There’s been confirmation in the press in the last few days that Daiichi #1 did indeed suffer a partial meltdown. Kevin was right
From Kevin[10:38 am Saturday 12th March]:
“Those images of the reactor containment building post the explosion say it all. I think it’s eventually going to turn out to be the case that they’ve had a partial core melt.”
The Telegraph reported on Thursday:
Engineers from the Tokyo Electric Power company (Tepco) entered the No.1 reactor at the end of last week for the first time and saw the top five feet or so of the core’s 13ft-long fuel rods had been exposed to the air and melted down.
Previously, Tepco believed that the core of the reactor was submerged in enough water to keep it stable and that only 55 per cent of the core had been damaged.
Now the company is worried that the molten pool of radioactive fuel may have burned a hole through the bottom of the containment vessel, causing water to leak. link to article…
