No radiation leak after ‘contamination’ events at Africa’s only nuclear plant, regulator says

South Africa’s nuclear regulator confirmed no radiation leaked into the environment during three 'contamination' events at the Koeberg Power Station. The incidents, caused by power loss to ventilation units during maintenance, were contained, with worker exposure levels below those from a dental X-ray. Koeberg, Africa’s only commercial nuclear plant, provides 5% of South Africa’s electricity and recently received reactor life extensions.
