Cabinet has given the go-ahead to revive the pebble bed modular reactor programme, which will allow for the further development of the nuclear technology which was mothballed in 2010.
The decision allows the South African Nuclear Energy Corporation (NECSA) to engage international partners and investors for the further development of the project.
The move aligns with government’s latest Integrated Resource Plan that relies heavily on nuclear and renewable sources to generate the majority of South Africa’s electricity by 2039.
In the 1990s, a South African company was established to develop and market small-scale pebble bed modular reactors based on the German technology.
But the project was shuttered in 2010 after delays and cost overruns and many of the scientists went abroad.
Minister in the Presidency Khumbudzo Ntshavheni said the revival was in line with the country’s future energy vision.
"This decision will enhance South Africa’s ambition to participate in the nuclear fuel cycle and position the country to play a critical role in the development of small modular reactor technology."
Cabinet has also welcomed an announcement by the national nuclear regulator to extend the life of Koeberg Unit 2 by another 20 years to 2045.
"This is a significant milestone that strengthens South Africa’s long-term energy security and reflects Eskom's commitment to world-class nuclear safety standards."
Cabinet has also expressed satisfaction about the registration of 181 new generation facilities with an investment value of over R30 billion during the second quarter of this financial year.
