Stratek Global has secured a 2,000-hectare site at Zilkaats Estate on the border of Gauteng and North West provinces for deployment of its HTMR-100 reactor. The project represents a R5.7 billion investment. The HTMR-100 is a high-temperature helium-cooled SMR derived from South Africa's earlier Pebble Bed Modular Reactor programme. A separate ZAR 9 billion (approximately USD 480 million) financing arrangement between Koya Capital and Stratek Global has also been reported for the project. The "100" in HTMR-100 refers to the reactor's approximately 100 MWt thermal output; net electrical output is approximately 35 MWe.
