Fukushma: CORE ON THE FLOOR?

http://ex-skf.blogspot.com/

Blogger Ex-Skf translates an interview. First I provide exceprts from his introduction in yellow and then from his translation in green. Please read the entire story at his site linked above. His reporting has been excellent.

Ex-SKF explains what he saw:
“Michio Ishikawa of the Japan Nuclear Technology Institute on the situation at Fukushima I Nuke Plant, as he appeared on Asahi TV on April 29.


“I watched the segment (video No.2 out of 11) where he discussed the situation at Fukushima I Nuke Plant, particularly about the condition of the reactor core….”

Ex-SKF translates:

“I believe the fuel rods are completely melted. They may already have escaped the pressure vessel. Yes, they say 55% or 30%, but I believe they are all melted down. When the fuel rods melt, they melt from the middle part on down.
(Showing the diagram) "I think the temperature inside the melted core is 2000 degrees to 2000 and several hundred degrees Celsius. A crust has formed on the surface where the water hits. Decay heat is 2000 to 3000 kilowatts, and through the cracks on the crust the radioactive materials (mostly noble gas and iodine) are escaping into the air.


"Volatile gas has almost all escaped from the reactor by now.
"The water [inside the pressure vessel] is highly contaminated with uranium, plutonium, cesium, cobalt, in the concentration we've never seen before.


"My old colleague contacted me and shared his calculation with me. At the decay heat of 2000 kilowatt... There's a substance called cobalt 60. Highly radioactive, needs 1 to 1.5 meter thick shields. It kills people at 1000 curies. He calculated that there are 10 million curies of cobalt-60 in the reactor core. If 10% of cobalt-60 in the core dissolve into water, it's 1 million curies."


…."They (TEPCO) want to circulate this highly contaminated water to cool the reactor core. Even if they are able to set up the circulation system, it will be a very difficult task to shield the radiation. It will be a very difficult work to build the system, but it has to be done.


"It is imperative to know the current condition of the reactor cores. It is my assumption [that the cores have melted], but wait one day, and we have water more contaminated with radioactive materials. This is a war, and we need to build a "bridgehead" at the reactor itself instead of fooling around with the turbine buildings or transporting contaminated water."

I INTERPRET THIS AS MEANING CORE ON THE FLOOR. WHAT NEXT? WILL THERE BE MORE LARGE EXPLOSIONS?????
