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.
The view that the US has stopped producing nuclear reactors is actually pretty inaccurate.
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.
