Construction of Koeberg began in 1976 and Unit 1 was synchronised to the grid on 4 April 1984, with Unit 2 following suit on 25 July 1985.
Koeberg, the only nuclear power station in Africa, has a pressurised water reactor (PWR) design. It boasts
the largest turbine generators in the Southern Hemisphere and is the most southerly-situated nuclear power station in the world.
Koeberg is surrounded by a 3000 ha private game reserve owned by Eskom, containing more than 150 species of birds and half a dozen small mammal species.
Low and intermediate level waste from Koeberg is transported by road in steel and concrete containers to a remote disposal site at Vaalputs, 600km away in the Kalahari Desert. High level waste, the spent fuel, is stored on site in special pools quipped with high-density racking.
Koeberg ranks amongst the safest of the world's top ranking PWR's of its vintage and is the most reliable Eskom power station. In March 2001, Koeberg was awarded NOSCAR status for the 5th time by the National Occupational Safety Association (NOSA).
The station is also vital for grid stability in the Cape.
