That's a common claim but it's not really correct.
Firstly, the average plant in the US spends it's construction costs every 2-3 years, I assume the situation is similar in the EU. New power plants are much more expensive of course, because the old ones were built before Chernobyl, Fukushima, 9/11 and other incidents that revealed horrible security flaws in existing plants and procedures.
Secondly, the costs of handling Chernobyl are way, way higher than the total cost of construction for all nuclear plants in the EU combined. Similarly the cost of managing Fukushima is way higher than the cost of constructing all the nuclear plants in Japan. These costs are of course never added to the cost of nuclear power, since nobody operating nuclear plants has any chance of paying such sums. But they are in fact a larger factor than the construction costs were.
These experiences did have some effect, thankfully, in that made new power plants more expensive, because we know that we must take any conceivable measure to prevent more Chernobyls and Fukushimas from happening.
And thirdly, the reason why Sweden closed the two most recent reactors was cost, despite them being paid off a long time ago. Meaning there is significant cost even after the construction is paid.
So it seems that the claim that "construction is the main cost" comes from the operator's point of view. Basically "the construction is the largest part WE have to pay, because taxpayers cover the rest".
It's a common claim because it's correct.
> the average plant in the US spends it's construction costs every 2-3 years
That includes paying principal and interest on the construction loans, right?
> New power plants are much more expensive of course, because the old ones were built before Chernobyl, Fukushima, 9/11 and other incidents that revealed horrible security flaws in existing plants and procedures.
The modern cost increases have nothing to do with actual deficiencies in older US plants. Chernobyl had no containment building and a positive void coefficient. Even the US nuclear power plants build in the 1960s have a containment building and a negative void coefficient.
> Secondly, the costs of handling Chernobyl are way, way higher than the total cost of construction for all nuclear plants in the EU combined.
It's a good thing none of the US nuclear plants have ever been Soviet RBMKs then.
> And thirdly, the reason why Sweden closed the two most recent reactors was cost
The reason was that their electricity prices were very low at the time from a combination of having a large amount of hydro and the then-price of natural gas being low. Most places have no ability to control either of those things. Meanwhile how is the decision to close those reactors looking given how prices are now?
One would think! But no, all US plants except Vogtle and Watts are paid off long ago.
Now, why did you just throw that out there without checking? Are you not interested in knowing the truth, you just want to argue for nuclear no matter what the facts say?
If so, let me assure you that neither one of us will enjoy a continued discourse on the topic.
Just have to say though - that the Swedish reactors were closed because electricity was cheap is the point. Sweden basically stated that even when paid off, nuclear can't survive if electricity is cheap. But surely we, the taxpayers and businesses and industries, want it to be cheap?
I'm genuinely interested, can you share the numbers you're referencing? It's surprising to me that a massive project like a nuclear reactor costs 1/3 of the inflation-adjusted total construction cost per year in upkeep. I'm not saying you're wrong, just the easy way to prove your point would be to provide some numbers.
Because it can't possibly be (and isn't) an accurate claim for the recent plants with modern construction costs. Whereas if you're comparing the 1970s construction costs to the modern day operating costs to imply that the operating costs are high, that's obviously not a useful comparison to begin with.
> But surely we, the taxpayers and businesses and industries, want it to be cheap?
We might want it to be free, but we also want some other things, like "doesn't burn carbon" and "can reliably heat your house on a cloudy winter night". And then the question is, what's the most economical way to get those things?
If we learn that even if we make new nuclear as cheap as old nuclear, it's is still not cheap enough, surely it is a very useful comparison?
It's not useful if the goal is to defend nuclear at all costs, I'll give you that, but that's not a worthy goal.
>And then the question is, what's the most economical way to get those things?
Absolutely, and that's why finding out the real, actual truth of the costs is very important.
If you add the true cost to society from things like Sellafield, Asse II, the interest-free loans, the army personnel and national labs handling waste, the decades of countermeasures for Chernobyl in dozens of countries and so on - if you add upp all that, perhaps generating e-fuel is actually cheaper than nuclear?
If not already, the Chinese have taught us that once you get the wheels rolling, prices decimate pretty rapidly. They made solar and batteries viable, maybe we could do e-fuels?
Synthetic fuel, batteries everywhere, pumped storage, geothermal, gravity, pressurized air, heated salt - maybe all of those are actually cheaper than nuclear, if we really add up ALL the costs of nuclear?
At a certain point it just becomes cheaper to build a brand-new one right next to it and decommission the old one, even with a nuclear reactor.
There are nuclear plants built in the 60s and 70s that are not only still operating but in the process of extending their operating licenses in order to keep operating for decades more. The period of time it takes before this makes "keep operating it" unviable is evidently pushing 80 years without actually hitting the limit.
Control rooms and reactor vessels are themselves made of modular components and a lot of maintenance to those things happens during refueling.
> On top of that it locks you in to an old reactor design, which might be very undesirable for safety reasons.
That can't be the argument against building new ones. It's the argument that what you want is to build the newer, safer designs and then operate those for a long time.
