Solar energy now overlaps in cost with nuclear fuel alone for "cheap" modular reactors (energy-utilities.com)

Uranium is $128.30/kg

After enrichment, conversion and fabrication that's $3400/kg for 4.95% fuel.

At 36-45MWd/kg and a net thermal efficiency of 25% or $12.5/MWh up front.

With a 90 month lead time (72 month fuel cycle and 18 months inventory) at 3% this is $16.2/MWh

Which some solar projects are now matching

Yeah, if you only want meaningful power on a sunny day in daylight hours.

Where's all this paradigm changing battery tech I keep hearing is on the way for 20 years?

You just don't need that much storage and at the same time battery storage is already being installed at an exponential rate, much like PV started to some 15 years ago. We also already have hydro and gas peaker plants that aren't going anywhere for the next 10ish years.
