The water in the SC is up to 10 Sv/h. No wonder the dosimeter then failed.

The radiation dose measured in the Torus Room was 19.5 - 10,300mSv/h. However, the dosimeter seems to have failed.

And the sediment at the bottom looks rather orange...dripping lava/corium?

From pdf:

3. Radiation dose of the accumulated water The radiation dose measured in the Torus Room was 19.5 - 10,300mSv/h. However, the dosimeter seems to have failed as it indicated order values of 10^8 -10^9mSv/h during the measurement and the values did not change until the dosimeter was brought back up.

So they are really telling us it measured as expected with dose increasing to a new range as they measured closer and closer to the floor of the building.

Just before water 10,000mSv hour

An expected drop to 8000mSv an hour on water surface as some neutron soak occurs, gamma still coming through though.

80cm below surface a further decrease to 3550mSv

100cm lower a decrease to 2,770mSv

Then at a further meter of drop , roughly a meter because they are measuring above one of the most radioactive places in the world using a camera cable as a tape measure; we get 'Indicated order values of 10^8-10^9'.

10^8 is 29,809 mSv/hour
10^9 is 81,030 mSv/hour

Mathematically that works out close with expected dose rates and square law from source. A huge amount of steam, corium and other nasties have vented into torus and most of the lower building. But why on earth would the reading jump below OP2200 after 2,770mSv reading?

Part will be because the torus itself partially shielded the probe from line of sight measurement of the most likely path of corium. Draw a straight line from below the centre of the pedestal (and centre of reactor) where melt occured through, as they hit OP1200, the radiation spikes exactly as you'd expect.
Furthermore corium and nuclides which have settled to the floor will be immensely radioactive. So either the pedestal is gone, a possibility in this completely under-designed containment, or just like Chernobyl, fuel has leaked down the suppression pipes into the bottom of the torus, then to the floor and beyond, plus whatever came from the pedestal.

Put this together to further illustrate what I'm rambling on about. This is the measurement map transposed over R1 blueprints. Green line is from reactor/pedestal centre line.

Much respect to the brave workers who measured this.

Catching up tonight, you all have more brilliance in this thread than a diamond factory!

Is this already upon us?

Reactor No. 1: 50 tons of nuclear fuel
• Reactor No. 2: 81 tons
• Reactor No. 3: 88 tons

was 219 tons of radioactive material released upon the entire earth population on march 11? Or am missing something?

Biggest dirty bomb in the history of man. And they worry about proliferation? Already happened 500+ times world wide at each reactor.

What is left of those other pools, 1, 2, and 3?

R1-3 write off 100% of that fuel. No water for them good part of a day = 100% melt. To say some fuel magically wouldn't melt without water for an extended period, in a neutron storm, is complete bull#. Plant evacuated during this time as *airborne* radiation levels exceeded 400mSv and that's what they released to public..

SFP4 Ran dry multiple times, fires admitted, captured on video and melts have occurred without a doubt. They specifically focused on filling this up as it's such a risk. My guess is at best case up to 15% of that fuel is now nuclear potpourri. A reactor load or two. Not all has to be concentrated in one place and melting through the pool though. Hydrogen bubbles seen coming from the pool.
SFP3 well, we have seen concrete and steel debris all through the pool so likely some geometry failure, partial melts and releases there. Up to 5% or more damage, hydrogen bubbles also seen coming from the pool. No glows like R4.
SFP2 have not seen a shot of that I'm aware of. Likely intact.
SFP1 or top of R1 is about as rare as a shot of the north west wall R4. Considering collapsed roof, some geometry failure possible, similar to R3 damage.

UC would be more likely highly enriched plutonium and thus more unstable because of that. They are still worried Chernobyl could go up, so I guess the UC would be even worse. Zworld did a great piece on instability and phases of plutonium through its lifetime and various enrichments. Theredneck had great explainations about plutonium/corium reactions and cyclic criticalities in the earlier posts.

Overall, I'm quite amazed northern hemisphere is still producing mostly normal children. Statistical illness, death rates, birth problems and disease trends are no doubt telling a different story.

## Unit 4: SFP Cooling Restarted

TEPCO resumes cooling Fukushima Daiichi No. 4 reactor fuel pool TOKYO, July 1, Kyodo Tokyo Electric Power Co. said Sunday it has resumed cooling the spent fuel pool of the crippled Fukushima Daiichi power plant's No. 4 reactor following emergency repair work after the cooling system shut down on Saturday. The water temperature of the pool had risen to 42.9 C when the utility known as TEPCO turned the cooling system back on shortly after 3 p.m., compared with 33.3 C at the time of the shutdown on Saturday morning. TEPCO had feared that the temperature could reach 65 C, the upper limit designated in safety regulations.

The nitrogen gas injection into RPV is being continuously conducted at the amount of approx. 16 m3/h,

- Purple Chive

I think the 'balance' referred to is between the amount of nitrogen gas injected and the amount of PCV air exhausted by the PCV gas treatment system. They would want to exhaust roughly the same volume of gas from the reactor as the volume they inject. Unlike other adjustments we've seen, this recent reduction of nitrogen injection through the PCV has been done without a corresponding increase of injection through the RPV. So on the face of it, I'd think it must mean, that the exhaust capacity of the PCV gas treatment system for some reason has been reduced, necessitating a reduction of the overall injection rate to keep the balance.

GR's analysis is spot on. The only thing I would add is that it's important to remember that the UC is still in the theory stage and may never be proven fact. That is why I chose to write a fiction book instead of a report. That way I can connect dots not otherwise proveable. Plus Im forced to use a fair amount of Tepco, NRC, IAEA, MEXT etc data which is of course fictitious to begin with.

But if it does exist, and it contains a large supply of enriched plutonium and a large supply of tritium (for fusion part of explosion) then we need to pray every day that the initial blast buried it and its deep enough and saturated in groundwater enough to never be a problem. We have to consider this the outcome because anything else is too extreme a thought.

Neysa, others (AC, PC ?) have spotted this plume before. It comes out at night I believe from R2, which indicates some kind of venting possibly. Similar plumes have been spotted coming from R3 and R4, the R3/R4 exhaust stack, the 4stack south of R4 and the back of the southend. These almost always occur at night and often they start up just as a fog is rolling in.

Good eye. Thanks for staying on top of this.

And how comforting is this. Its a fairly significant rise that seems to coincide with the pulling of the control rods though not sure of timing though. This spike may have started before the pulling of the rods. Early venting of system? If someone knows the exact time of startup that would be easy enough to overlap with this graph.

At this point Id start in with THE WHOLE WORLD IS WATCHING....THE WHOLE WORLD IS WATCHING

But unfortunately, thanks to Murdoch and the rest of the right wingnuts, the whole world isnt watching. Instead we have Storage Wars, Mob Wives, a bunch of sporting events, the CBS, NBC and ABC Evening News Disinformation Campaign.......lets see what else....damn....thats about it.

I must confess, since switching to google chrome, which doesn't allow for Winamp to operate from it, I havent been watching the cam at all and depend now on PC and Nucklechen and others for scenes to watch.

Madder - my apologies...but what? Your response still leaves me befuddled. Please remove all trepidation when posting on this thread. I've seen your work on PF, and it is admirable.

What is your gut feeling that there appears to be absolutely no effect on temps, pressure or hydrogen level in Unit 3 after shutting nitrogren injection into the PCV to Zero for four days now.

When nitrogen injection into Unit 2 stopped a few weeks ago - pressure and hydrogen levels reacted detrimentally and immediately. This does not appear to be happening with Unit 3.

Why?

With much respect,

Question Neysa - what brings you to this thread?

It's a combination of things. First of all, I don't expect to get any factual information regarding Fukushima, from the MSM. This ongoing event has very serious consequences for ALL citizens of this planet. Anyone with a pulse should be following this closely.
I feel safer trusting the regular contributors of this thread than I do my own or the Japanese government when it comes to Fuku. How sad is that?
I am one of those weirdos that actually feel better when I know what the hell is going on. Go figure...
Drives me crazy when people just trust what they hear and trust those in charge to keep them safe.

Better for me if I gather all available info and make my own decisions.

Why do you ask?

it may actually be good news,, if the leak/hole/crack/seam/ is sealed,,
shut off the nitrogen,,everything stable,,,ie no pressure drop or temp rise,,
and circulation of cooling is stable,,circulation pumps working,,running,,
then everything is ok.
now what is NOT factuall about the above.
