Modern SMR nuclear reactors use precious generation spent fuel rods as their own fuel, and by design, are impossible to cause a meltdown.

I have 21.1kW of solar panels on my barn, and nuclear is still the cleanest energy at scale, but a lot. Also, solar panels can’t be realistically recycled and when the panels are done, they’re destined to landfills. At least they’re finding ways to recycle wind farm rotor blades.
