Chris Canine has 15 years experience as a Health Physics Technician, Chemist and Radiation Safety Instructor. He has worked at over 20 plants throughout the United States, Japan and Mexico — including Fukushima #1 and #2 in the late 1970′s.
Tepco is basically saying that the refueling floor is still too radioactively hot for any human to enter. There was no fire in that spent fuel pool, and we never heard that it was like unit #3 and blew the lid off the pressure vessel. So why are radiation levels so high? During normal operations there is little radiation on the refueling floor because there is really nothing there. The fuel in the pool is under water with no dose on the surface, and the reactor is buried under cement and steel.
My best guess is that the hydrogen explosion had to blow the lid off this reactor also. With radioactive gasses and particulates coming out of the reactor the cover was put on the building to limit the releases out onto the site. But as the cover kept in a lot of this radioactive material the refueling floor is so contaminated that it is no longer a place where humans can work or even walk through.
Find the answer why they put a cover on only this building and that will tell you the condition of this unit.
This whole fiasco is some sort of giant jigsaw puzzle. Tepco will not tell the truth or explain what is really going on so you need to get the information you can and try to make the pieces fit.
The fuel pools are still there as is most of the highly damaged reactors. When any of them fall down all the people of Japan will be running to the exits as quickly as possible-we will definitely know when that happens.
