More on 77-year-old 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.
A Todai as-hole though he may be, I started to like this guy as I watched. He didn’t mince his words, and said what they are doing at Fukushima I Nuke Plant is not working. That surprised some, including the host of the show, as Ishikawa is known as a strong proponent for the nuclear power generation and the nuclear industry.
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.
Here’s what I’d add to the snippets on my previous post. (My summary translation of what Mr. Ishikawa said, not literal; my comment in square bracket):
About TEPCO’s “roadmap:
“I believe what they are trying to achieve after 9 months is to cool the reactor cores and solidify them so that no radioactive materials can escape. But they are just doing peripheral tricks like water entombment and nitrogen gas injection. Nitrogen gas, it’s dangerous, by the way.
“What they must do is to cool the reactor cores, and there’s no way around it. It has to be done somehow.”
About the condition of the reactor cores:
“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.”
[He’s an old-timer so he’s used to curie instead of becquerel as a unit. 1 curie equals 3.7 x 10^10 becquerels (37,000,000,000 becquerels or 37 gigabecquerels).
10 million curies equals 370,000 terabecquerels, and 1 million curies equals 37,000 terabecquerels. I used this conversion table. Tell me I’m wrong! Cobalt-60 alone would make a Level 7 disaster…]
Plutonium has been found in the US:
Americium is even more heavy than uranium!

– Are There Safe Levels of Radiation? How Much Radiation Is Safe? (Must-read!!!!!)
A radioactive cloud from the quake-damaged Fukushima reactor explosions in Japan was said to have reached Vietnam in late April 9.
According to the Ministry of Science and Technology (MoST), the cloud may exist in Southeast Asia within several days with radionuclide concentrations decreasing with every passing day.
The most powerful radioactive cloud, however, dispersed rapidly on April 9 and 10.
Earlier, MoST said even if the cloud covered Vietnam, the radiation level would increase by only 100 times from the previously-detected level.
By 15:00, April 9, apart from the recognition of the natural radioactive isotopes, the observation stations in Da Lat and Ninh Thuan also discovered radioactive I-131.
In Ho Chi Minh City, the radioactive isotopes I-131, Cs-134 and Cs-137 were recorded.
“The radioactive isotopes recorded at the three above-mentioned locations are at low level, and do not pose a threat to human health and the environment,” scientists said.
Cs-134 was found in the pine needle samples (which are often used to indicate radioactive pollution in the atmosphere and vegetation) in addition to the isotopes Be-7, K -40, U-238, Th-232 and Cs-137 but the level of Cs-134 was very low and does not affect human health.
