Not when coal and gas fill the void. They can get fuel rods from France, Canada, China. Hell Germany could just refine their own, Niger is looking for trading partners.

Nuclear energy was the answer between like 1950 and 2010. But the fact that China isnt going all in on nuclear despite having optimal conditions; central planning allows them to predict maximum prices for materials and labor available 5-10 years in advance, the scale allows them to produce reactors more efficiently with better investment in tooling than any other country, and being the workshop of the world ensures higher demand than any other country. They are at <5% nuclear right now and expect <10% by 2035.
