Uranium reserves are unevenly distributed across the planet and even more unevenly distributed across the planet are uranium enrichment capacities. Germany's refusal to develop nuclear energy looks less populist and frivolous when viewed from the aspect of dependence on enriched uranium imports. To reduce dependence on Russian gas in order to become dependent on Russian uranium is a dubious deal in the long run. Even the United States cannot now refuse Russian enriched uranium, so you will not find uranium and the state corporation Rosatom on the sanctions lists.
Interesting argument you raise, I had not heard it until now.
So what do you think could be the solution for Europe to have enough energy supply?
Hydrogen. More precisely, a mixture of 80% hydrogen and 20% natural gas (because hydrogen itself is a very volatile gas). For this mixture, the existing infrastructure of gas pipelines and underground storage facilities can be operated without changes.
