Swiss without nuclear power after shutdown
Source: The Local
Switzerland on Monday was temporarily without nuclear power because all of its reactors were out of service for repairs or maintenance.
Utility company KGD announced on Sunday night that it was disconnecting the Gösgen nuclear plant in the canton of Solothurn from the grid to resolve a steam leak problem.
The utility said that to perform the needed repairs it had to turn off the plant to cool the the impacted area.

Gösgen is one of four nuclear power plants in Switzerland with the others already down for repairs and servicing, the SDA news agency reported.

Nuclear power is unreliable as well as expensive, dirty, and dangerous.

Yes, 42 hours of sunshine in December (on average). That's about an hour and 20 minutes a day.
Yeah, solar is totally the best option there...

Solar is definitely part of the energy puzzle in Switzerland

Since Friday block 2 at the nuclear power plant Beznau in canton Aargau has also been offline. Itll be out of service for four months while maintenance is carried out. Among the planned tasks is the replacement of the reactor pressure vessel cover. Block 1 at the plant has been out of service since March due to irregularities in the pressure vessel. Weak spots were found in the 15cm steel covering of the vessel.
ENSI is currently expecting a progress report from the plants owner, Axpo, and service will only be allowed to resume when safety and security at the plant can be guaranteed. Beznau is the oldest active commercial nuclear power plant in the world. It went online officially in September 1969.
Nuclear power plants in Leibstadt and Mühleberg are also currently not producing any energy due to annual maintenance service.
In 2011 Parliament agreed to bring an end to nuclear energy production in Switzerland, but political discussions about exactly when this will occur are still ongoing.

(5,938 posts)of one average nuke (1000MW lets say). Ponder that. Just 200 wind turbines similar to the ones they're installing off Block Island at this very moment. Compare the utter simplicity of Just 200 windmills with the unbelievable complexity, expense and danger of a nuke.

(5,938 posts)Goes straight into the grid. Consider Block Island or Vinalhaven Maine - the cable connecting the windmills is bidirectional- when they need juice, they draw from the grid, when the wind turbines provide more juice than they need- they sell the excess to the grid via the same cable.
bobclark86
(1,415 posts)That's how much juice the nuke plants pump out a year in Switzerland. The project you're talking about is about 5 percent of that, according to its Wikipedia page.
To get that, at the rate US turbines generate, is about 9 GW worth of turbines. So more like 1,500 turbines.
And that's assuming Switzerland -- which has no shore to put them off of -- can use the big 6MW off-shore turbines. So more likely the 2-2.5 MW turbines used on-shore in the U.S.
So it's now 3,600-4,500 turbines.
Does Switzerland have enough good, windy hilltops -- near modern sections of the power grid that can handle the extra power -- for 4,500 turbines?
Blues Heron
(5,938 posts)Switzerland has zillions of hilltops, thousands and thousands of which are windy. They also have expertise in high mountain construction and power line installation. 4500 turbines is nothing.

(5,938 posts)4500 turbines is nothing. Easy peasy, piece-of-cake level of civil construction. We'll be building far more than 4500 of these in the coming years.

(26,748 posts)Total offshore wind capacity installed to date is about 10 GW.
You're talking about producing well over twice that amount per year as though it's easy.
Save some of what you're smoking for the rest of the group.
FBaggins
(26,748 posts)Closer to 3-4 times that many.
Just 200 wind turbines similar to the ones they're installing off Block Island at this very moment
That would be the one that's expected to cost $300 Million for five turbines?
Even if we assumes that it would only take 200 of them (essentially assuming that wind will blow 90% of the time), that would be $12 Billion to replace that one nuclear unit... and then they have to do it again 20 years later... and then again 20 years after that.
It's also ridiculous to talk about the "utter simplicity" of offshore wind generation. It's actually a pretty challenging environment

(19,253 posts)30%, to offset the 30% that nuclear supplied. In the past, they actually exported electricity due to massive hydroelectric dam projects.
The question is, who are they importing electricity from? France generates electricity primarily with nuclear; while Germany to the north uses a mix of wind, solar and coal.
