Three from the USA navy. It is a lie that the nuclear reactors on submarines have been safe. Two have been lost at sea (one was sunk in harbour)
Nuclear reactors on ships generally, submarines in particular, are a terrible idea. As evidenced by the fact that the US Navy has sunk three, two catestrophically. If the US Navy cannot do it, who can?
The number of oil spills that happened in that same time frame, that we're still trying to recover from, exceeds that by a great number. The environmental damage caused by those isn't purely theoretical.
Compare that, to the Exxon Valdez, and the Deepwater Horizon.
Why don't you keep reading the article on the list submarines that you referenced, all the way down to the 4th paragraph that talks about causes of sinking.
1 of 9 (Soviet K-37) was scuttled with no loss of life due to reactor issues spanning years. 1 had an undetermined cause of sinking with theories having to do with the usual submarine issues (fire, torpedo accent, ballast/pressure issues), not its reactor. All others were lost for reasons having nothing to do with nuclear reactors.
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.
I don’t think you actually believe that the bottom of the ocean is a good place to keep nuclear waste.
You would probably agree with me—and most other people—that a nuclear power plant, the was caught throwing their waste into the ocean, would be an environmental disaster. The US navy doing the same thing is also an environmental disaster.
Presumably the reactors in submarines are commanded to scram when the sub is in trouble.
So the reactor is a high corrosion resistant stainless vessel in non-critical state at the bottom of many tens (hundreds?) of metres of ocean.
All told, that doesn't seem an entirely unreasonable place for it. Even if it was critical, in the active state before the sub sank, it'd probably just heat water for a decade or too before it eventually cools down.
Even if it suffered a meltdown, that's not ideal, but I'm not gonna lose any sleep over it.
