Arnie Gundersen, Chief Engineer at Fairewinds Energy Education:
The seismic response of these buildings is not really designed for moist soil. The soil’s a lot wetter now than it was when the plants were designed.
So, now you’ve got plants essentially sitting in a mud. And so their seismic response in the event of a severe earthquake is going to be much worse – in other words they might topple.
If they build and keep the water in, they risk changing the seismic characteristics of the building, and that’s not a good thing […] something called liquefaction — when you have water and soil together and you shake it just right – the soil essentially disappears, taking buildings with it.
It can happen at Daiichi because of the things that Tokyo Electric is doing to keep the radiation from getting into Pacific.
