Yep. Cold Shutdown is no more. There was a rumor that they were considering distributing Iodide tablets. They had a quake shake up the site on the 9th. That always causes the temperatures to rise up a little bit. Shake and bake. So it was inevitable.

The real concern is what the temperature is down where the main mass of melted corium is located. If this temperature reading near the bottom of the RPV, is due to heat from the corium sinking down into the concrete base. Then the middle game crisis has begun. And they do not have enough water to stop that.

Tepco has been showing some very misleading diagrams on the location of the temp sensors. They claim that two still reading low are at the same height in the RPV as the one reading high. Therefore the one reading high is faulty. That is not the diagram I saw about a week ago when they first starting having this problem. The high reading sensor was located low and the low reading temp sensors were higher up in the RPV.

At this point in time, watch their actions again, not their words. Especially if they distribute Iodide tablets and start dumping mass quantities of boric acid into the #2 hole in the ground.

And from someone who trouble shooted complex electro mechanical digital gear for over 10 years, never assume the sensors with readings you like, are the functional ones. Yes, the odds say they are, but the odds can work against you.
