Fukushima nuclear plant 2 the pressure container of the machine, it rises to 78.3 degrees
Tokyo Electric Power announced that 12th morning, Fukushima 1st nuclear power plant 2 temperature of pressure container bottom of the machine same day at 10 o’clock in the morning rose in Celsius 78.3 degree. According to Tokyo Electric Power Company, value of this temperature in the December last year later cool temperature stopped state is declared, reaches the highest value.
You call 2 the thermometer of remainder that it is transitive at approximately 35 degrees.
2 temperature of machine pressure container bottom rose entering February, but once it had decreased to approximately 65 degrees by increasing the pouring water quantity for cooling. But, 11th in the afternoon again in Celsius 74.9 degree rise. In the 11th night the pouring water quantity per hour was made 1 ton increasing and the same 14.6 tons. As for Tokyo Electric Power Company, because you cannot see the effect of cooling, you say that modification of the pouring water quantity is examined.

EX-SKF has the press conference details:
[...] TEPCO do not give morning presser on weekends any more, but today is the exception due to the concern over the Reactor 2 RPV. Matsumoto is doing the press conference, instead of the usual junior manager of PR department.
Q: What happens if the temperature here exceeds 80 degrees Celsius?
A: Further increase of water to be injected into the RPV. But the cold shutdown state should take other parameters of the reactor into consideration.
Q: Possible causes?
A: Unstable cooling at the location. Some movement inside RPV of melted fuel, possibly, disturbing the flow of water. We don’t think it’s likely because we haven’t been working near the reactor. Instrument failure is another possibility. [...]
