The US builds a 700MW reactor every 4 years[1][2], and a 200MW reactor every 2 years[3][4]. The Navy has operated these designs (or very similar ones) for decades without incident, and considering the per-unit cost of the complete ships that feature them, they seem substantially cheaper than most of the civilian construction projects. My last boss had previously worked with some of the Navy's high-level nuclear administration people, and said their program was extremely well-run, partially due to a conservative, risk-adverse, albeit cliquish approach to reactor safety: "Don't ever come to us trying to change anything, we've already paid the blood tax to figure this stuff out, our processes clearly work very well, and we're almost certainly smarter than you and have already considered anything you want to suggest anyway."

I'm not sure why we don't fork the reactor designs with some minor changes for powering urban grid infrastructure....Hmmm, maybe a sneaky rollout would be to establish a bunch of "test reactors" physically on naval bases, but with grid connections to the local cities.....essentially subsidizing the national power grid with US Navy nuclear assets.
