In eu France is the biggest net exporter in the EU while Germany with huge renewable capacity net imported 20+TWh this year. Look how Germany's generation was yesterday to get a sneak peek
Again, look at yesterday generation. They were not able to satisfy local demand with renewables and bumped up coal+gas by a lot.
Also, if you look at the numbers - the price difference isn't that huge but trade difference is huge. This year export price is less than 1$ more than import. Problem is Germany net imported 25TWh so they are still in a big trade deficit and it continues to grow considering dunkelflaute is ahead
Maybe stop looking at instants and start looking at the larger picture: keeping our cumulative emissions as low as possible.
Starting a nuclear construction project which won't deliver any decarbonization for 15-20 years is accepting large cumulative emissions.
Larger image is yesterday's generation + https://www.bloomberg.com/news/articles/2024-05-29/germany-s... and https://www.reuters.com/business/energy/germany-looks-specia...
And nuclear construction can be much faster https://en.wikipedia.org/wiki/Barakah_nuclear_power_plant or you can look at projects from China
