They're expensive because of, arguably, over regulation. The are not inherently expensive, we've just declared them so. The next response will be "all that regulation is needed" but it's arguably that the over regulation is killing people by the unintended consequences of keeping things like coal viable, etc...
Right. There are countries that aren't particularly wealthy and rely on nuclear power just because they don't have reliable fossil fuel sources.
The over regulation is there becaused the Soviets have shown us what under regulation, disregard for safety and zealotry can lead to.
Even Japan managed to screw up. Yes, it took a 9 Richter scale earthquake and a tsunami, plus some mistakes that were made during development.
Passive safety works just fine, but it's expensive to build huge water tanks and containers that could withstand 9/11 type of events.
I meant, the particular way the Navy does it might be too expensive for some reason. Do you know anything about that?
