Umm... isn't this "RO concentrate" with its 2 Sv/h beta and 22 mSv/h gamma surface level actually "[pre-]purified water" and "contaminated solution" at the same time, too?
See here for example.
Maybe this is to confuse people?
Actual "SARRY concentrate" slurry is much more radioactive...
As Astronuc said, underground nuclear plants are much more expensive to build.
And they aren't much safer.
Crooked Swiss Lucens mountain nuclear plant made groundwater in its vicinity unusable because of high radioactive contamination.
Soviet Union had a number of weapon plutonium reactors...
I'd be careful attributing smog problems to Isfahan plant.
At this annual season pollution seems to be at its high, see http://www.presstv.ir/detail/2012/12/04/276119/tehran-air-pollution-shud-down-schools-offices/.
As Borek explained, UF6 forms hydrofluoric acid, which is probably even...

Please take opportunity to vote for tsutsuji on this https://www.physicsforums.com/showthread.php?t=656505.
Thanks!
P.S.:
You also could vote for Jim Hardy. But, I believe that Old Jim probably will be okay with tsutsuji being elected...
According to water condensation visible in penetration and chamber fixture there probably was at least some moisture in the containment atmosphere.
Could visible "steaming" and condensation have been caused by (possibly relatively cold) nitrogen gas injection?
But, why didn it rain cats and...
Indeed, how rotten must this nuclear plant look inside now, if immediate photos after discovery already remind of scrap metals yard.
See here for images!
"The obstruction is inferred to be inside the RPV."
This is very interesting.
Let's remember how RPVsapparently fail.
Look at this...
Off-topic (sorry):
I logged in and read the following ad:
May I ask why tsutsuji has not yet been awarded Mentor status?
IMHO he deserves it. May I suggest him as a Mentor candidate?
(Thank you tsutsuji for your great contributions)
Edit:
I'd be curious, too, how much all that restricted...
Reinforced structures, gas lines and all this don't really matter in an exclusion zone, I guess.
And, how much is the genetic degenerative damage to be valued? Is genetic health of later generations a "priority" at all?
If you could ask your descendants seven generations later, they might...
Dear NUCENG, thank you for reply!
If I understand you correctly, published Tepco data only reveals high radioactivity in torus room, but not where it is from.
Your explanation sounds really convincing that there is something dangerous in torus, torus vents or nearby.
But, another thing I don't...
Why then radiation increases strongly when approaching water?
Doesn't this indicate water surface emitting high radiation?
Sadly shielding obstacles like walking girders aren't shown in Tepco presentation chapter 3 to help explain radiation measurements. They are only indicated in chapter 2.
If...
There is groundwater inflow and outflow in basements.
Just helping disposal of radionuclides dissolved in basement water by slowly diluting them into ocean via groundwater.
Proceeding in such manner is helpful reducing storage tank hassles.
Good old Tepco already did some necessary...
Tepco is innocent.
The whole thing is haunted.
Even containment equipment hatch doors swing open and close at will.
Sands used for construction is usually washed in water before usage to avoid soluble and organic contents.
So it is cement salts and/or seawater salts.
Quantity indicates...

First observation. Floor 5 has been lifted up.

Thus bars carrying floor 5 must have severed a little bit from pillars/walls and displaced slightly.

These posts made me think of a scenario.
Readings were manually taken in intervals, yes?
Then it would be unlikely that explosion pressure/vacuum spike was recorded, right?
Could we then actually really exclude existence of such a spike?
And now my questions:
Could there have been a...
Seems correct.
Every TEPCO Daiichi plant status report contains this passage:
Simply check latest Tepco News to verify.
However this doesn't exclude other water or additives (boron) potentially being added to cooling water.
Let's praise TEPCO for wise decision to isolate both basements...
