Power requirements on a sub vs a civilian power plant are on a different scale. A vessel reactor is small enough it easily contained and shielded, by comparison. You get free cooling. And it doesn't have to be cost effective.
I'd like more civilian reactors too. But scaling is an issue.
No one gets nuclear power, including the people with the subs. We're all phasing it out, out of a shared understanding that the political fight is worse than the climate and other impacts of just letting it die.
