Well, having just read the IAEA 'Glossary', they don't seem to have a word for it. It doesn't even mention 'meltdown'.

The best they can come up with is 'INES level 7 (major accident)

The question is 'Has it actually reached the water table?'

That glossary is a good find.

I guess that the inspection well drilled 40m from the sea wall is TEPCO's means of taking samples from below the water table.

I don't know what rate of migration of soluble radionuclides one should expect from the corium sink hole to the test well about a 100 yards away to seaward. I suspect that TEPCO don't know either. I guess it will be strongly dependent on local geology.

Yep. I suppose the geology of Japan, and water table, ect. will be under quite a lot of scrutiny in the near future. If it all tends to flow towards the Pacific it won't be 'too much of an issue', but if it contaminates the surrounding area of Japan's, and possibly Tokyo's, water supply the consequences will be......well, how long will it take them to devise suitable water treatment plants?

Geology of Fukushima, where might the missing coriums be hiding?

EDIT: The above article suggests that groundwater under the plant will flow into the Pacific, rather than inland under Japan, which is good news for the Japanese.

I've not yet finished reading this next thread yet,

The recent observation of increasing radioactivity in the test well downhill from the reactor removes some of the uncertainties in the geological report. We know that radionuclides are migrating through the aquifer.

'Iron-hearted' manager in charge of ending Fukushima nuclear crisis - AJW by The Asahi Shimbun -

Clearly a PR initiative aimed at restoring public and investor confidence in Japan's nuclear industry, by giving the impression that something effective and remedial can indeed be done now at last they have the right man to do it. Iron Man!

More urgently, TEPCO will be wiped out financially if it can't get authority soon to re-start the unaffected reactors that it operates at other sites. The last thing it needs is more bad news from Fukushima 1.

Iron Man will push back the molten corium flow with his bare hands!

Japanese Government Approves Revival Plan For Owner Of Fukushima Nuclear Power Plant

With Iron Man now commanding the workforce of homeless people provided by the gangsters with whom TEPCO does business, (as we learned a few weeks ago) how can the great 'revival plan' go wrong?

Might actually work, the melting point of iron is considerably higher than that of uranium.

The hollywood angle is fun:

Archeologists (from the far future) dig around a very old and big fortified building. Finally they unearth an entrance. There is an ancient writing on the wall "Do not enter or you will be doomed"

Could be Windscale, Tchernobyl or Fukushima.

No joke! TEPCO sometimes claim that the mess will be cleared up in 30+ years - and sometimes in 40+ years - which shows that they're making it up as they go along. What these figures mean in reality is that the problem is being left as a lethal legacy for the next generation, when today's corporate and political actors will have gone from the stage, and cannot be held responsible when the forty years is up with no solution yet in sight. (The highly political dimension - distortion - of these time-to-clean-up estimates is echoed in exactly the same "30+" and "40+" years figures given in the last deacde for Windscale's 'final decomissioning', though its disaster happened more than half a century before the Fukushima meltdowns.)
