If a nuclear overnight CAPEX of $2000/kW is possible, as the South Koreans, the Chinese, and the GKG claim, why in the world would you run $4000/kW, let alone anything higher?

The answer is we've seen nuclear CAPEXes of $8000/kW and higher. Vogtle 3/4 is above $10,000/kW. Flamanville 3 is in the same range. This cannot happen in a properly functioning, competitive market. In such a market, there is only one price, the best price. If nuclear cost is as critically important to the planet as Figure 6 claims, we must figure out what turns a $2000/kW plant into a $10,000/kW plant and eliminate it. The GKG publication Why Nuclear Power has been a Flop attempts to do just that. //

Only truly cheap nuclear offers humanity what it must have: both cheap electricity and low CO2 emissions. Expensive nuclear offers humanity the choice of impoverishment or global warming.
