Koeberg desalination drive
Nuclear plant responds to Cape water crisis
Eskom’s Koeberg nuclear power station launched its groundwater desalination plant yesterday.
It will take care of the power station’s water needs and ease pressure on the City of Cape Town’s water supply.
Power station manager Velaphi Ntuli said the plant was part of Koeberg’s threepronged water management strategy to address water shortages in Western Cape while ensuring it was able to provide safe and sustainable electricity.
The strategy entails “reducing the power station’s daily water use‚ keeping adequate on-site water storage‚ and looking at alternative water supplies [groundwater and sea water]”.
“When the City of Cape Town called on the people of the Western Cape to address the water issue‚ we had to respond with a sustainable solution as a responsible corporate citizen.
“To this end we have saved approximately 115 000 kilolitres since June 2017‚ compared to previous averages. This equates to the City of Cape Town supplying 10.5 kilolitres of water to approximately 11 000 houses for a month,” said Ntuli.
“Our water tanks are kept full to cater for emergencies.”
Koeberg‚ Africa’s only nuclear power station‚ provides 50% of Western Cape’s energy needs and about 5.6% of South Africa’s. It can only operate for about two weeks without offsite potable water.
Ntuli said the power station saves 22 billion litres of fresh water per year as its condensers are cooled by sea water‚ which is returned to the sea after use. –
