Reactor 2 RPV Bottom 91.2 Degrees Celsius (TEPCO Press Conference 11AM, 2/13/2012 11AM)

(UPDATE 2: 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.)

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

(UPDATE: 94.9 degrees Celsius as of noon on February 13, 2012. Instrument failure most likely, the company says.)

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

The temperature at the bottom of Reactor 2 RPV (69H1):

2/13 5:00 89.6
2/13 (missed the time, I think Matsumoto said 10:00) 91.2

It is not responding to the increased amount of water injected (about 18 tonnes/hour). The temperatures at the other two locations (69H2, 3) are going down. Therefore, it is the instrument failure most likely, TEPCO's Matsumoto concludes.

TEPCO will maintain the amount of water injected for the time being. No plan to change the amount for the time being.

Q: The steady rise of temperature like this doesn't seem like instrument failure.
A: We want to investigate whether such "failure" is possible where the temperature rises in small increments.

Many reporters, hardly any questions, and the press conference is over in less than 30 minutes.

Matsumoto said the temperature may change because they are conducting some test of the instrument.

The temperature data is not yet updated on TEPCO's site.

UPDATE: Hourly temperature at Reactor 2 RPV bottom, latest.
