Tokyo Electric Power Company says the temperature inside the No.2 reactor at the damaged Fukushima Daiichi nuclear power plant has risen again.

[…] to around 71 degrees Celsius from Friday night to Saturday morning. […]

TEPCO says it will continue to monitor the situation closely as it believes the reactor is in a state of cold shutdown. But the utility says it will consider pouring more water in if the temperature rises further.

  • Tepco is taking a risk increasing the pressure of water injection…they are gambling that they can increase the pressure, and hence the flow rate, without damaging the internal hardware, which they cannot see or evaluate. But if they lose their gamble, and their increasing injection pressure damages the hardware, they may end up with little or no ability to cool the part of the corium that is their current focus.

    In other words, they are trying to win political points by staying below 80 celsius, by risking their ability to ultimately win the technical battle.

    TBS/JNN webcam shows green swirling colors inside the “tent” of Reactor 1 and Reactor 2. Looks like little bursts of color,which ebbs and flows from the floor of the reactor area to the roof of both reactors. The colors can be seen at certain screen angles and in copies of the screen captured to JPGs. Sometimes the color is red at one angle, and green at another. Looking UP into the screen at the image of the whiteout areas shows GREENish, Looking down can show the redish hues. The colors seem to be related to the temperature of the reactor. If climbing..more colors..if colder..less area of colors. Absolutely NO idea of how relative this is to the condition of the facility — but maybe a more knowledgable person with nuclear engineering can explain it better. Personal thought is a re-critical event could be possible IF TEPCO can not cool with more water injections. But the water injections..have their own issues..its a no win situation.

    @anne do you see the diagonal object in Reactor 2 which runs from 1/2 up the back wall of the “tent” to the far side (looks like it is cutting off part of the building in a triangle)..any clue what that is? The green swirling looks like its visible, fades..then is seen again..almost in a pattern or “heartbeat.” Do “we have a problem Houston?”
