Version von Wave of anti-nuclear protest after reactor accidents in Japan vom So, 20.03.2011 - 23:39
A gigantic earthquake and subsequent tsunami struck Japan on 11 March.
Thousands of people were buried under buildings or died in the flooding. In
many of Japan's more than 50 nuclear reactors cooling systems broke down.
This caused several hydrogen explosions and at least partial fuel rod
meltdowns in the reactor blocks one to four of the Fukushima Daiichi nuke.

The 11 March earthquake, subsequent quakes and flooding waves severely
damaged several atomic installations in Japan. Inter alia an explosion on
Saturday destroyed the building of reactor block I of the nuclear power
station "Fukushima daiichi genshiryoku hatsudensho" where fuel rods are
melting down. On Monday there was a second hydrogen explosion in reactor
block III which uses plutonium as well as uranium. It also emerged on Monday
that the fuel rods in block II are completely dry and exposed. The necessary
cooling is not working in at least four more of the more than 50 reactors in
Update 15.03. 14:30: In the cooling basin of Block IV fire broke out, radioactivity got into the atmosphere. High radiation levels are measured, personnel were evacuated from the control room. Cooling in Blocks V and VI is not working properly.
Update 16.03 9:45: After another fire in block IV, ongoing damage in block III and rising radiation the remaining 50 workers were temporarily withdrawn from Fukushima. The military tries to cool the reactor with helicopters.
Update 16.03 15:00: The helicopters could not cool the damaged reactorblocks because of high radiation. Now police water-canons will try to cool them.
Update 17.03 9:00: During the last hours helicopters
and police water-canons tried again to cool the reactor. Tepco is
working on reestablishing the electricity-supply. US-army drones try to
photograph the reactor.
The evacuation radius around the first accident reactor was extended to 20
kilometres on Sunday. Media and government are trying to downplay the
seriousness of the situation. Reliable information about no longer deniable
happenings is being gathered by the IAEA. Independent nuclear experts no
longer doubt that the situation is close to the worst expectable, that is,
almost totally out of control. Attempts are being made to fill reactor
blocks I - IV with sea water to prevent further overheating. Experts say
this emergency measure is "not provided for in this form in any manual" and
renders the reactors permanently unusable. The contaminated water turns into
steam or runs back untreated into the sea.
Nukes have also been built in potential earthquake areas elsewhere, for
example the scrap reactor in Fessenheim, France. It is also important to
note that it was not the earthquake and tsunamis as such that put the
Japanese reactors out of control, but in the final analysis it was the
failure of the power supply. Even in areas not vulnerable to earthquakes,
power failure is a crucial nuclear vulnerability.
For election-tactical reasons the CDU-FDP (conservative-liberal) coalition government wants to suspend for three months the extension of nuke running times and offers as a sacrifice the final closure of Neckarwestheim I, and closure for three months of six other nukes built before 1980 as well as Krümmel, which has been out of action for years because of endless mishaps, intending to keep using what it calls the "bridging technology". Switzerland is putting a moratorium on construction of new nuclear power plants.
