Who lumped nuclear in there? As long as a nuclear plant has US standards for quality and testing instead of Japanese standards, we're all set. I do still prefer solar and wind but I wouldn't lump nuclear in with oil and gas since it doesn't produce CO2.

Fukushima Daiichi had four General Electric reactors. The same reactor design is used in several US plants. Peach Bottom [wikipedia.org] in Pennsylvania is one. All operating plants of that design will melt down if they lose cooling water flow for more than about 18 hours.

Unfortunately, the make and model of the generator itself had little to do with why it melted down. Their maintenance was crap. Their backup systems didn't work. They were too cheap to bury a landfill-style containment unit under the ground. Cheap and poorly run with lies about maintenance and safety = every asian company ever.

Well the fact that they needed constant active cooling (inherent to the design) was the main factor. Without that the accident would not have happened. Remark that they decided to shut down the plant before the tsunami arrived. But even afther a shutdown the plant still needed a constant flow of active cooling.
I never heard anything about poor maintenance. What I did hear in the documentary is that the backup power groups were flooded. So through their placement they were out of the game almost immediatell

You don't appear to understand what happened in Fukushima. That's fair enough - it's rather complicated, and some of the words are scary. The reactors melted down because the system that provided electricity and coolant to the reactors failed. That bit wasn't made by General Electric. That bit wouldn't even be allowed in that configuration in the US or Europe or anywhere else that cared about safety. That's the problem - not the reactors. Most (if not all) plants have a back-up power system which can

Have you read NUREG 1150 [nrc.gov], the NRC accident study that includes Peach Bottom? 18 hours after station blackout, core melting will start. The most likely risk is a fire knocking out power.
