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
The innovation is there but it’s not viable yet for a country, or even city wide grid. Hydro is okay but severely limited by geography, rocks up a mountain could work too but it’s also limited by geography to some extent.
