At 14:02 of 12/12/2012, Tepco stopped the coolant system of SFP in reactor3 to add valves and check clack valves. It will be stopped until 12/18 while Meteorological agency is warning about the possibility of M8.0 after the M7.4 on 12/7/2012.

Tepco states the water temperature increases at 0.16℃/h without coolant system. It would be increased up to 24℃, but still it’s cooler than the safety limit of 65℃.
