The Pickering plant is believed to sit on a geological fault line. But officials at the province's publicly-owned utility say the risks are much smaller.
Ok, the CNSC and OPG have no credibility, but BELIEVE ME! :) Anyway, in the last fading spurt of interest with earthquakes, we had a huge study on the Pickering Fault Urban Myth. It was my glorious ride into the sunset before they kicked me out.
So I spent a million bucks on studying the Rouge Valley. Lots of drilling and the rock is as solid as my opinion. :) Really, I have since gone into the whole megathrust thing, and the big fault is under Hamilton. This might not be such a great thing, but it assures that Pickering and Darlington are hit with more normal seismic motions, probably under 20 cm/s.
I'll have to go with Tom Adams there, that they need some more humility. It's all the little things that will add up, not the big hardware that has been traditionally seismically qualified. No earthquake in the world can touch that stuff! But that's irrelevant. Somewhere in my writing, I have outlined the scenario for the Great Toronto Earthquake, and it's not pleasant.
Now we know the Tremendous Abuse of Geology, from the Niagara Tunnel and the Bruce Thing, but there is no Pickering Fault.
