Are storage centres safe?
Surface storage centres, reserved for waste with a relatively short lifetime, are built in regions where seismic risks are very low. Furthermore, the construction of cells for storage, filling them and ulterior treatment with land cover plus surveillance for at least 300 years makes them safe for this period of time. The underground storage centres being studied at present, intended for waste with long lifetimes, are chosen only in terrain that has been stable for millions of years. According to even the most pessimistic scenarios, the risks of contamination for human beings still remain negligible.
