Sometimes I wonder whether Putin is a top secret Greenpeace agent meant to cut short the fossil fuels based buisness modell of Russia, which could do a lot of harm if unchanged. :)

Putin is a NATO sleeper agent, his goal is to convince all of Europe to join NATO.   :-DD

BTW, you can sometimes hear this argument: "Olkiluoto 3 got so badly overbudget and overschedule because Finnish authorities were so demanding with safety or outright sabotaging the project". This is an obvious lie and the proof is easy to find; the Flamanville 3 NPP, which had the benefits of being in the homeland of Areva, and starting two years later after using Olkiluoto 3 as a proof-of-concept, is even more overbudget and still not finished:


--- Quote from: Wikipedia link=https://en.wikipedia.org/wiki/Flamanville_Nuclear_Power_Plant ---A third reactor at the site, an EPR unit, began construction in 2007 with its commercial introduction scheduled for 2012. As of 2020 the project is more than five times over budget and years behind schedule. Various safety problems have been raised, including weakness in the steel used in the reactor.[1] In July 2019, further delays were announced, pushing back the commercial introduction date to the end of 2022.[2][3] In January 2022, more delays were announced, with fuel loading continuing until mid-2023,[4][5] and again in December 2022, delaying fuel loading to early 2024

At estimated cost of 19.1 billion, it will leave Olkiluoto 3 in shadows and create some of the most expensive electricity known to human kind.

--- End quote ---

Note that my notation of "1X input power = 3X renewable harvesting" is equal to COP of 4. That would be typical realistic for central Europe mild weather.

I always want to be a little bit conservative when promising savings, but COP exceeding 4 is indeed possible if the conditions are just right and the devices used in the correct way.

Oh, I see, I read 2,3 first, which would be already at around minus 10 degree Celsius.

--- Quote from: madires on April 17, 2023, 10:36:58 am ---My opinion on shutting down all nuclear power plants: it's total nonsense! Shutting down an old plant for safety reasons is fine, but it should be replaced with a new and hopefully better one. With the shift to electric cars and heat pumps for heating we'll need about three times the electric power we're generating at the moment. I don't see how we could achieve this by just adding more PV and wind generators.

I don't either, I've said that multiple times and mostly get shrugs.

We'll sure have to shrug a whole lot to get all this electricity generated. :popcorn:

The plants would need a major revision and there are not even regulations and thus no plans or preparations for that.
The idea of a restart is more like a pre-election idea of someone who is not in charge nor running for the relevant position.  So this is just for publicity.

Well, restarting an existing plant is quicker than building a new one. The main problem I see is to get the people together with the right knowledge.
