Nuclear Expert Arnie Gundersen, Fairewinds Energy Education: There’s another problem down the road, 5 miles down the road, at the Fukushima Daini site. And that one, their Unit 1 there, they experienced a pressure increase inside the containment. No one is quite sure why that happened but it was shortly after the earthquake. So it’s certainly a causal effect. [...]

Gundersen: The tsunami that knocked out the Daiichi cooling pumps also knocked out a lot of the cooling pumps Daini. […]
In particular the pumps that cool Unit 1 were destroyed and the diesels for Unit 1 didn’t work. That implies there has to be core damage at Daini Unit 1.
This is one of the big secrets that Tokyo Electric isn’t talking about, is just how damaged is Fukushima Daini. They should also talk about just how damaged Fukushima Daiichi 5 and 6 are but we’re not hearing that either.
But Daini went for a period of time with no way to cool it. It had no diesels. Because the loss of the ultimate heat sink. And now in this earthquake we see an increase in pressure in the containment. These things are related. […] Let’s not just look at Fukushima Daiichi 1, 2, 3, and 4 we need to look at Fukushima Daiichi 5 and 6, what happened to them. And then the Daini units as well. I think Daini 1 is going to have core damage […]
