El reactor nuclear de hace dos mil millones de años | Alfredo García Fernández | TEDxReus
Hace 2000 millones de años, en Gabón existió un reactor nuclear natural que generó varias toneladas de residuos radiactivos sin afectar a su entorno. La naturaleza nos muestra como es posible gestionar esos residuos, a pesar del miedo y rechazo generalizados. Con este ejemplo, Alfredo nos muestra como la energía nuclear puede contribuir a la mitigación del cambio climático de forma segura.
