The first forms of PBMRs were developed by a South African team working in Eskom’s PBMR company.
Eskom planned to construct a PBMR at Duynefontein near Koeberg, but after a decade of development and ballooning costs with a lack of investment, the project was shut down.
Two former members of this team — Eben Mulder and Martin van Staden — have been scooped up by X-Energy. They serve as the company’s chief scientist and lead reactor developer, respectively.
