Title: New Large Debris Found Inside Unit 1 Containment
Source: SimplyInfo
Date: October 17th, 2012
Videos released by TEPCO yesterday included a scope investigation underwater. The water itself was surprisingly clear with a small layer of tan sediment and small white floaters when the water was agitated near the walls or floor of containment. What was even more interesting was the variety of large debris found inside unit 1′s containment underwater. [...]
There is a considerable amount of large debris including structural steel, steel pieces and what may be concrete or thick steel. These findings further confirm damage inside containment.

The jagged edge large debris look like some spalled concrete.
The metal pieces are likely bits off of light fixtures, brackets, etc. In some of the robot pictures of the upper floors there are small metal bits laying around.

The first thing you realize, while cruising around Containment1 is that little melted fuel remains. No light flashes of radiation hitting the camera. No roiling or boiling of the water. In fact, the camera and instruments are obviously the only thing that has disturbed the sediments here in a long time. The place is quite still. There used to be 50 tons of corium sitting on the bottom of Containment1, at a cool 3,500 degrees F, according to Gundersen. It is clear to everyone that the Corium is no longer anywhere near the settled sediments on the bottom of Containment1. Other than the whisp of steam in the air, there is little evidence that this "contaimnent vessel" has ever been hot. TEPCO, we keep asking you to identify where Coriums1,2,&3 are. TEPCO, where is the corium?
Meanwhile, the "white floaters" may be fragments of bacteria mats that have taken over the waters throughout the Fukushima ruins. This life form may someday inherit the Pacific Ocean bottom, where the radioactive debris of Fukushima settle, killing off most other life forms in a mostly sterilized biosphere.

i think the corium of units 1+3 have been blewn into the air in huge explosions as we could see then…

Why is it people make soo many assumptions from a LACK of information and then post as if these supositions are fact when most of what they are using for information has already been proven to be false. They just spread that much more false informetiomn.

1. Because LACK of information and data is all we have to work with.
2. Supposition and speculation are not a bad things.
Fury says…
"…NO melted fuel escaped the reactors."
(btw – This is NOT a FACT, it's just another supposition.)
Then, where did it go and how did it get there??
Report Comment
Phillip, I don't believe that Gunderson ever said that the fuel was actually at the bottom of the containment, only that there MIGHT be that much there IF the stuff had melted through. And later he said everything indicated that nothing had bmelted ground through any reactor vessels. Don't change arund what you read. The teason there is no radiation to speak of in the bottom is because the fuel was NEVER there, if it was there would still be some left, it couldn't all have dissolved out. And if it melted through into the ground , why is the bottom still in place and holding over 5 feet of water? See NO melted fuel escaped the reactors. The only fuel that did was dissolved in seawater.
Report Comment
Fury, Actually, Gundersen pointed out that the Mark has many pipes leading out of the reactor at the bottom and that the fuel had many holes to leave the reactor when the pipes broke with the earthquake on Mar 11.
And there are articles by nuclear scientists beside Gundersen who predicted the rate of flow of the corium below all containment into the ground below.
The amazingly large tonnage of spent fuel rods at Fukushima has also been published. The main reason that there are so few reactors left operating today, 2 maybe, is that the rest were damaged so severely by the Mar.11 earthquake and subsequent aftershocks, and are not salvageable.

"• I think the real key here is it doesn’t matter
• The nuclear core is leaking through containment anyway
• It doesn’t have to melt into groundwater
• There are so many leaks in containment it is leaking into groundwater and ocean anyway
• Therefore the plutonium and the cesium and the strontium that’s in the fuel has run throughout the entire complex anyway and is getting in the groundwater
• China syndrome doesn’t matter because the groundwater is already contaminated because containment is leaking elsewhere.
• Containment is so radioactive there is no way of determining where that nuclear core really is…"

as for water levels in the containment, presence of water there in no way proves that the containmnet is intact. fluid levels depend mainly on the water table level outside if the containment has a big hole.

Ah yes, in praise of objective observations, calm deductive reasoning and wise public policy outcomes!
Trouble is that public policy has been hijacked by K Street, and what we actually get is a vicious defense of the status quo at any cost, even if current global energy policy puts mankind on a collision course with a dying biosphere ("Super Greenhouse" and escaped stockpiles of existing spent fuel is not a world that can maintain civilization, and may well pose a risk to the future of our species. Sic transit gloria.)
So ordinary people are entitled to be FURY-ous about the direction we are headed. It is about elites maintaining their power as the rest of us go to hell in a bucket.
Oh and BTW, I agree with you about Unit 1. On the available evidence it is possible all the disrupted fuel assemblies remain inside the RPV. OTOH, if radiation levels were not sky-high, we could have taken the lid off of the RPV and taken a look-see, so what the heck is the delay all about? MAYBE inconvenient truths are being withheld from release, by the Nuclear Village power brokers.
Unit 1 had all the appearance of a hydrogen explosion, unlike Unit 3, whose fuel might have been dispersed into seawater by several routes. How did massive contamination get onto the DECK of the USS Ronald Reagan if it was only dispersed by being "dissolved in seawater"?

I have to login to cry foul. Your not saying that plain ole hydrogen can blow a reactor containment building to smithereens are you? I don't think anybody here believes uncooled fuel can stay in its correct geometry and not burn or melt out of containment (depending on oxygen of course). An expert in nuclear fuel has confirmed that uranium does not act like alka setzer under water. It will heat itself up and whatever it comes into contact with. Why is it hard to believe that the uncool fuel inside the rods reached 4,000 degrees F. within hours of LOC? Melted down and gained another 4,000 degrees within its larger mass at the bottom of the sfp or rcv.

@Anne that is a good question. Someone might want to figure out where the corium has traveled in the oceans…before it meets up with the BP spill high saturation areas in the Gulf waters near Lousiana.
The scientists out there can explain what happens when the benzene from the BP oil spill mixes with the corium and cesium from Fukushima and meets up with the highly flammable toxins in the Louisiana rivers that are currently dumping into the Gulf via the Mississippi river.
If this mixture is sparked in any serious way-including lightning strikes, there is going be a serious problem.

Disasters can only be hidden for so long in this fast moving information age. So..radiation sickness/illness, fires/explosions, poisoning from chemicals..it will show up..and people will tell others. Unfortunately..the "after the fact" effect is in place..so no help or protection provided by governments who are trying desperately to HIDE their failures. After elections, after major events which suddenly occur..we will finally find out "ground truth"..as opposed to the "story line." Truth comes out in drips and drops..disseminated slowing to hide the horror of the various situations…Guidance to officials is probably given in various government "control the masses with media" instruction manuals and training classes…

Hi Anne: Ok , even the engineers that have said that the "corium", which is a mixture of fuel and all the other metals that are present in a reactor wether it has solidified or not, have not been present on site and are presuming only from simulations that have not been proven , and from a minimal amount of information. Instead look at what the videos show and do not show. Don't look at just one thing trying to find a specific answer. You might find one that is not there. Multiple 4" holes, yes, for the piping and sensors. If they are leaking from there it will be fairly easy to stop when the radiation goes down. Melted fuel underground would be easily detectable as being there by radiation readings. It's not there.Why do you think they are trying to find the Exact position of the fuel? IE how much is actually melted and did Any leave the reactor vessels. They need to know wether there are any large "chunks" of material outside of the reactor vessel. If there is it will take much longer to clean up because of the radiation hazard. If not then it would be much easier and safer to simply pump or vacuum out the dust and dissolved materials. But they have to be surebefore anyone goes in. The simulations show that the core could have melted through in this type of reactor, Old simulations. Not enough info to do new more accurate ones till this is over. The problem is the readings and info they have been getting do NOT shoe a melt through…

@Fury
Which engineers from which facilities?
Where is their written documentation located?
If I want to examine videos I will ask the expert Nuck to please come here and look.
If you're saying corium is not present then show the corresponding recent data published.
What resource are you using to state that corium can be easily found and if that is the case why can't a travel path be found?
If it is not there, where is it? Based on it's degradation time and constant outflow nothing has yet dissipated.
Both "chunks" of material and "mixtures of fuel" with corium are still heat, and flammable, sources of corium.
What mechanism will be used to pump or vacuum these particulates out and when is the plan for such action as written by either Tepco or the government?
What method of analysis are you using to assess the simulations? You show no data.

as far as how Tepco will clean out the debris I have no idea. That will be up to the engineers on site. I believe I said that was just one way of doing this. they might wait a couple years and let more radiation dissipate and then go in and scrape it out by hand, but I think not. I am not there so I don't know for sure what I would do.
Report Comment
Three Mile Island did not follow the sim's. No melt through, even though according to previous sim's it should have. It didn't. The reason a travel path can't be found is because there isn't one.!! v As Dr Gunderson said, I believe shortly BEFORE tha latest video came out, "" I think what most likely happened is that the core melted to the bottom of the reactor vessel and solidified there and is sealing off the bottom of the reactor. "" This is from memory a couple days old so may not be an EXACT quote. Then the video came out and does not show or in ANY way indicate any core parts or material in the containment vessel. All the readings indicate the radioactive material is ABOVE the containment in the reactr vessel.
