Beznau 1: The first Swiss nuclear power plant in 1969 the work I Beznau to the mains, two years later was right next to a second identical reactor was inaugurated. Beznau I and II are pressurized water reactors with a capacity of 365 MW, which are cooled by river water and therefore no cooling tower benötigen.Das power plant is located in the canton of Aargau on an island in the River Aare, just a few miles above the confluence with the Rhine at Koblenz and it also just a few miles from the German border.

The security clearance of the Swiss Federal Nuclear Safety Inspectorate unearthed in April the following vulnerabilities: "The earthquake behavior of the fuel storage building is in need of improvement. The fuel cooling is not sufficiently protected against earthquakes and flooding. The emergency measures to restore the cooling after earthquakes or flooding are incomplete. "Retrofitting that would fix these security flaws would, according to newspaper reports, cost tens of millions.

As the left-wing weekly newspaper WOZ recently reported in 2007 were not in Beznau emergency generators ready - an incident that demonstrated forcefully that in the event of an earthquake, not a catastrophe could have been stopped. " The system must therefore - but only until 2014 - will be retrofitted with additional generators.

2 Leibstadt: only five kilometers in a straight line from the Rhine Beznau away is the latest Swiss nuclear power plant Leibstadt. It also lies in the canton of Aargau, right across from Waldshut. The work went so far as the last Swiss nuclear power plant in 1984. It is a boiling water reactor with a capacity of 1165 MW, so is the body of the city's most powerful Swiss nuclear power plant and supplies, according to the operator about 15 percent of the electricity consumed in Switzerland. Each year, about 23 tons of uranium are consumed. As fuel in Leibstadt only enriched uranium is used.

Security screening in April 2011 led to only that the level and temperature of the fuel storage tank in the emergency control room will not be displayed.

The nuclear body city has a 144 meter high cooling tower. The special feature: "For over ten years, the cooling tower, the home of a peregrine couple, one in Switzerland is very rare and beautiful bird of prey as" how to write the plant operators. Video cameras transmit the images from the front room of the peregrine family into the information center of the nuclear power plant. What a trip right now could pay off - for the breeding of peregrine falcons can be seen until late May. Then have to move the three young peregrine falcons and find a new home.

3 Gösgen: Tens of thousands of rail passengers see every day the Gösgen whiz in front of the train window: it is only a kilometer away from the busiest rail line in the country, Bern-Zurich, near the small town of Olten in the canton of Solothurn. And this work is less than 20 miles as the crow flies from the German border. Gösgen went on line in 1979, it is a pressurized water reactor with 970 megawatt capacity.

Similar Leibstadt the security check revealed in April for Gösgen only a lack of ads in the control room.

At a recent information meeting said manager Mark Rüegger that the safety devices are superior to those of Fukushima Gösgen in several ways: "The NPP Gösgen has four emergency diesel generators, plus two emergency diesel emergency power. Instead of us in six Fukushima had only two diesel per block, "said the Aargau Rüegger newspaper.

"Gösgen" also stands as a symbol of the widening public protests against nuclear power. were planned in the 60's, when the first Swiss nuclear power plants and constructed, there was little opposition, this changed in the 70's: Prior to and during the construction period, there were always counter-rallies. Because of the increasing resistance finally, the project of another nuclear power plants in Kaiseraugst near Basel was buried.

Muhlenberg 4: The boiling water reactor from Muhlenberg with 373 MW capacity is also located along the river and is considered the real cause for concern among Swiss nuclear plants. Because it removes less than 15 kilometers from the capital Bern, and in addition to the prevailing wind direction West: A nuclear accident would therefore immediately threaten a large, densely populated area. And safety study in April showed that for the longest Muhlenberg "snag list": The nuclear plant is located below a large dam, an earthquake would damage the dam of the hydroelectric plant, then the nuclear power plant would also be at risk.

Because it draws its cooling water from the river and there is no alternative. Especially the insufficient cooling water supply was indeed a major problem in Fukushima.

Moreover, according to the safety report that even in protected Muhlenberg "the fuel pool cooling is not enough for earthquake and flood (is). The emergency measures to restore the cooling after earthquakes or flooding are incomplete "Finally, several years ago hairline cracks found in the core shell;. The plant operator has converted the plant to tie rods, which is the competent nuclear safety authorities, but not recognized in the long run. Muhlenberg only use uranium as fuel and not a mixed oxide.
