Thermometers of reactor 2 indicate abnormal transition of temperature

Following up this article..Possible recriticality in reactor2

From the evening of 5/28/2012 (JST), 4 thermometers of reactor 2 have been showing abnormal temperature transition.

Tepco states recriticality is not going on, and the transition is random, probably those thermometers are out of order again.

However, 2 of them are about supply air D/W (O.P. (Onahama peil)= 12.150m), 2 are about return air drywell (O.P. = 10.750m)

and the thermometers of each pair show the same trend.

Though the trends are becoming stable, it is not known what happened in PCV, but those 2 pairs of the thermometers are beside the pedestal, where Tepco assumes the nuclear fuel remains.
