The US Navy seems to be able to do it

The navy uses nuclear reactors for tactical reasons, not economic reasons. Nuclear-powered ships are significantly more expensive.

The US Navy builds many reactors for the price of this power plant.

A Virginia class submarine in 2023 costs $4.3 billion (that's for the whole submarine), it has a 210MW S9G reactor.

The Vogtle Unit 3 was $17 billion over budget, for a $30 billion total budget, for 1,100 MW.

$204MM / MW for the US Navy vs $273MM / MW for Georgia Power et. al.

This project makes nuclear submarines look like a bargain!

Following the references from the Wikipedia article, I found that the S9G reactor is rated for 210 megawatts of thermal output. The AP1000 reactor that this article is about has a 3415 megawatt thermal output:

The naval reactor is a lot more expensive per unit of output.
