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

Ah so now it's one of those superposition reactors which has the all the upsides all the different people trying to sell them imagined after building half of one and having it fall apart in a year, but none of the downsides. Also a U235 reactor running Th in place of U238 for a breeding ratio of 0.5 somehow means U235 ia sn't needed anymore.

The disconnect is you are pretending a half-proof-of-concept of the easiest bit is all the hard bits being complete.
