Reactor 2 RPV Bottom Temperature: 94.9 Degrees Celsius at Noon, 2/13/2012

(UPDATE: Instrument deemed broken, as the temperature at 5PM on February 13, 2012 is 275.9 degrees Celsius. It was as high as 342 degrees before 3PM. See my new post.)

==========================================

10:00 91.2
11:00 93.7 (from TEPCO's Plant Parameter, 2/13/2012 noon)
12:00 94.9 (Mainichi Shinbun, 2/13/2012, last update 12:57PM)

Mainichi does not have much to say beyond what I've already reported in the posts, here and here. Most certainly it is the instrument failure, TEPCO, NISA say.

The measurement of the temperature at noon must have been disclosed during the press conference held by the Nuclear and Industrial Safety Agency after the TEPCO's press conference. There was no mention of the temperature at noon, as the press conference was brief and was over by 11:30AM.

There are nuclear engineers and experts who doubt this foregone conclusion of "instrument failure". I will write a post about it later once I understand it myself.
