Summary
France’s Flamanville 3 nuclear reactor, its most powerful at 1,600 MW, was connected to the grid on December 21 after 17 years of construction plagued by delays and budget overruns.
The European Pressurized Reactor (EPR), designed to boost nuclear energy post-Chernobyl, is 12 years behind schedule and cost €13.2 billion, quadruple initial estimates.
President Macron hailed the launch as a key step for low-carbon energy and energy security.
Nuclear power, which supplies 60% of France’s electricity, is central to Macron’s plan for a “nuclear renaissance.”
Total land used for all power to be supplied by solar would be a hilariously tiny percentage of land, so this just reads like a solar version of “its killing birds” to me.
Agrivoltaics also side steps this non issue, as interlacing solar panels into farm land increases yields for many crops while making efficent use of space that’s already spoiled any biodiversity. Can you do that with a nuclear reactor?
Nuclear could take over existing coal plants which would allow use of otherwise unusable land that’s been polluted by coal. It would require regulatory changes though, as the coal plant is already irradiated beyond allowed levels for nuclear.
Yeah in a perfect world based on some rough data you could supply the entire planet’s energy requirements with a solar plant about 300,000 square kilometers, or basically the size of Arizona, which translates to about 0.2% of the total landmass on earth. That being said, I’m curious what a solar plant the cost of this nuclear plant would look like, and where they’d put it. I think centralized vs distributed land rights and compensation is really tougher than the tech at this point.
Nevada just built a hybrid 1400MW solar/battery plant for 2 billion dollars in 2 years.
That 1400MW is solar panel + battery output, so it doesnt match nuclear’s steady state, but ive done the math on these projects before. We should be able to can build a 3000MW solar generating plant with 1200MW battery supply for 16hrs at roughly a cost of 17 Billion dollars, or 1 Vogtle nuclear plant. My time estimate was 6 years. This would output 2x the power of the Vogtle plant during the day, and output just as much as it over the night.
The above makes solar/battery not only way more productive than nuclear, but way safer, and way faster to built. All of that is just with demonstrated, everyday tech available today. It ignores all the huge advances being made in various batteries and panels. In the decade+ that it would take to open just one more reactor, we will likely be able to 2x-3x the power and speed to build at a lower cost with just solar/battery.
Nuclear was the right answer for the last 50 years. That’s no longer the case.
