(7,768 posts)One of the three thermometers at the bottom of the Reactor 2 Pressure Vessel that had been trending in the upper 60s started to rise again in the evening of February 11.
In response, TEPCO has increased the amount of water being injected into the RPV to 14.6 tonnes per hour.
As of 11PM on February 11, the thermometer showed 74.9 degrees Celsius.
The amount of water being injected into the Reactor 2 RPV now is the highest ever since March 11, 2011.
They don't KNOW why the temperature is rising.
Cold Shutdown, eh?

(7,768 posts)The Ministry of the Environment announced on February 10 that radioactive cesium 18 times the national safety limit [40 becquerels/kg] was detected in the firewood from southern Miyagi. The ministry had been conducting the test of firewood and the ashes from burning the firewood in southern Miyagi for radioactive materials.
Radioactive cesium 7 times the national safety limit [8000 becquerels/kg] was detected from the ashes.
On receiving the results, the Miyagi prefectural government is calling the residents not to use firewood for baths and stoves, and to keep the ashes in bags and store them.
And contrary to popular belief in Japan, a researcher at Tokyo University of Agriculture says that radioactive cesium has penetrated deep inside the wood. So, even if the bark is stripped off the firewood, radioactive cesium is still there.
