The 40-year operating licence of unit 1 of the plant outside Cape Town was due to expire this month, but state-owned utility Eskom applied for a 20-year extension to operations as part of efforts to end crippling power shortages.
Some environmental activists opposed the application, citing heightened safety concerns.
The NNR board of directors approved the granting of the application for Koeberg nuclear power station unit 1 to operate for 20 years until 21 July 2044 subject to - safety improvements identified as part of the third periodic safety review, NNR CEO Ditebogo Kgomo said.
The regulator is still assessing Eskoms application to extend the life of Koeberg unit 2 by another 20 years, but that units licence is valid until November 2025.
Koeberg, currently the only operational nuclear power station in Africa, has a capacity of around 1.9GW, accounting for roughly 5% of the electricity generated by Eskom. Wendell Roelf, with Tannur Anders, (c) 2024 Reuters
