Seventy years ago, electricity was generated by a nuclear reactor for the very first time at the EBR-I experimental station on the outskirts of Idaho, USA.
Three years later, in Obninsk Russia, a nuclear power station would go on to produce the world's first ever electricity for a power grid.
Through the 1960s and 70s many more nuclear reactors were constructed all over the world, with many countries envisioning a future of cheap and emission-free electricity.
