I predict that the number of PBR's that are ultimately built will be less than 100, including the 25 South Africa intends to build. There will be many thousands of high temperature reactors built if humanity survives global climate change, but the PBR is at best a short termer. It's a Gen III type, but most of the high temperature reactors to be built will be the Gen IV types. It's too difficult to recycle the fuel.
But from what I understand, Eskom has become very politicized since the end of apartheid.
