What ‘cult-like’ love would this be? If you are in a climate emergency it’s worth exploring all energy options and nuclear is one option for helping with baseload. It would be dumb to ignore it.
We still need to decarbonize tons of other industries so why waste money on the one we have solved?
Good enough beats imaginary engineer perfect solutions.
So, the solar/wind waste bugbear is a red herring, since dealing with it involves solving a problem that would have to be solved in a nuclear-powered economy also.
The opposite is not true of nuclear waste: there is no high activity radioactive waste stream in a non-nuclear economy.
