In 1989, South Africa became the first, and only country to make and then dismantle nuclear weapons.

The project was conducted at Kentron Circle, a secret weapons facility.

André Buys was plant manager and systems engineer at Kentron Circle and was involved in making the weapons.

He tells Gill Kearsley about his work on this once top-secret project.
