Hi@all, very informative 1:22:09 video on Liquid-Floride Thorium Reactors. www.youtube.com

Someone commented that I should look nto the THTR-300 fuel pebble event.

Germany shut down its thorium project due to high costs and a radioactive release (the THTR-300 event) : "On September 1, 1989 the THTR-300 was deactivated due to its ever rising cost: in August, 1989, the THTR-company became almost bankrupt after a long shut down time due to broken components in the hot gas duct. It had to be bailed out by the government with an amount of 92 million Deutschmark[3]. Also, increased public scrutiny following both the Chernobyl accident and the THTR-300 fuel pebble event of May 4, 1986, in which a fuel pebble became lodged in a fuel feed pipe to the core and some radioactive dust was released to the environment, played some role in the decision for shut down. Further German utilities had lost any interest in pebble bed reactors." en.wikipedia.org

Is anyone aware of a map of Cesium137 soil contamination since the March 29 map show here onioni2.blogspot.com ? I've found one for Cesium134 + 137, but I'm looking for only Cs137.

@elainekirk, thanks! Was there a specific document there?

Product Description
This new book offers detailed analyses of the Fukushima No. 1 nuclear power plant accident that occurred hours after the March 11 Great East Japan Earthquake and tsunami.
"The Fukushima Nuclear Power Plant Disaster: What Happened in March 2011," in three parts, is an attempt to look into what went wrong at the Fukushima nuclear power plant in the accident, now rated a Level 7 major accident, the highest level on the International Nuclear and Radiological Event Scale (INES).
The first section of the book, written by Mariko Takahashi, a senior staff writer of The Asahi Shimbun, follows key developments at the Fukushima plant in chronological order. It examines how the government and Tokyo Electric Power Co. coped with the crisis, including the way they handled the release of information to the press.
The author also looks at how public concern about safety standards on the radioactive contamination of food grew as the nuclear accident unfolded. She observes: "People were not just troubled by the vague worry about contamination exceeding safety limits; they were increasingly distrustful of Japanese safety standards in general."
The second section, written by Toshihiko Katsuda, an Asahi Shimbun science correspondent based in Washington, looks at how the foreign media reported on the Fukushima nuclear crisis. In a nutshell, the author says many articles accused Japan of responding too slowly to the nuclear crisis.
"The point cited included the delay of venting from the primary containment vessel and of injecting the seawater to cool down the reactor vessel," he says.
The last section contains the results of an Asahi Shimbun public survey on the nuclear crisis.
The poll, among other things, shows that while significant segments of the public in China and the United States continue to give robust support to nuclear power, opinion in Japan, South Korea and France appears to have been rocked by the crisis. www.amazon.com $1 I think I'm going to get one.
