Construction of the Advanced Liquid Processing System at TEPCO’s ruined Fukushima nuclear power complex (photo: TEPCO, via mainichi.jp). Still dealing with the aftermath of the 2011 Tōhoku earthquake, subsequent tsunami, and three meltdowns at its Fukushima I nuclear power complex, Tokyo Electric Power Company had more bad news yesterday about its Fukushima ALPS cleanup efforts.
Bad news from the annual American Geophysical Union’s Ocean Sciences Meeting in Honolulu. Researchers there announced today that radioactive isotopes from the Fukushima nuclear disaster, when three reactors melted down after the March 11, 2011, Tohoku earthquake and subsequent mega-tsunami, have finally reached the West Coast. John Smith, a research scientist at Canada’s Bedford Institute
TEPCO workers lower the 91-ton shielded transfer cask in preparation for relocating unused nuclear fuel. (Photo from TEPCO.) Today, officials at Tokyo Electric Power Company could breathe a sigh of relief. Using remote-controlled cranes, workers at Fukushima Daiichi cleared some of the dangerously radioactive uranium fuel rod racks from the upper-story cooling pond of damaged
NHK World reports the beginning of Fukushima Reactor Unit 4 fuel rod transfer. (Screenshot of NHK broadcast, video released by TEPCO.) The ticklish operations involved in decommissioning Tokyo Electric’s ruined nuclear power plant at Fukushima began on Monday. Workers at the plant began removing unused nuclear fuel from the fourth-floor storage pool at the damaged
With a photo of fuel rod assemblies in the background, nuclear engineer, former executive, and educator Arnie Gundersen explains his doubts yesterday about the nuclear fuel relocation at Fukushima Unit 4 (screenshot). Brace yourselves. Japanese media and the UPI reported early today that TEPCO has scheduled the ticklish job of relocating highly radioactive nuclear fuel
Readying Fukushima 1 Unit 4 for decommission operation, but… (Kyodo News/flickr.com/photos/simplyinfo/) Not so fast with the Fukushima decommissioning, TEPCO. A Japanese government-affiliated agency (the Japan Nuclear Energy Safety Organization) has advised the Tokyo Electric Power Company that its proposed method of clearing Reactor Unit 4’s exposed cooling pool needs a test run before anyone commits
Here’s what the Fukushima I power nuclear plant complex looked like prior to the natural disasters and explosions. (Source: ad-hoc-news.de.) Before March 2011, if you heard the words “Fukushima Daiichi,” you might wonder if someone had concocted a new sushi roll. Now most of us know about the nuclear accident cascade following Japan’s massive Tōhoku
Preparing to decommission the Fukushima Daiichi nuclear plant, TEPCO recently dismantled the damaged roof parapet of Unit 4 and removed debris there. (Screenshot source: Enformable.com/Lucas W. Hixson.) As early as next Friday (November 8), the scariest decommissioning work at the ruined nuclear power complex may begin. Tokyo Electric Power (TEPCO), the largest electrical utility in

Some top green news from around from the past day or so: Global Warming Heartland associate taught ‘biased’ climate course at Ottawa university An associate of the Heartland Institute, the thinktank devoted to discrediting climate change, taught a course at a top Canadian university that contained more than 140 false, biased and misleading claims about
As if the people of japan haven’t suffered enough devastation, reports say Typhoon Ma-on is heading toward Fukushima. While workers at Tokyo Electric Power Co( TEPCO) is rushing to install a cover over a building at its crippled Fukushima Dai-ichi nuclear plant to shield it from wind and rain as Typhoon Ma-on approaches Japan.
The Topic: Radiation Exposure.
The Question: How do scientists know what kind of (and how much) radiation exposure we do or do not face?
