Good thing, they build earthquake-proof nuclear installations along the West Coast, eh?

Well, in all fairness, pretty much anyplace you could slap a nuclear power plant in Japan would be in an earthquake and tsunami zone.

The problem there was that the emergency back-up core cooling required water to be pumped, with electric pumps, UPHILL to cool the core. Guess what? If you're in a catastrophic situation, you don't have power, or enough power and nothing is being pumped uphill and your core melts. General Electric, eh?

It costs a bloody fortune to add the feature but each CANDU reactor houses a huge tank of water right over the core and it something goes really wrong, the water flows downward by gravity.

If gravity fails ... well, all bets are off.
