Another interesting observation from Arnie Gundersen

“Fairewinds analysis of the triple meltdowns at Fukushima Daiichi determined that other Japanese reactor sites were also in jeopardy because their cooling water systems were destroyed by the same tsunami. In this film, Fairewinds provides evidence that cooling systems for 24 out of 37 diesel generators were shut down by the tsunami and that 14 additional nuclear reactors were impacted.”

Important information.

I continue to ponder why the following ECCS did not work:
Reactor Concepts Manual Boiling Water Reactor Systems Boiling Water Reactor (BWR) System, USNRC Technical Training Center

Pp 3-14 “High Pressure Emergency Core Cooling Systems
The high pressure coolant injection (HPCI) system is an independent emergency core cooling system
requiring no auxiliary ac power, plant air systems, or external cooling water systems to perform its
purpose of providing make up water to the reactor vessel for core cooling
under small and intermediate
size loss of coolant accidents. The high pressure coolant injection system can supply make up water to
the reactor vessel from above rated reactor pressure to a reactor pressure below that at which the low
pressure emergency core cooling systems can inject. ” end quote.


When Nader and Abbott published their book which reported serious dangers in the ECCS, containment, multiple reactors at the same site etc, nuclear industry squarely condemned the work.

So the book must have a lot of good information in it. I suppose I should drag it out and have a look at what they wrote in 1975 which drew so much ire from nuclear employed experts.

(and I am not saying Arnie is wrong about the diesel generator coolant loss across multiple reactor sites in Japan in March 2011. Rather, my long standing question is, given the decades long nuclear industry assurance that the ECCS would work (though never tested full scale) and would always work because it was 1. self contained 2. required no external ac power. If it worked, and the Fukushima Diiachi triple reactor containment breach occurred anyway, what was the point of the intense industry effort to design ECCS for reactors over the decades 1960 to 1980? It cost billions of dollars. Would this money have been better spent devising high bandwidth solar cells? I think so. Not as geeky as an ECCS that doesnt work I suppose though. )

I await Ziggy’s assurance that the Japanese are the best in the world, as he said in March 2011 and his assurance that the three now broken reactors had ECCS that did indeed work as designed and that the outcome at Fukushima Diiachi is precisely the parameters he and all the other “experts” were aware of in March 2011, when he and all the other industry seers gave their prognostications.

And if these parameters are indeed fulfilled, then someone had better fess up to the Japanese people. For if what happened and is happening at Fukushima Diiachi is within design expectations for reactors failures (which they said would never, in real terms, happen at the time of deployment) only madmen would have bought the product.

After 5 decades of didactic assurances from nuclear industry, assurances which turned out to be mere sales blurb, it is well and truly time to rub their collective noses in it.

As it turns out they aren’t even expert in the art of diesel engine cooling systems, let alone nuclear reactor cooling. And they say, oh it was the natural disaster. But the legislation and the mandate and the requirement was precisely to ensure reactors survived such. They don’t. They are too feeble and dysfunctional to cope with reality.

The industry will say everything worked as planned, including the ECCS in the three failed and breached reactors. The result is the situation in Japan present day.

Some plan.

Nuclear energy has delayed the advance of energy science.

To boil water in order to make steam to drive turbine, all you need is a fuel capable of producing temperatures in the order of 100 degrees C.

The melting point of uranium fuel is 1132 degrees C. Source:
Pure genius? No.

If all you want to do is boil water, or even create super heated steam, how hot do you need to go?

I thought that it was a requirement for all reactors to have a viable ECCS. Apparently not. If the ECCS didnt work in Japan, the ECCS is not going to work anywhere. You cant blame the quake or the wave. The ECCS is mandated in case of such an event causing loss of coolant. I would have thought, given the official assurances in the 1970s, that the ECCS in every reactor would work reliably when called upon to do so. Apparently not. No mainline media has mentioned it, so I guess its not important. Or to the contrary, if they want to hide a major untruth.

    Great Post!
    This is of huge importance, because as we now know, TEPCO (and the other nuclear “Gangs” have not been forthcoming about the types of damage that the reactors suffered due to the Earth Quake wanting instead to keep the myth alive that the damage was ONLY because of the Tsunami…

    Now the news about the effects of Earth Quakes is beginning to trickle out and once accepted my MSM, it sill spell the end of the Nuclear Energy era!

    I’ve posted this many times since 3/11/11:

    Many now believe that the Quake was the REAL CAUSE of Fukushima’s triple meltdowns, yet the MSM continues to cover over that fact using the Tsunami to protect the Nuclear Industry, because Fukushima PROVED that Nature can destroy any land based nuclear reactor, any place anytime 24/7/365!

    The quake has caused serious damage to all of Japans reactors, that is why they remain off line despite what their Gov’t says…
    because as Fukushima proved, Nature can destroy any land based nuclear reactor, any place anytime 24/7/365!

    With the above known, now consider the ramifications of this:
