80% of the world's nuclear fleet are in fact light water reactors - like Fukushima - which require continuous cooling and a constant source of power.
Even the latest passive safety proposals like liquid fluoride thorium reactors don't conclusively solve the fundamental problem of overheating after a cooling system failure [1].
Downvotes are often attached to inconvenient truths.
The safety of nuclear power is based mainly on wishful thinking. It's the classic folly of chasing short-term cost savings and ignoring long-tail risks.
"Today's nuclear power plants are inherently unsafe. Most that are in operation depend on active cooling systems to prevent a meltdown."
