South Africa is lifting its Pebble Bed Modular Reactor (PBMR) out of care and maintenance, Electricity and Energy Minister Dr Kgosienstsho Ramokgopa has confirmed, almost in passing.

He was delivering the keynote address at the Enlit Africa 2025 conference, at the Cape Town International Convention Centre.

The PBMR is a small modular nuclear reactor (SMR). It was being developed by South Africa from 1994 (although the preliminary work predated that year) to 2009, when it was effectively terminated, through being reduced to a care-and-maintenance status. The scientists and engineers who had worked on the project scattered to the winds, with anecdotal reports indicating that at least some of them emigrated, to work on other countries’ nuclear projects, although others did remain in South Africa.

In November, Ramokgopa had revealed that he was going to recommend to Cabinet that the PBMR project be revived. When the project was reduced to care and maintenance, South Africa was probably the world leader in SMR development. That position was lost, years ago.

“Of course, we are lagging behind,” he acknowledged. But he assured that the country could catch up, by cooperating with one or other of the major nuclear energy powers.

He pointed out that SMRs would be more rapidly deployable than traditional, large, nuclear power plants (NPPs). This was because they would be at least partly modular in construction (and assembled on site from components manufactured in factories).

He reaffirmed South Africa’s overall commitment to nuclear energy. He pointed to the country’s NPP at Koeberg, near Cape Town, which was Africa’s only operational NPP. (He did note that Egypt was busy constructing the continent’s second NPP.)

Ramokgopa also highlighted that countries that had significantly decarbonised their energy systems had done so using one or other (or both) of just two forms of electricity generation. These were nuclear and hydro.

Nuclear could provide clean baseload power. Nearly all the world’s major economies now recognised nuclear power as clean power, he pointed out.
