You know what uses even less fuel and produces even less waste

That's false, solar and wind power consume considerably more resources than nuclear and therefore produce considerably more waste than nuclear power.

What's more, because of their low load factor and intermittency, they require oversized capacity, storage devices and redundancy, further increasing their footprint.

at the same or cheaper cost

Only if you don't account for oversizing the capacity, the storage and redundancy induced by the wide adoption of solar and wind power.
