Huh? Only one of those subs had issues with its nuclear reactor, but there was no "disaster": it was scuttled in a controlled manner (though unfortunately in a location that the IAEA disagreed with).
All the other incidents listed had nothing to do with their nuclear reactors; they would have all sunk just the same had they been powered by diesel fuel.
I'm not sure what you mean by the US Navy sinking two "catastrophically": none of the deaths listed on the page you link have anything to do with the fact that nuclear power was used.
However, you probably should have linked this section of the overall article on nuclear submarines:
It's weird that the section starts off with "Some of the most serious nuclear and radiation accidents by death toll in the world have involved nuclear submarine mishaps", as the following list doesn't seem to support that, only cataloguing 28 deaths and 162 cases that probably included lifelong health problems. (These numbers are not great, but still not as bad as for land-based reactor incidents, and tiny compared to deaths and health problems caused by burning fossil fuels.) They do claim "substantial radioactivity released" in several of the incidents, but don't quantify the effects, or what the effects would have been if it had been a land-based reactor (so maybe very bad!).
I hesitate to mention this (as I don't want to sound dismissive), but it might be notable to consider that all of these incidents occurred on Soviet subs, and that there hasn't been an incident since 1989. The navies of the US, UK, France, China, India, and post-Soviet Russia have never (at least as far as we know) had a reactor incident with their nuclear-powered subs.
