Fukushima Daini Unit 1 had pressure increase after quake, before tsunami — Gundersen: “They should also talk about just how damaged Fukushima Daiichi 5 and 6 are but we’re not hearing that either” (VIDEO)

Fairewinds Podcast, Dec. 9, 2012:

At ~5:00 in

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 . . . → Read More: Fukushima Daini Unit 1 had pressure increase after quake, before tsunami — Gundersen: “They should also talk about just how damaged Fukushima Daiichi 5 and 6 are but we’re not hearing that either” (VIDEO)
