A nuclear waste dump for eternity
France has found a €25 billion solution to the unanswerable question of what to do with its high-level nuclear waste - bury it deep underground.
While nuclear energy has a small carbon footprint, its waste still produces a puzzling problem for the industry. For the moment, it is treated and held in temporary sites but the plan is to store it 500 metres below the Earth's surface.
Our team from Down to Earth went to the most radioactive waste site in Europe where the spent fuel is waiting to be buried, before visiting the underground tunnels that may be the final resting place for this indestructible toxic trash.
