#Fukushima I Nuke Plant Reactor 2: Temperature Gauges Go Haywire, EX-SKF, Nov. 29, 2011:

Some of the temperature gauges for the Reactor 2 Suppression Chamber and the Containment Vessel seem to be malfunctioning.

In each case, only one gauge out of several seems to be affected. Cause unknown, according to TEPCO. Countermeasures: closer monitoring of gauges. [...]

Some terminal feeling at Fuku-I, where all they could do is to monitor the gauges.

TEPCO’s press handout on November 28 (English);Excerpts from EX-SKF’s breakdown of the handout:

Gas temperature of Suppression Chamber of Unit 2

・11/26 17:00, read 52.7℃, but at 11:00 pm on the day we confirmed that it read “Overscaled” (digital recorder).

・11/27 5:00, it read 102.6℃. Though the readings were not stable, as there were no significant changes or variations in the temperatures of the same types of 2 thermometers and the pool water in Suppression Chamber, we have been investigating the causes for this event [...]

Temperature inside the Primary Containment Vessel (Drywell) of Unit 2 (base line temperature of the air conditioning unit, local cooling equipment)

・11/27 5:00, read 78.2℃

・11/27 6:50, it was confirmed that it read approximately 84 , increasing in a staircase pattern. [...]

Later we inspected the instrument but got no data indicating malfunction, and the readings after the inspection are not different from those before [...]
