MOX Fueled Reactor No. 3 temperature rising — Pumping water may be ‘insufficient’

Watch as reactor #3 overheats in real time with this updating chart:

http://atmc.jp/plant/temperature/?n=3

---------
NHK, May 10, 2011:

says the temperature of the plant’s Number 3 reactor has been rising this month, and that work to pump water to cool the reactor may be insufficient.

The company says it is installing new pipes at the reactor and hopes to start pumping water through them on Thursday.

“Tokyo Electric reported a sharp rise in temperature at the nearby Reactor 3. It was at 202 degrees Celcius early Sunday, up 40 degrees in less than a day” -Voice of America, May 8, 2011

1. maybe to much fuel has piled up in the bottom

top layer can only be cooled then.. (i dunno just throwing ideas out)

3. If it's coagulated in some amount that sounds about right

This one has the plutonium mix fuel that melts at a lower level so one can only imagine the state it is in and how very undesirable it would be to have a large release from #3

2. This sounds pretty ominous.

I wonder if they are going to build another containment building around the containment building? I would wonder how the current structure is holding up, given the dire circumstances..

4. I wonder also, they hardly mentioned the No.3 spent fuel pool

until lately, not sure of the impact of that mess on the reactor itself.

All of it must add up to very high levels of radioactivity in that zone.

7. Its because the #3 fuel pool doesnt exist anymore

its spread over half the prefecture, they dont tell you that either. Oh yea, and the surrounding ground out past the exlusion zone has 4x per square meter the readings at Chernoble (sp?)

5. Problem with encasement is that they can't easily dig below - water table is just a meter or two.

They'd have to trench and pump to build a drywell - not easy on this scale, even near an open-air radiation emitter.
