PWR Fukushima much worst than GE Mark 1

I don't think you can yet make the case this was a GE mark 1 centric event.

In other words, this outcome is rather mild to what would have happened if large PWR were sitting on the east coast of Japan.

I think the isolated loop of the PWR's primary system...this much higher pressure of the primary system, thus much harder to cool...

I think the PWRs would be a much more painful accident....

In other words, the core would have melted down much sooner and the pins would have skyrocketed to much higher temps...

I think tons more radiation would have been released to the world inviroment...
