First of all, we deeply apologize to all residents of Fukushima Prefecture as well as broader society for the concern and anxiety that has arisen on account of the accident at Fukushima Daiichi Nuclear Power Station (NPS) due to the March 11, 2011 Tohoku - Pacific Ocean Earthquake.
The accident at Fukushima Daiichi NPS was caused by the loss of reactor core cooling functions and the prolonged simultaneous loss of all Alternate Current (AC) and Direct Current (DC) power due to the 13 meter-height tsunami brought about by the massive M9.0 earthquake.
What followed after was the extremely serious accident in which a series of explosions occurred at the reactor buildings and radioactive materials were released into the atmosphere and ocean. Since then, we have been making a concerted effort to achieve a full recovery while receiving support from the government, relevant domestic and overseas organizations and manufacturers.
As of December 2011, we have achieved conditions equivalent to a cold shutdown. This is the state where the inside reactor temperatures of Units 1 through 3 have decreased to approximately below 100 degrees C and the release of radioactive materials has been significantly suppressed and is being kept under control. Currently, efforts to steadily cool down the reactors, control radioactive emissions into the atmosphere, and stop all radiation leakage into the ocean remain ongoing.
Hereafter, per the Mid-and-Long-term Plan prepared in conjunction with the government that was released in late December 2011, we will move forward with such activities including our primary mission to decommission Units 1 through 4. In order to enable the evacuees to return home as soon as possible and restore peace of mind to all the citizens of Japan, we will do our best to maintain the cool state of the reactors and prevent further radioactive emissions.
In the following content, we will take a look back upon the tumultuous year that transpired at Fukushima Daiichi NPS and go over the many challenges we faced and how we dealt with them.

We all know the reason...and it ain't solar winds. It's the same reason you don't get high numbers....yet.
Then Prime Minister Naoto Kan verbally lashed Tokyo Electric Power Co. officials shortly after the hydrogen explosions at the Fukushima Daiichi nuclear power plant last March, ordering them to contain the crisis at all costs, company records showed Thursday.
"It doesn't matter if the company executives aged around 60 die at the accident site. I'm going, too," Kan is quoted as saying, during his visit to TEPCO's headquarters in the early hours of March 15.
Kan also said, "The state of Japan could go to ruin if the situation stays as it is...If TEPCO abandons the Fukushima plant, reactors and spent nuclear fuels could collapse and radioactive substances could be released," according to the records.
* This value was described from today because full operation of the PCV gas control system started.
Two citizens' groups in Fukushima Prefecture plan to file a criminal complaint against senior officials in the government and Tokyo Electric Power Co. for professional negligence over the nuclear crisis.
Members said the antinuclear groups will hold a rally Friday in Iwaki, Fukushima Prefecture, hoping to recruit at least 1,000 residents of the prefecture to lodge the complaint in mid-May with the Fukushima District Public Prosecutor's Office. Group members say they intend to target officials of the Nuclear Safety Commission of Japan and the Nuclear and Industrial Safety Agency as well as Tepco.
They will claim that the failure of Tepco and the government bodies to prevent the catastrophe left many people exposed to radiation, and that some inpatients died while fleeing from nearby medical institutions. The groups are also considering accusing the officials of violating pollution laws by spreading massive amounts of radioactive substances.

After posing my ideas on the Japanese nuclear disaster to a lead scientist at GE-Hitachi, and receiving a favorable approval I then sent messages to the Japanese government.
The gist of it was to use helicopters, fast ships (possibly destroyers ); airlift (using skycranes ) the debris, metal, buildings, anything 'contaminated' , load it onto ships, using lead shielding where possible....
Head to the Hawaiian Islands and/or nearest active volcano and dump it in. Let nature put it back to as close to elemental form as possible, and lock up the molten residue in rock.
Other than nuclear countries taking their waste rods and such, loading them on rockets and shooting them to the sun, moon, .... we must live with hard choices on 'what' to do with the 'hot' materials.
No, this is not a perfect solution but it would work. The Japanese thanked me for the suggestions. That was it.
