Reactor 2, of the Fukushima Daiichi nuclear plant, continues to see increased temps, despite increased water injection.
At 10:00 hours on the morning of 13 February 2012 (Japan time) Tokyo Electric Power Company reported that the temperature hit 91.2 Celsius (196 Fahrenheit), by noon it was 96.4 C (205.5 F)!
TEPCo officials are hoping the thermometer is defective! If the Reactor 2 hits 100 Celsius it will no longer be in cold shut down, and re-criticality is a possibility.
Two other thermometers are showing temps hovering between 30 to 35 Celsius. However, TEPCo has just revealed there are three other thermometers, positioned about four feet lower down on the reactor, and they show temps dropping. It sounds like all their thermometers are faulty!
TEPCo says all their eyes are on Reactor 2, and they’re working to get an accurate temp reading. Reactor 2 is the only reactor, that went critical after the 11 March 2011 quake and tsunami, that did not explode. Reactors 1, 3 and 4 exploded.
