Emergency mail from Tepco.The heating gauge of the bottom of reactor2 showed temperature increase. At 17:00 of 2/11/2012, it was 69.5℃. 6 hours later, at 23:00, it was 74.9℃ (+5.4℃) Tepco decided to increase the water amount to inject.

Nikkei translated by Babelfish (Emphasis Added):

2 the pressure container of the machine, temporarily in 74.9 degrees the re-rise Fukushima nuclear plant; The pouring water quantity to the reactor it increases

Tokyo Electric Power announced that 12th early dawn, Fukushima 1st nuclear power plant 2 temperature of pressure container bottom of the machine 11th in the afternoon in 11 occasionally points rose in Celsius 74.9 degree. 12th morning in 0 occasionally points 71.1 degrees. For cooling 11th 10:45 PM in, the pouring water quantity to the reactor per hour was made 1 ton increasing and the same 14.6 tons. You call the thermometer of the remaining 2 place that it is transitive at 35 degrees. [...]

It was declared to satisfy cool temperature stopped state in the December last year, temperature bottom has had to have reached 100 degrees or less. When of error of the thermometer is thought approximately 20 degrees, 80 degrees or less becomes standard.
