As a nuclear core designer and someone who earned a Ph.D. from the Massachusetts Institute of Technology in nuclear engineering, I volunteered to look into the situation at Fukushima No. 1 in June of 2011. Mr. Goushi Hosono, minister of nuclear power and environment, personally gave me access to the information and personnel who were directly involved in the containment operations of the postdisaster nuclear plants. After three months of investigation, I analyzed and wrote a long report detailing minute by minute how the nuclear reactors were actually disabled -Japan Times
At 11:20 in
Kenichi Ohmae, Nuclear Engineer: This is sheet two. This chart shows equipment loss of all the nuclear reactors such as power supply of AC/DC.
Therefore, there may be many people with the impression that Fukushima Dai-ichi reactor 1 to 4 are in the most severe difficulties, but actually, other reactors are all in considerably severe condition with the external power, or emergency power devices.
The red marked devices are broken.
Regardless of such extreme situations, though not much has been broadcast, as you will find in the sheet, in all reactors except for one, two, three, and four of Fukushima Dai-ichi, cold shutdown occurred well until the end.
