A nuclear power plant in South Africa encountered three incidents involving “airborne radioactive contamination” following a power outage. These contamination events occurred on June 30, July 2, and July 7 within the Koeberg Power Station, which is the sole nuclear power facility in Africa.
The South African nuclear regulator confirmed that during the incidents, no radioactive substances escaped into the environment, and all contamination remained contained within the station, posing no risk to the public. The National Nuclear Regulator reported heightened airborne radioactive contamination at the facility on the west coast of South Africa due to a loss of power to ventilation systems during maintenance activities.
Employees working inside the power station who may have been exposed to the contamination underwent screening, revealing levels below those typically experienced during a dental X-ray. The regulator emphasized that the recent events, although under further scrutiny, did not meet the criteria for classification as a nuclear or radiological emergency and did not result in any radiological effects outside the site.
Situated approximately 25 miles north of Cape Town, South Africa’s second-largest city, the Koeberg plant stands as the continent’s only operational commercial nuclear power station. Commissioned in the 1980s during the apartheid era, the plant comprises two reactors contributing about 5% of the country’s electricity and is overseen by the national utility provider, Eskom. Recently, the plant’s reactors received 20-year life extensions, allowing them to remain operational beyond 2040.
South Africa aims to bolster its nuclear energy capacity by constructing new power stations to address its unreliable and environmentally damaging energy supply. This initiative is driven by the need to accommodate a growing population heavily reliant on coal for energy. Despite safety concerns from nuclear power opponents following incidents such as Chernobyl and Fukushima, many countries, including several African nations like Egypt, are increasingly turning to nuclear power to meet escalating energy demands.
Egypt, for instance, is constructing its inaugural nuclear power station equipped with four sizable Russian reactors, slated for operation around 2030 to supply approximately 10% of the country’s electricity, as reported by the World Nuclear Association.
