OK, so whilst we wait the 7 years for the reactor to be built we should, what? hope that coal and gas stops polluting in the interim? Or should we continue to use the tech that, whilst not perfect, is better than the currently most widely used alternatives?

Nuclear is expensive, slow to deploy and has a inherent risk that renewables do not:

Plus the ewaste renewables produce can be recycled easily, cheaply and with far less risk than the waste for nuclear. Is the process perfect? No, so lets concentrate on improving the circular economy around recycling panels, turbines etc. Spend the money and effort on improving the tech that is already proven to be cheaper, more effective and ready now.

And seven years seems quite optimistic considering how effectively local governments and committees of concerned NIMBYS have been blocking any new nuclear construction for like, my entire lifetime, at least in the US. Apparently nobody wants a nuclear power plant going up near them and they find a lot of creative ways to jam up the works. I'm not sure we have the time to try to ram dozens of nuclear power plants through those folks while the world is burning.

Definitely. That 7 years was just the construction phase. All in the average nuclear plant takes about 14 years to build from planning to switch on.

Reactors can be built in as little as 3 years, thanks for your outdated input.

Cool, but that's not how averages work, is it.

Also the fastest Nuclear power plant construction in the world is currently held by Kashiwazaki-Kariwa Unit 6 NPP at 5.41 years, construction start to commercial operation:

That often quoted 3 years doesn't include inspections, testing etc.

All I'm hearing is we should have started a decade ago and people are still giving bullshit reasons to not start right now. You're part of the problem my man.
