It sounds unsound: $9.3 billion for a 462 MW capacity poweplant and $119 per MWh price without subsidies.

Current prices for off shore wind is generally around $4000 per KW capacity or $1.8 Billion for 462 MW capacity poweplant. So basically you still have $7.5 billion left.

24 hours of battery storage is around $2000 per KW capacity, and around $1 billion for 24 hrs backup of a 462 MW load

In practice Off-shore, can be much cheaper, a recent project was $1.4 billion for 600 MW capacity, and a $55 per MWh price.

So basically the final per MWh price projection of the NuScale project with government subsidies has progressed like this:
2016: $55 per MWh
2021: $58 per MWh
2023: $89 per MWh (or $119 MWh without government subsidies)
On shore wind is around $32 per MWh
Off shore wind is around $84 per MWh, projected to decline to $60 by 2030

Besides, it's actually more expensive than traditionally nuclear power, which has a LCOE of about 65$/MWh according to the IPCC and NEA, costs, say, 10 billion to build for a 1600MW power capacity, and performs better than gas power plants in the long term. It turns out there's a good reason nuclear reactors are typically built huge.

That LCOE for nuclear would involve unrealistic assumptions. The LCOE from Vogtle 3/4 will be much higher than that.

LCOE isn't calculated on the basis of outliers.

Apparently it should be computed on the basis of old, irrelevant historical data? Or maybe on the basis of promises on Power Point slides.

Do you know if the cost of R&D is being included for this reactor? If so, the subsequent reactors would have much more favorable economics

Sure if more expensive to build than wind, but have you included the cost of the fuel?

You need to calculate in Energy storage and multiple sites to counter the variability of wind
