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...
replyI meant, the particular way the Navy does it might be too expensive for some reason. Do you know anything about that?
replyRight. There are countries that aren't particularly wealthy and rely on nuclear power just because they don't have reliable fossil fuel sources.
replyThe over regulation is there becaused the Soviets have shown us what under regulation, disregard for safety and zealotry can lead to.
replyEven 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.
Thats the issue with those AGR reactors the brits have IIRC, perfect (or close enough) safety record, super complex and not economical to run.
