vas-y, viens, on construit une bombe atomique

The video explores the complex process of building a nuclear bomb from scratch, focusing on the scientific principles and immense challenges involved, particularly the sourcing and enrichment of uranium. To create an atomic bomb, uranium is essential. Specifically, uranium-235 is required, which is incredibly rare. It can be found within pitchblende, a radioactive material once mined in France. Pitchblende contains about 50-80% uranium, but only about 0.7% of this is uranium-235, the isotope needed for the type of bomb discussed (fission, not plutonium-based). To replicate the Hiroshima bomb, which used 64 kilograms of uranium-235, one would need to mine approximately 14 tons of pitchblende, assuming no loss during enrichment.
