It seems as if they cannot control the temperature of this pile of rubble. Is there a chance that it will reach criticality? What happens then?

in view of the margin of error of thermometers, according to TEPCO officials.

These guys need a very wide margin of error.

This is from today's newsfeed at Atomic Power Review:

"Fukushima Daiichi No. 2 temperature update

This writer's assumption of February 7 seems now confirmed by TEPCO, who are now saying that the high-reading instrument near the bottom of the reactor vessel at their 1F-2 plant is likely failed. The detector has failed a resistance check performed by TEPCO, meaning that the indication is confirmed incorrect.

It is thus safe to disregard this one outlier in terms of temperature readings at 1F-2 and continue to consider the state as announced previously by TEPCO and the Japanese government as essentially 'cold shutdown.'"

Basically confirmation that the instrument has failed and is giving false readings. I called it as well. So much for the "uncontrolled criticality" fearmongers, who have been wrong all along.
