I agree that it's a major failure, but doesn't that just mean that nuclear is even safer than people expect? Safety systems, backup safety systems, backup-back

I agree that it's a major failure, but doesn't that just mean that nuclear is even safer than people expect? Safety systems, backup safety systems, backup-backup safety systems can go down, and yet, the plant kills nobody. Even though the radiator had a meltdown, it was passively contained and the radiation didn't leak out in dangerous quantities. You mention that we don't know how likely a bigger containment was to occur, but I think there's barely a nugget of truth in that. The way the radioactive material was contained is very well understood. The safety systems worked, despite anything TEPCO did.
