I think this is vastly misunderstood in the (artificial) renewables vs nuclear conversation. We keep building effectively one-off complex machines, and then flushing all that knowledge down the drain by saying it cost too much and took too long. Like yes, the first one always takes longer and costs more...

The difference is that nuclear is the only one where the first one’s cost is measured in the the tens of billions. Nuclear is just too big for a privatized energy market’s participants.

It’s not too big, just too politicized. Bill Gates wanted to do it for a long time, but he can’t get the political buy in.

For me even seeing the Tesla Berlin factory delays makes me sad: in China already the second factory is being built while Germany is coming up with new arguments without looking at the cost/benefit ratio for EU of those delays.

What's surprising is the length of time of this project. It was started in 2000, and just completed. That's 23 years of development. These nuclear projects appear to take a significant amount of time. By comparison, this wind turbine project near my parents was approved in 2016 and completed in 2018, providing 78 megawatts of power. Yes that's significantly less than the 1.6 gigawatts of this Finnish power plant. But…

In a word, reliability. Nuclear is /by far/ the most reliable energy source.

Nuclear power plants produce maximum power 92.5% of the time. Compare that to other energy sources:

- Geothermal: 74.3%

- Nat gas: 56.6%

- Hydropower: 41.5%

- Coal: 40.2%

- Wind: 35.4%

- Solar: 24.9%

Batteries are a joke. Consider the 409MW / 900MWh battery at Florida Power & Light: this is only enough to power 329,000 homes just over two hours. What happens after the juice runs out? In a day the RE Ginna Nuclear Plant in New York operates at 582 MW--in 24 hours thats 13,968MWh guaranteed! [3] That's powering over 329,000 or more homes without fear of outages. Battery systems in conjunction with renewables brings the capital cost per kwh of nuclear vs renewable to closer to 2:1 (6k $/kW vs 3k $/kW) too. So you're essentially getting 3x the reliability for 2x the cost when using nuclear and outages that exceed a few hours are a non issue. [4]

Without including storage and overbuilding of solar and wind to provide the same capacity factor as nuclear it is not a fair comparison, so it doesn’t point out how uneconomical this nuclear project is. The attractiveness of 1.6 GW of nuclear power is that it is carbon free, statistically the safest, it is firm energy that can be depended upon 24x7x365, and fuel costs are so trivial nobody even brings them up. All of…

> so it doesn’t point out how uneconomical this nuclear project is.

It does insofar as it matters for capital. Who wants to invest in a plant that will take at least ten years (but probably more with cost overruns in the billions) before they see a ROI? Especially when the cost per MWH from a renewable project that will be online in 2 years with less risk is already comparable if not more competitive.

The other sources produce less because they can. Since nuclear has a high capital cost and low variable cost it bids low.

We (Finland) are probably not going to move towards electric heating to any significant degree. Currently direct (resistive) electric is already the most common means of heating in single-family homes and other low-density residential buildings. Heat pumps are fortunately becoming popular especially in new development, and with them a significant reduction of electricity use compared to direct electric. For condos an…

Geothermal boreholes are suddenly much more practical than anybody had guessed, with laser drilling. Its operating cost will necessarily be quite a bit more than solar, but it works in the Arctic winter, 24x7, and provides cogen heat.

Knowing that we have test plant with geothermal and the depth required is 6,4km even with laser drilling the effectiveness might not be so great.

Isn't it the other way round?

It’s a question of temperature difference. Cooling a house from 40° to 20° uses approximately the same energy as heating it from 0° to 20°. But it gets much colder than 0° C in Finland, while it is very rare to have temperatures above 45° C anywhere in the world.

How much does construction affect the efficiency?

I've read that the startup process of building new or subsequent nuclear plants will be considerably shorter due to the groundwork for the Finnish reactor paving the way.

Which seems to topple most of your argument.

As for wind turbines on land, they require a lot more space for the same yield, space which is stolen or irreversibly destroyed for the local fauna. Here in Norway, wind turbines near settlements are also forced to run on diminished capacity at night because of the health problems people associate with the 24/7 humming and whoosh noises (not kidding).

It is more than 14%. It looks like this plant, all three reactors together, might eventually cover a third of Finland's needs. But those are 2020 numbers. Increased electrification, especially EVs and moves away from gas, will probably reduce that percentage. In that context, the third reactor is only incrementally more powerful than those already running at the facility. "The Olkiluoto plant consists of two boiling…

If those EVs are mainly charging at night, where does the extra peak load come from? Or is this just a case of not being able to shut off as much NG/Hydro generation at night (since nuclear can’t really be turned on and off at will)?

Why do EVs mostly be charged at night?

We have electricity run to almost everywhere there is a road, and every building that we spend any significant amount of time in. We can charge at work or on the street during the day. Basically anywhere a car is stationary.

With the right incentives and infrastructure we can shift electric vehicle charging to daytime, or whenever there is excess generating ability coming from the grid.

While 23 years to build the thing are already bad, it now needs to operate continuously for at least some 30 years selling electricity at a price that is even today not competitive with renewables to make financial sense. Essentially, building a nuclear power plant in 2022 means you are betting we won't have workable storage for renewables by 2052.

Today, what are the alternatives?

If you add in batteries with todays technology the nuclear plants are competituve with solar or wind.

So the alternative is coal or natural gas plants. Which then have their own drawbacks.

Solutions that are built today need to use technology available today.

Nuclear is fine, especially when you are not buying the first reactor of its kind from a vendor who has never fully built a plant on its own. Areva got a tad too greedy and cut out the middleman in the form of doing 100% of the work themselves instead of the usual 30% and contracting out the rest. They ware not helped by the fameously strict Finnish regulatory authority (STUK).
