It's relative harm. New nuclear is far cleaner than coal, and can slot into it's place in the grid. We should have done this decades ago, but the plans languished till china found out about them. (Much to the designers joy)
It's also not an either/or situation. As china is demonstrating, there is a limit to how quickly you can roll out renewables. Doing other, pollution reduction in parallel makes sense.
Taking nuclear off the table was the biggest win the oil barrons pulled off.
On a plus side, we will finally find out if fusion is viable in the next 5-10 years. The first over-unity test reactors, designed for sustained operation are being built.
Renewables are cheaper than building new reactors. Fusion is always viable in 10 years.
Fusion has been 10 years away, with proper funding. It never got that funding. It struggled to maintain the break even funding to keep skilled people employed, and the lights on.
The difference is that over unity has been achieved, in a normally sustainable manner. The funding is such that it's 5-10 years at current funding. Most of that is building the actual test plants.
I fully agree that renewables are currently the best cost option. The catch is that they are not viable everywhere. They are also inherently low density, so can get expensive in certain areas.
Basically, we want a mix of options, to fit local requirements. Nuclear (and later fusion) should be part of the plan.
In practice, I'm of the take what we can get. We need to crash CO2 output, and we need to do it yesterday. Anything speeding that up is a win, as far as I'm concerned.
Fusion got billions in funding and it led barely anywhere. Meanwhile renewables are the cheapest mass market options.
