The fear of nuclear war forced nations to come together to stop the spread of atomic weapons. Could a similar idea curb the use of fossil fuels?

Nuclear waste remains toxic for thousands of years. How do you build a storage facility that will keep it safely buried for millennia?

Astronauts living on the Moon will need lots of power – but they can't take fuel supplies with them. A new generation of miniature nuclear reactors could be the answer.

In the years after World War Two, neutral Sweden embarked on an ambitious plan – build its own atomic bomb.

The atomic bomb tests at Bikini Atoll in 1946 were too dangerous for conventional aircraft to observe. Pioneering remote-controlled drones, however, were a perfect match.

Since the 1990s, a network of sensors has listened for unauthorised nuclear detonations. It has had unanticipated upsides for science – such as identifying a pod of pygmy blue whales.

In the early years of nuclear research, some scientists feared breaking open atoms might start a chain reaction that would destroy Earth.

In a few years, Finland will begin depositing spent nuclear fuel underground in Onkalo, where it will remain for millennia. Erika Benke describes her experience of visiting the site.
