This is one of the main problems with atomic energy that we haven’t got any idea how to use
Doesn’t this apply to almost any form of power generation? Fossil fuels and raw materials for nuclear fuels are often imported from undemocratic or unstable countries. As are many of the raw materials required for renewable power generation and storage.
Using this as an argument againt nuclear power is as intellectually dishonest as the people using it as an argument against electric cars.
