuclear, it's renewables and nuclear.
Then get to work.
