While some see Eskom’s synchronization of Unit 2 of the Koeberg Nuclear Power Station in Cape Town to the national grid yesterday, as a step to end loadshedding.
Organizations such as the Koeberg Alert Alliance and the Southern African Faith Communities Environment Institute (SAFCEI), have previously expressed concerns about the environmental impact of nuclear reactors at Koeberg.
The National Nuclear Regulator (NNR) asked for comment on health, safety and environmental issues connected with Eskom’s licence change application for the construction of a spent fuel cask storage area at Koeberg. The public have 60 days to comment.
On Tuesday morning, Eskom said this step is a milestone in the Generation Operational Recovery Plan and South Africa’s pursuit of a dependable, cost-effective, and environmentally sustainable energy supply.
Eskom said the maintenance programme for Unit 2 included the replacement of three steam generators, comprehensive inspections, and refuelling activities to ensure the reactor’s continued safe and efficient performance. These enhancements align with Eskom’s broader strategy to secure the future of Koeberg’s reactors, which are critical to the country’s energy security.
Unit 2 is expected to contribute about 930MW to the grid.
The National Nuclear Regulator (NNR) is anticipated to decide on the extension of Unit 2’s operational license in 2025.
This comes after the successful renewal of Unit 1’s license, which extends its operation until 2044.
Eskom also said Unit 1, contributing 930MW to the grid, has shown exceptional
reliability since its return to service.
Combined, Units 1 and 2 will supply 1 860MW—approximately 5% of South Africa’s total electricity—playing a vital role in reducing loadshedding and stabilising the grid.
Bheki Nxumalo, Group Executive for Generation, said “by forming strategic collaborations with international designers, suppliers, and industry leaders, Koeberg has established itself as a hub for nuclear innovation. These partnerships are anticipated to be crucial as South Africa explores advanced nuclear technologies, such as Small Modular Reactors (SMRs). This could position the country as a leader in cutting-edge nuclear solutions while continuing to build and maintain a skilled nuclear workforce.”
