Over the last decade the US Navy has commissioned 1-2 new nuclear reactors per year. They currently operate 100 reactors, more than any other org on the planet.
The US Navy has managed a total of 273 nuclear reactors, 6200 reactor-years, over 177 million miles, averaging 4 new reactors per year over 70 years.
They have done this with a perfect safety record. Zero accidents. Zero injuries, zero deaths, zero environmental pollution.
US Navy Cost: $2 billion for 2 x 400 MW reactors in Ford-class aircraft carrier
NuScale: $10 bn for 500 MW reactor
Westinghouse: ~$8 bn for 1000MW reactor
Military reactors should be more expensive, not less, because they operate under harsher conditions. But they aren't, because the US Navy doesn't have to go through the NRC.
Naval reactor power ratings are for thermal output. You can assume that about 1/3 of the thermal output can be converted to electricity when steam from the reactor is used to drive an electrical generator:
Assuming that your cited numbers are correct, "$2 billion for 2 x 400 MW reactors in Ford-class aircraft carrier" translates to 267 megawatts of electrical output for $2 billion. Or $7.5 billion for 1000 megawatts of electrical output. This is not much cheaper than "Westinghouse: ~$8 bn for 1000MW reactor."
