Hasn’t the Navy already built these?

PWR’s yes, SMR no. Commercial PWR reactors were derived from the naval designs in the 1950’s.

The “new” thing is size of the SMR. SMR’s are small enough to be built in a factory, and then shipped to the site. Current commercial PWR’s are huge and have to be assembled on site.

Google “vogtle” to look at the AP1000 design. It's huge.
