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 but it was shortly after the earthquake. So it’s certainly a causal effect. […]

At ~11:00 in

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 […]

    TEPCO admitted Dai-ini was badly damaged when they stated that No attempt would be made to
    restart Dai-ini but rather the entire site would be decommissioned as part of the Dai-ichi shutdown.

    I suspect the Dai-ini reactors took enough damage to match TMI in scale but they never got to runaway.

    Quake damage found in Tokai nuclear power station

    Quake damage to turbine blades found at Tokai
    Damage to turbine blades, apparently caused by the March 11th earthquake, has been found at a nuclear power plant in Ibaraki Prefecture, eastern Japan.
 The Tokai Daini plant, about 100 kilometers north of Tokyo, automatically shut down in the quake. The operator of the plant, Japan Atomic Power Company, has been checking the plant closely since May in a regular checkup scheduled to last 6 months.


    It says it discovered friction marks on the blades and other parts of the reactor’s turbines.
 The company believes the damage was caused by the March 11 quake as similar marring had been reported in another plant in Niigata Prefecture in the wake of an earthquake in 2007.
The utility says some parts were also found missing from a device that injects coolant into the reactor. It also discovered cracks in equipment attached to the upper parts of the reactor. 
It says it is investigating whether those defects were also caused by the March quake.
In the giant quake, the Tokai Daini plant lost its outside power sources, and had to rely on emergency generators until regular power returned.
Earlier this month the government nuclear safety body found the level of quake-resistance of the electrical equipment at the plant was below the standard set by power companies.

    We also need information on the 14 Reactors in severe condition.

    Other reactors are all in considerably severe condition” — 14 total; Dai-ni, Onagawa, Tokai — “Extreme situations, though not much has been broadcast”

    Arnie sez: "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."

    SP: You know we always suspected we saw smoke on the videos from fires at Daini.

    Thanks Arnie…watch your back the next time you get invited to Tokyo. They might not even allow you to visit, you old New England agitator. *;-)

    I appreciate your outspoken and honest opinions. Best wishes from Texas for the holidays.

    How do we prove damage to several reactors, sure would go a long way to closing down all nuclear reactors,
    I would be will to donate money to a fund for whistle blowers, our best chance.
    Money talks lets talk, most off us give to charity at this time of year, this is not charity it is survival .
