Yes you are right.


We will never forget all of this and as important as it all has been, I think that six months is a good point to unpin this. The thread is and always will be here and if people post in it, which anyone of course is welcome to, it will be near the top just like other topics.

More please!   http://www.youtube.com/watch?v=0HrO2H4Sraw   You'd think they might put in some of the overly loud throat noises and he would do a big "ahhhhhhhhhh" at the end. Come on, where's th

What a horrible gaffe for a politician to make - saying that a place where nobody can go because they would die looks, well, dead. There were all these ex-residents, brimming with hope for the future, and that bastard had to go and crush their dreams!


He should have been bright and jovial and made light of the risks such as the radiation on his clothes.


Oh, wait a minute, he did.


The problem with these pols is that they lack the courage to say "Come here and say that" when hounded by that miserable pouty son of the Governor of Tokyo who hasn't let a single policy statement escape his lips in ten years.

Electric supply companies looking to limit things in winter as per this summer?

Was horrified to see it all happen in March.

And then very touched by how the Japanese dealt with it.

Respect, for sure.

Hope that things are getting sorted with some sort of speed.


I will be visiting this winter! :party:

The temperature at the base of the No. 2 reactor at the Fukushima No. 1 nuclear power plant fell below 100 C for the first time since the March disaster, according to Tokyo Electric Power Co.

TEPCO said the temperature was 99.4 C at 5 p.m. Wednesday. This means TEPCO has brought the temperatures at the base of the Nos. 1 to 3 reactors at the crippled plant to below 100 C, meeting one of the two conditions for the reactors to be in a stable cooling state, known as cold shutdown.

Compared with the Nos. 1 and 3 reactors, it took more time for TEPCO to cool the No. 2 reactor. On Sept. 14, the utility started increasing the amount of water injected into the reactor gradually from three to four tons per hour. The company also introduced a new method of spraying water from overhead like a shower. As a result, the amount of water injected into the No. 2 reactor reached 10 tons per hour by Monday.

Achieving cold shutdown is a major milestone in the Step 2 phase of the government's road map to contain the nuclear crisis triggered by the March 11 earthquake and tsunami. The government aims to complete Step 2 within the year. Achieving this will allow the government to move ahead with its study on whether it should allow evacuees to return home.

In addition to bringing the temperatures below 100 C, TEPCO needs to curb the leakage of radioactive substances from the plant significantly--another condition of cold shutdown.

Let's plutonium!




Plutonium believed to have been released from the crippled Fukushima No. 1 nuclear power plant after the March 11 earthquake has been detected outside the power plant site for the first time, it has been learned.

One of the spots found contaminated with the hazardous substance is 45 kilometers from the plant.

A map released by the Education, Culture, Sports, Science and Technology Ministry on Friday shows plutonium was found in soil samples taken from a total of six locations in Futabamachi, Namiemachi and Iitatemura, Fukushima Prefecture.

The map is based on a survey conducted by the ministry to determine how much soil around the power plant contains plutonium and strontium, which is also a hazardous radioactive substance.

However, a ministry official said because amounts of both substances were very small, decontamination efforts should focus on radioactive cesium.

The survey was conducted in June and July by sampling soil at 100 locations around the plant. The ministry compared the data obtained from the survey with data obtained in surveys conducted from fiscal 1999 to fiscal 2008 to measure the residual effects of radioactive fallout on Japan from nuclear atmospheric tests conducted during the Cold War.

The six spots where plutonium was detected are all in the no-entry zone, within a 20-kilometer radius of the plant, or in the expanded evacuation zone outside the no-entry zone, which may be exposed to more than 20 millisieverts of radioactive substances within a year from the accident.

Four becquerels per square meter of plutonium-238 was detected at one site in Namiemachi in the latest survey. This is about half of the maximum quantity of 8 becquerels detected in the 1999-2008 surveys.

A preliminary ministry calculation shows that the level of plutonium contamination in Namiemachi will remain at 0.027 millisieverts for about 50 years. The other five spots were contaminated with 0.55 to 2.3 becquerels of plutonium.

The farthest spot from the plant where plutonium was detected was in Iitatemura, about 45 kilometers from the plant.

Meanwhile, strontium-89 and strontium-90, both believed to have been released from the power plant, were detected at 45 spots.

The maximum quantity of strontium-90, whose half-life of about 29 years is much longer than the approximately 50-day half-life of strontium-89, was 5,700 becquerels per square meter detected in Futabamachi. This is six times that of the maximum quantity of 950 becquerels found before the Fukushima plant accident.
